Hydraulic steering wheel (GUR) - component part of the car, the purpose of which is to optimize the handling vehicle and its operation. Determines, and most importantly, the safety of driving process depends on the performance of the hydraulic device.
Violation normal work The power steering can be triggered by the following faults:
- tightness disorders of the steering system,
- hose damage
- natural wear of parts.
All listed facts lead to a qualified repair.
Troubleshooting GUR
Possible reasons why the steering hydraulic power plant does not work, and how to fix them, consider below.
Return jackets on the steering wheel (return)
Possible cause - weak tension drive belt Pump, or this belt is worn out. Elimination of such a malfunction will not take a significant amount of time and means, because it is necessary to replace the belt or adjust its tension.
Steering wheel scrolls with effort
If the steering wheel with a hydraulicer is tight, then there may be several reasons for such a malfunction:
- weak tension of the pump drive belt (adjust the tension),
- low (critical) fluid level in the tank GUR (add liquid),
- tank Bush Filter Gur (Replace Filter),
- low operating pressure of the pump on the hydraulicel (replace or repair the pump),
- air in GUR (remove the accumulated air and check the tightness).
Liquid in GUR must be addressed by the one that was filled initially. To do this, it is better to store the container in which the liquid was sold.
Wheel rotation requires effort
The reason for such a malfunction of the power steering is one - a malfunction of the pump. Elimination is to check and repair the pump, replace its seals.
Steering wheel in the middle position spinning with great effort
- pump malfunction, which can be replaced by the part, or its repair,
- mechanical malfunction - it is recommended to diagnose the steering system.
Vibration
Possible causes of malfunction:
- mechanical damage, dangerous tire state (reveal defective tires, repair them or replace them with new),
- air hit in hydraulic system (Remove air, after setting the reason for its hit).
Noise at work
Causes of fault:
- low level Gur liquids in a tank (eliminate leak, check the tightness and add liquid),
- damage (wear) high and high hoses low pressure (in this case, the hoses check and replace the failed),
- the accumulation of fluid through safety valveis accompanied by a whistling sound with the extreme position of the steering wheel (check the operation of the pump, in the case of its failure to replace).
Fuzzy steering
- violation of the steering geometry (it is necessary to check the status of the tire),
- worn steering parts (check the visual status of parts and nodes, eliminate their malfunctions),
- leak fluids (check with tightness).
As can be seen from the listed faults, most often the power steering is badly working due to fluid leakage, which serves as lubricant. At the same time, the car begins to "buzz" strongly, and when the steering wheel turns, this hum is enhanced, so when a liquid decreases, it is necessary to urgently look for a leakage place, otherwise the pump will fail, and this item is very expensive.
Power steering, as mentioned above, affects running part car so it good job - Pledge of a good trip. In the case of suspicion of incorrect operation of the GUR, it is recommended to stop moving and continue after repairing the hydraulic agent.
Complicated designed systemwhich requires periodic attention from the owner. The liquid that is poured into the tank and is the basis of the system functioning, has a certain service life, after which it loses its properties and turns into an incomprehensible mixture. In this article, you will learn what problems may arise after the replacement of the GUR liquid, why the steering wheel becomes a tight or too easy, as well as the causes of such manifestations.
The steering wheel began to spin the tight
Increased steering wheel force may be observed for a number of reasons. Some of the main:
- Worn or not enough tight stretched strap, because of which there is no sufficient pressure for the pump operation.
- Lack of fluid in the GUR tank.
- The scored filter of the liquid or the presence of the system enforcement.
- Lack of revolutions at idle.
- The failure of the elements of the steering system.
Most often, the problems with the hydraulicifer are manifested with a car. So the oil enters the system, heats up and performs its functions. Any diagnosis of the hydraulic device is important to carry out in suspended form to reduce the load on the steering elements.
Important! When conducting a replacement you need to use only original liquid. Counterfeit oil can lead to disorders in the operation of the hydraulic agent and entail expensive repairs.
Also, the steering wheel may require additional efforts only when turning turns, and during the rest of the movement fully fulfill its functions. In this case it is necessary to diagnose the steering rack.
In GUR hit the air
In this case, the steering wheel simply does not listen, it is impossible to drive a car. If you need to turn sharply, you have to make big efforts.. Also, vibration occurs when turning into one of the parties. It is necessary to find a place where the system was depicted, and eliminate the problem, then remove the air or pump the system.
Something scored valve
When the valve is scored, the hydraulicel will work with a little effort, it means that the driver can rotate the wheel only if it makes more effort. It is difficult, and for turns to the left or right will need to be applied. Periodically, various particles of dirt fall into the oil or a precipitate from the use of additives is formed.
Did you know? In 2013, a record was recorded on the run of the car, which is in working condition. It was put on the Volvo 1900 S, the mileage of which at that time was 4,828,032 km (this is equivalent to 120 round-the-world travels).
All this can scratch the walls of the pump or bring the stripping and tube of the system, which reduces performance.
Not the original oil
It is impossible to turn the steering wheel without additional effort. Inappropriate fluid is able to cause great harm to all elements of the system, such as gaskets, tubes, as well as all surfaces of the pump. It is necessary to choose and fill the liquid correctly.
It is recommended to replace the liquid GUR in a specialized car service. Masters know typical problems Hydrauscitel, have the necessary equipment, tool and knowledge to correct problems or conduct planned procedures
Liquid leakage
The steering wheel turns hard or too easy. Unbalanced operation of the entire steering mechanism is noticeable. In case of insufficient fluid, the GUR will cease to work at all. You need to check the hoses, eliminate the flow, restore tightness and pump the system.
Worn gur
Unbalanced operation of the steering mechanism. At the same time, the steering wheel rotates with great effort. Additionally, a very strong hum is heard, which is enhanced by turns.
You need to carry out a thorough revision of all nodes and, if necessary, repair or replace them.
The steering wheel became easier
After replacing the oil in the hydraulicel, the driver may notice that the steering wheel has become slightly easy to control. If during technical work No errors were allowed, this is caused by changing the type of fluid in the system.
For each car, the manufacturer indicates recommended oil with its chemical composition depending on the characteristics of the steering elements. Oil transfers force when exposed to pressure and lubricates fuel. Accordingly, with insufficient density and viscosity of the oil, the desired pressure in the system will not be created, and the steering wheel will spin easily.
Video: Why change oil in gur, signs, consequences, test liquids
However, there are a number of other reasons for which the steering wheel may become easier to manage. If the replacement of the fluid was made to the compliance with all the rules, it is necessary to diagnose the elements to find the cause of such a steering behavior.
Unusual management
Competitive auto steering system - base base while driving. Excessive ease of steering, even if it is not caused by technical failures in the system, can lead to. The initial reason for this is the problem of manageability, since the car is increasing sharpness during maneuvers and significant sensitivity appears when driving even in the direction directly. In other words, the car comes out from under the control of the driver. A minor bump, a pit or a quickly emerged obstacle to the machine with an unnaturally lightweight can be caused by emergency situations. In addition, the wear of the hydraulicel increases, which will lead to an ambulance of its replacement and the accompanying elements.
Did you know?In 2010, Volkswagon Scirocco managed to drive a distance of 337 km from London to Manchester exclusively for coffee. The modified car processed coffee granules, turning them into carbon dioxide and hydrogen, while the machine could develop speed up to 100 km / h at the flow rate of "fuel" - 56 cups of espresso.
Mind of viscosity of oil
Liquid viscosity for GUR - one of the main indicators. There are several types of oils on the market, which have a different chemical composition and for convenience painted in different colors. Automakers in technical documentation indicate the preferred oil for each auto model. It is recommended when replacing a fill with the same fluid, since the working pressure created in the GUR directly depends on its consistency.
Each car owner has a desire to change the liquid of one species to another or in order to improve work, or to save money. When not this falls into the system dense oilAs it was before, it could cause the hum of the hydraulic pot pump.
Hydraulic steering wheel performs an important role in managing the car. Over time, some problems may arise, however, subject to the duration of the liquid replacement in the GUR, you will extend the time of the hydraulic power service.
Good day! Faced a problem that I can't solve the second week. After replacing the liquid, the GUR steering wheel began to rotate tightly.
Below I describe the entire proceeding process.
From the moment of purchase, the pump gur was crying, and the liquid was at the MIN mark. Here are the hands to replace the gland and, accordingly, the replacement of Things.
Eneos fluid ATF Dexron. III - 522 Empty Corteco 19029685B (sizes 19.05 x 33.3 x 7.9 mm) - 174 rubles
Did, like everything here, who changed the gland. Having posted the front wheels. Purpped the liquid from the tank. Unsigned and removed the clamp. Removed the nozzles. I merged with them all the liquid, twisting the steering wheel there and here. Unscrew the nozzles from the pump. I merged with them all that was there. Ssed the pump. All the parts are framed. Identified the old gland. The inside of the pump. Scored the end head a new gland.
Full size
New Corteco Seal 19029685B
Collected all parts of the pump in the reverse order. Screwed the pump in his place and pulled the belt. Screwed the nozzles to the pump. The tank pulled down and put it in place. I tried the hoses to the tank. Khomutov replaced new ones. I did not rush new liquid In the tank to the MAX mark. 
Full size
ENEOS ATF DEXRON III Liquid
After that, I started pumping. First twisted the steering wheel. Then he threw the food from the ignition coil and twisted the starter for 10 seconds and simultaneously twisted the steering wheel. Liquid leaving. Topped fresh.
As the liquid ceased to leave, attached power to the coil. Continued pumping on the already headed engine. After several attempts, the liquid almost did not leave. But air bubbles still remained. Twisted the steering wheel again 50 in the same way. The air was still out. Zhai foamed. The day ended and it was necessary to go home. I spat on this business and lowered the car. The steering wheel became shout without hydraulic. The next day I went to give the system, but as I did not twist the steering wheel, I did not really change anything. Twisted 100 times in all sorts of modes and with the engineered and not installed engine. Air bubbles still went out but not so much.
Now I sit think about what options may be. Is the reason in the air? How long in this case, it is still pumped? It seems how many times I have already twisted the wheel, it was long ago came out. Already the thought of removing the pump to see, maybe there is something wrong. Although it seems to assemble everything as it was. I do not know what to think.

Tightly spinning steering wheel with a hydraulic agent: possible causes. Repair GUR.
Without a hydraulic power steering (GUR), no car is required today, the equipment of which was performed with the orientation on the modern level of driving comfort. Hydraulic mechanism facilitates the physical control of the machine, while maintaining the optimal degree feedback and compliance with safety requirements.
This is achieved by the introduction of auxiliary mechanism into the steering wheel system, the technical condition of which should be regularly monitored. If, after a certain time of using the machine with such equipment, deviations in the operation of the mechanism are noticed, then it should be prepared for its repair. For example, if the steering wheel with a hydraulicer is tight, there may be several options for the output. But you must first consider the design of the mechanism and the principle of its work.
The hydraulicer system is multicomponent, but closed. Partly such a device and caused the complexity of the construction of the structure. The standard mechanism includes a pump, a tank with a tank liquid, a pressure regulator, a power unit and a spool. The pump connects to the drive engine of the machine, and the pressure regulator ensures the balance of the force consumption relative to the spool. The operating drop in pressure indicators depends on the reserve of the control fluid.
It is this part of the functional in most cases and leads to malfunctions, due to which it is required to repair the GUR in the form of correction of the position of individual parts of the design or by means of oil updating. In turn, the hydraulic cylinder interacts with the steering rack, translating additional effort. In order for the final load required to enable the steering into activity, the spool itself is installed on the column - in the future it will react to the rotational moment when manipulating the driver.
The feeling of gravity when controlling the steering wheel does not always appear sharply and at one point. This may be a long process, during which warning signs may arise. In particular, the primary diagnosis will help to detect the problem on the formation of leaks, noise and excessive vibrations. Over time, the tight steering wheel is added to this list, if the same flow is not stopped, and the supply of fluid is replenished. Of course, the above features may indicate the emergence of other problems, and not only with the hydraulic agent. Therefore, the general diagnosis in this case It will not be superfluous. It will make it possible to more accurately determine the possible cause of weighting of the steering wheel.
The main causes of the steering work
Factors that can lead to the difficulty of the steering wheel due to the hydraulic agent, a lot. Each of them involves its approach to repair. One of the most common causes is the presence of air in the hydraulic amplifier niches. Its presence does not simply level main function The mechanism, but also gives the opposite effect, taking the movement of the steering wheel.
One more frequent cause - This is said devastation of the expansion tank with liquid. If it was not possible to determine the reason why the steering wheel is spinning with a hydraulic powerover, that is, it makes sense to contact technical state Separate components of the system. For example, wear of parts, especially the drive belt, indirectly could provoke a decrease in the hydraulics function. In this case, it is not possible to avoid the complete revision of the mechanism and, possibly, its replacement. Do not exclude the probability of a problem in the steering itself. For example, the rail in parts of a bundle with a gearbox can deliver even more troubles in terms of repair.
How to disassemble a tight steering wheel?
To make sure the reasons for which the steering wheel action could occur, the mechanism should be disassembled. The event begins with disconnecting pipelines that lead to expansion Bach and the steering system. At this stage, you can drain the liquid. Next, the drive belt is removed from the pump - again, if it is in an unsuitable condition, then new tape will have to wear.
Here, three block fixation blocks are unscrewed, suitable for a pump unit. But depending on the type of fasteners system, it can be more. After that, access to the elements of fixing the pump itself can be discussed. As can be seen, the repair of the GUR can be performed already at this stage, replacing the fluid by updating the hoses and the drive belt. But this may not be enough. Separate attention should be done with the filtering system. Even if it regularly performs its function, the violation at the cleaning phase is not excluded, which cannot be determined in garage conditions. Therefore, if there are no other obvious causes a problem, it makes sense to check filters in a professional workshop.
Out of excess air
If the reason is to have excess air in the system, then in a sense you can talk about luck. True, everything is ambiguous here. Most often, this problem is solved by several rollers, communicated to the stop. And this action is performed in both directions. As practice shows, it allows you to push the excess air from the hydraulics communications. But if after this action is seriously spinning the steering wheel, then with a greater probability there was a trusting of the tank. This means that the system works with a liquid in which bubbles are present. This factor determines the absence of ease in handling the steering wheel. Eliminate this problem will help the full renewal of the fluid in the expansion tank.
Replacing fluid
This is not necessary to make a complete analysis of the mechanism. First of all, two nozzles leading to the expansion Baku should be released from the clamps. Also, additional fasteners and belt communications are removed if necessary, due to which access to the tank is difficult.
Immediately the replacement of the liquid can be performed and without completely dismantling the tank. The spent mixture is simply pumped up, after which it remains to pour out new auto chemicals. However, if the steering wheel is tightly spinning, which has not been checked for a long time, it is desirable to dismantle the tank for subsequent diagnostics. It should be checked for tightness, then rinse thoroughly and rinse clean water. The dried tank is installed in its place, filled with a new working fluid and fixed fasteners.
The question of the choice of fluid for the hydraulic agent also imposes considerable responsibility. Preferred preferred synthetic hydraulic mixtures made of high-quality components. Normal machine oil In this case, it is not suitable. The peculiarities of specialized compositions include sufficient degree of fluidity, viscosity and ability of work at extreme temperatures.
Often the problems of this kind are found in winter timeWhen the flooded fluid is elementary not coping with its tasks due to the freezing. Therefore, the question of which oil in the power steering wheel should be poured, should be solved only in favor of special synthetic or semi-synthetic mixtures, which usually have a dark green shade. If we talk about manufacturers, then high-quality auto chemicals of this type are produced by Motul, Castrol, Pentosin, Liqui Moly. etc. The cost of liquid is about 800-1000 rubles, but even a small canister is enough for a long time, therefore it is not worth saving on this resource.
How to replace heavy steering wheel?
The dismantling of the system begins with the mentioned disconnection of all pipelines, nozzles and fasteners. Also, oil is mandatory or pumped out, covered in an expansion tank. Installing a new system is made in reverse order. If we are talking about the full update of the steering complex, then in this case you will have to dismantle the rack itself. Such a replacement of the power steering should be carried out in conditions where there is a mounting straight stand. The installation begins with the integration of the steering wheel, and then alternately integrated the components of the hydraulics. Last fill working fluidand compete elements of communication support.
Conclusion
By itself, the system of facilitating control of the steering wheel is quite complicated and often causes the problems with identifying the reasons for its incorrect work. If there is a tight steering wheel with a car's hydraulic cylinder, whose wheels are lazed, it is quite possible that the problem will be in insufficiently pumped tires.
In this situation, the difficulty is already associated with the mechanics of the interaction of rubber coated, the effect of which is transmitted even on a good hydraulic. Also, insufficient tension of the drive belt may affect the function of the amplifier. That is, before proceeding to repair workThe user must make a complete inspection of the car for the availability of factors that can affect the operation of the steering rack.

Tight steering wheel gur - Logbook DAEWOO ESPERO \u003d REAL-REMI \u003d 1998 on DRIVE2
Guys tell me what could be the case. In total, a month ago, the liquid began to leave, at the exit of the barrel where the thick nozzle was lower. I thought about Hamute, I changed still flowing ... I decided to buy a new hose, again flowing ... I took off the tank began to look at and saw the Maaalen crack in that place. Slised superclaim)) I was enough for 3 weeks and flowed again. Yesterday I bought a tank and liquid Mannol Dexron III, but the problem is that I no longer remember what of the two poured ... either Dexron III or DEXRON II ... KnockakA was told to me in principle III is more higher than the class and nothing terrible if it was flooded by II ... and Maybe I'm III and poured)) In short to all procedures, the steering wheel spinning easier to 30-40 than after. Yesterday replaced the tank, the liquid by and large most of the part merged and poured a new one ... After the started, I was crushed (the steering wheel, here before the stop did it before), filled to the level of Max ... There are no bubbles in the tank, GUR is not buzzing everything is OK. Right now, I drove in the morning and immediately noticed that I became the tight ... that you still stand in place (head), that in the movement the same. In the same way, the turn was soothe to turn two hands. What can be wrong? The fluid level right now above the MAX mark per 1 cm. This can somehow influence?))) Who pours to yourself?
PS Once again I remind you that before replacing the tank, the steering wheel was light, i.e. The pump is whole and all that ...
What to do, if buzzing gur? This issue periodically wonders most of the car owners, this system is installed in whose machines. What could be the causes and effects breakdown? And is it worth paying attention to this?
Reasons why buzzing gurmaybe several. Outsided sounds indicate an explicit malfunction in the control system. And the sooner you eliminate it, the more money will save and you will not be at risk to get into the emergency with the faulty steering system of your car.
Device hydraulic
Causes of Gula
An unpleasant hum of the steering hydraulic power can occur under different circumstances. Let us dwell on the most basic reasons why Hur is buzzing when turning:
- Low fluid In the hydraulic system. You can check this visually by opening the hood and looking at the oil level in the expansion tank of the GUR. It must be between MIN and MAX marks. If the level is below the minimum mark, it is worth adding a liquid. However, before that, it is necessary to find the cause of leakage. Especially if after the last topping passed a little time. As a rule, leak occurs on the clamps and in the fields of joints. Especially if the hoses are old. Before plot, be sure to eliminate the cause of the leaks.
- The inconsistency of the flooded fluid of the one recommends that the manufacturer recommends. This may cause not only the roast, but also more serious faults. Also bear gur in winter Maybe due to the fact that the liquid although the specification corresponds to the specification, however, it is not intended for operation in special temperature modes (with significant frosts).
Dirty liquid GUR.
- Low Quality or Pollution liquids in the system. If you purchased the "pale" oil, then the likelihood is that after some time it will lose its properties and GUR will start to buzz. As a rule, together with the roar you will feel that the steering wheel has become harder. In this case, be sure to check the quality of the oil. As in the past case, open the hood and look at the condition of the liquid. If it has been soothed significantly, and even more so, composed, it is necessary to replace it. Ideally, the color and consistency of the oil should not be very different from the new. Check the condition of the fluid can be "on the eye." To do this, you need to score a syringe some liquid from the tank and drop it onto a blank sheet of paper. It is allowed red, crimson burgundy, green or blue colour (depending on the original used). The fluid should not be dark - brown, gray, black. Also check the smell emanating from the tank. From there should not pull with a burning rubber or burnt oil. Remember that the replacement of the fluid must be carried out in accordance with the schedule approved in the manual of your car (as a rule, it is changed every 70-100 thousand kilometers of run or once every two years). If necessary, make a replacement of oil. List best liquids For the hydraulic system, you will find in the appropriate.
- Finding air to the system. This is a very dangerous phenomenon that is harmful to the gur pump. Check the presence of foam in the expansion tank of the hydraulic system. If it takes place, then it is necessary or to replace the fluid.
- Faults of the steering rack. It can also cause a roast. It is worth conducting it visual inspection and diagnostics. The main signs of the rack malfunction are the knock in its housing or from one of the front wheels. The reason for this can be the failure of the gaskets and / or damage to the anthers of the steering, because of which the leakage of the working fluid is possible, the dropping of dust and dirt on the rail, the occurrence of the knock. In any case, it is necessary to carry it out with the help of repair kits sold in auto shops. Either ask for help per service station.
Do not drive with a faulty steering rack, it can lead to its jamming and accident.
- Weakening drive belt GUR. Diagnose it is simple enough. The procedure must be performed after the engine has worked for some time (the longer - the easier it is to diagnose). The fact is that if the belt slips on the pulley, it becomes hot. In this you can make sure that I touched it with your hand. For tension, you need to know efforts, with which the belt should be stretched. If you do not have a manual and you do not know efforts - go for help in the service. With excessive wear of the belt, it is necessary to replace it.
- Malfunction pump GUR.. This is the most unpleasant and expensive breakdown. Its main feature is an increase in efforts to turn the steering wheel. The causes of the fact that the pump gur buzzes is buzzing, there may be different parts of the pump - bearings, impeller, glazes. You can familiarize yourself with the methods of diagnosing and repairing GUR.
Buzzing gur on cold
Detection of GUR and Steering Rake Faults
There are several reasons why GUR is buzzing on cold. The first is that it goes air Sleeping through Low Pressure Highway. To eliminate it, it is enough to put two clamps on the tube coming from the tank to the pump GUR. In addition, it is worth replacing the ring standing on the suction nozzle of the pump itself. After installing the clamp, we recommend that you use the oil-resistant sealant, which you need to miss the clamps and connectivity.
It is also possible to conditionally distinguish another reason, the probability of which is small. Sometimes there are cases when insufficient (poor-quality) pumping system GUR. In this case, the air bubble remains at the bottom of the tank, which is removed using a syringe. Naturally. that its presence can cause a marked hum.
Development methods can be replaced by oil hoses and / or rails, replacing the pump GUR, setting additional clamps to all hoses in order to eliminate air seats into the system. You can also perform the following procedures:
- replacement of the sealing ring on the spout of the expansion tank;
- installing a new hose from the tank to the pump using oil-resistant sealant;
- perform the airborne procedure from the system (when performing a procedure on the surface of the liquid, bubbles will appear, which you need to give time so that they fall) the rotations of the steering wheel on the non-running motor;
Another option is to replace the sealing ring in the suction hose hose of the Gur (and if necessary and the hose itself and both clamps). The fact is that over time it loses elasticity and becomes tough, that is, loses elasticity and tightness, and begins to pass the air, which enters the system, causing knocks and foam in the tank. The output is to replace this ring. Sometimes the problem may arise due to the fact that it is not easy to choose a similar ring in the store. But if you found it, be sure to replace and put on the mount and lubricate the oil-resistant sealant.
For some machines, there is a special remak set of the hydraulic agent. In the event of problems with this node, the first thing you need to buy Remkomplekt and change rubber stripswhich are included in its composition. Moreover, it is advisable to buy original sets (especially relevant for nonsense foreign cars).
Pump Bearing Gur.
Also need to follow lack of dirt in fluid system. If it is present even in small quantities, over time, this will lead to the wear of the waterproof pump parts, because of which it will begin to make unpleasant sounds and it will work worse, which will be expressed in increasing the effort when turning the steering wheel, as well as possible knocking. Therefore, when replacing the fluid, you will definitely look at the bottom of the expansion tank of mud sediments. If they take place, you need to get rid of them. Check the filter in the tank (if it takes place). It should be relatively clean and integer, firmly fit to the walls of the tank. In some cases, it is better to replace the fully tank with a filter than to try to clean them. Also in this case, it is necessary to remove the rail, disassemble it, rinse from dirt, as well as replace rubber-plastic parts. To do this, use the mentioned Remkomplekt.
Unpleasant sound can produce outer bearing pump GUR. Its replacement is easily carried out, without the need for complete disassembly of the node. However, sometimes it is difficult to find him a replacement.
There are special additives that are added to the hydraulic fluid liquid. They eliminate the buzz of the pump, remove efforts on the steering wheel, increase the clarity of the GUR operation, reduce the level of vibration of the hydraulic pump, protect the parts of the system from wear, when there is a low oil level in it. However, motorists belong to such additives in different ways. One they really help, others only harm and bring the replacement time of the pump GUR or holding it.
When choosing a fluid, pay attention to its temperature characteristics so that it normally worked with significant frosts (if necessary). Insofar as large-viscosity oil will create obstacles to normal operation of the GUR system.
Buzzing gur on hot
If the hydraulic is buzzing to hot, then there may be several problems. Consider several typical situations and methods for solving them.
- In the case when the engine begins during the engine warming, it is necessary to replace the pump or repair it using Repair Kit.
- When the knock appears on the heated engine on low revs, and at high disappears - this means that the gur pump comes into disrepair. The exit in this case can be two - replacing the pump and the fill of the more thick fluid into the system of the hydraulic fuel.
- If you poured counterfeit liquid into the system, it can lead to the fact that it is heated loses its viscosityAccordingly, the pump will not be able to create the necessary pressure in the system. Exit - replace the oil to the original, after having flushing the system (pumping with fresh liquid).
- Fault of the steering rack. When heated, the liquid becomes less viscous and can be seen through the glands, if they are damaged.
Remember that it is better to use the original liquid. This is evidenced by the experience of many car owners. After all, the purchase of counterfeit oil can cause expensive repair of the elements of the hydraulic system.
Gur buzzes in extreme positions
Do not turn the front wheels for a long time.
It should be borne in mind that when the wheels are turned until it stops, the Gur pump works with maximum load. Therefore, it can produce additional sounds that are not a sign of its malfunction. Some automakers report it in manuals. It is important to distinguish between emergency noises associated with problems in the system.
However, if you are confident that the sounds that have appeared are a consequence of a malfunction in the system, it is necessary to diagnose. The main reasons for the fact that GUR is buzzing in extreme positions are all the same listed above causes. That is, it is necessary to check the operation of the pump, the fluid level in the expansion tank, the tension of the drive belt GUR, the purity of the liquid. It is also possible that the situation described below.
Usually at the top of the gearbox is the valve box, which is designed to control hydrothotocks. When the wheel turns to the extreme position, the flow is overlapped by the bypass valve, and the fluid passes through the "small circle", that is, the pump works by itself and is not cooled. It is very harmful to it and is fraught with a serious breakdown - for example, bullying on the cylinder or pump chirates. In winter, when the oil is more viscous, it is especially important. therefore do not hold the wheels turned up to the stop for more than 5 seconds..
Buzzing gur after replacement
Sometimes the hydraulicel starts to buzz after replacing the oil. Unpleasant sounds can be caused by a pump in case of system oil was flooded less thickthan it was before. The fact is that between the inner surface of the stator ring and the rotor plates increases production. Also, the vibration of plates caused by the presence of irregularities of the surface of the stator.
It is also possible to occur the roast after replacing the high pressure hose of the hydraulic. One of the reasons may be a poor-quality hose. Some hundred sin the fact that instead of special hoses designed for high pressure and work in the GUR system, it establishes conventional hydraulic hoses. This may cause encourage system And, accordingly, the occurrence of the roast. The remaining reasons are completely similar to those listed above (a knock on the cold, hot).
In order for the hydraulicel to work normally and did not knock, you must adhere to a few simple rules:
- Monitor the oil level in the GUR system, in time to told and change it. In addition, check its condition. There is always a risk of buying a poor-quality liquid, which after a short period of operation comes into disrepair (check its color and smell).
- Do not delay for a long time (more than 5 seconds) wheels in extreme position (and left and right). It is harmful to the pump GUR, which works without cooling.
- When setting the car in the parking lot always leave the front wheels in the smooth position (right). This will remove the load from the system of the hydraulicer upon subsequent engine start. Especially this advice is relevant in the cold time when the oil is thick.
- In the event of (hum, knock, increased efforts when turning the steering wheel) do not pull with repair. You not only eliminate the breakdown with less cost, but also save your car, you and your loved ones from possible emergencies.
- Constantly watch out for the state of the steering rack. This is especially true of the state of anthers and glands. So you will not only extend the life of its service, but also save money on expensive repair.
Conclusion
Remember that when the slightest signs of the power steering fault, and in particular, the hydraulicel system, it is necessary to diagnose and repair work as soon as possible. Otherwise, upon the occurrence of a critical moment you risk losing control over the machinewhen steering refuses (for example, scan steering rack). Do not save on your car and security of your own and your loved ones.
Today, no car is required, the equipment of which was carried out with the orientation on the modern level of driving comfort. The hydraulic mechanism facilitates the physical control of the machine, while maintaining the optimal degree of feedback and compliance with safety requirements.
This is achieved by the introduction of auxiliary mechanism in the wheel, the technical condition of which should be regularly monitored. If, after a certain time of using the machine with such equipment, deviations in the operation of the mechanism are noticed, then it should be prepared for its repair. For example, if the steering wheel with a hydraulicer is tight, there may be several options for the output. But you must first consider the design of the mechanism and the principle of its work.
How is the GUR?
The hydraulicer system is multicomponent, but closed. Partly such a device and caused the complexity of the construction of the structure. The standard mechanism includes a pump, a tank with a tank liquid, a pressure regulator, a power unit and a spool. The pump connects to the drive engine of the machine, and the pressure regulator ensures the balance of the force consumption relative to the spool. The operating drop in pressure indicators depends on the reserve of the control fluid.
It is this part of the functional in most cases and leads to malfunctions, due to which it is required to repair the GUR in the form of correction of the position of individual parts of the design or by means of oil updating. In turn, the hydraulic cylinder interacts with translating additional effort. In order for the final load required to enable the steering into activity, the spool itself is installed on the column - in the future it will react to the rotational moment when manipulating the driver.
What grounds can be detected?
The feeling of gravity at the wheel does not always appear sharply and at one point. This may be a long process, during which warning signs may arise. In particular, the primary diagnosis will help to detect the problem on the formation of leaks, noise and excessive vibrations. Over time, the tight steering wheel is added to this list, if the same flow is not stopped, and the supply of fluid is replenished. Of course, the above features may indicate the emergence of other problems, and not only with the hydraulic agent. Therefore, the general diagnosis in this case will not be superfluous. It will make it possible to more accurately determine the possible cause of weighting of the steering wheel.
The main causes of the steering work
Factors that can lead to the difficulty of the steering wheel due to the hydraulic agent, a lot. Each of them involves its approach to repair. One of the most common causes is the presence of air in the hydraulic amplifier niches. Its presence does not simply level the main function of the mechanism, but also gives the opposite effect, taking the movement of the steering wheel.
Another frequent reason is the mentioned emptying of the expansion tank with liquid. If it was not possible to determine the reason why the steering wheel is spinning with the hydraulic feller, that is, it makes sense to refer to the technical condition of individual components of the system. For example, wear of parts, especially the drive belt, indirectly could provoke a decrease in the hydraulics function. In this case, it is not possible to avoid the complete revision of the mechanism and, possibly, its replacement. Do not exclude the probability of a problem in the steering itself. For example, the rail in parts of a bundle with a gearbox can deliver even more troubles in terms of repair.
How to disassemble a tight steering wheel?
To make sure the reasons for which the steering wheel action could occur, the mechanism should be disassembled. The event begins with disconnecting pipelines that lead to an expansion tank and steering system. At this stage, you can drain the liquid. Next, the drive belt is removed from the pump - again, if it is in an unsuitable condition, then new tape will have to wear.
Here, three block fixation blocks are unscrewed, suitable for a pump unit. But depending on the type of fasteners system, it can be more. After that, access to the elements of fixing the pump itself can be discussed. As can be seen, the repair of the GUR can be performed already at this stage, replacing the fluid by updating the hoses and the drive belt. But this may not be enough. Separate attention should be done with the filtering system. Even if it regularly performs its function, the violation at the purification phase is not excluded, which cannot be determined in the garage conditions. Therefore, if there are no other obvious causes a problem, it makes sense to check filters in a professional workshop.
Out of excess air
If the reason is to have excess air in the system, then in a sense you can talk about luck. True, everything is ambiguous here. Most often, this problem is solved by several rollers, communicated to the stop. And this action is performed in both directions. As practice shows, it allows you to push the excess air from the hydraulics communications. But if after this action is seriously spinning the steering wheel, then with a greater probability there was a trusting of the tank. This means that the system works with a liquid in which bubbles are present. This factor determines the absence of ease in handling the steering wheel. Eliminate this problem will help the full renewal of the fluid in the expansion tank.
Replacing fluid
This is not necessary to make a complete analysis of the mechanism. First of all, two nozzles leading to the expansion Baku should be released from the clamps. Also, additional fasteners and belt communications are removed if necessary, due to which access to the tank is difficult.
Immediately the replacement of the liquid can be performed and without completely dismantling the tank. The spent mixture is simply pumped up, after which it remains to pour out new auto chemicals. However, if the steering wheel is tightly spinning, which has not been checked for a long time, it is desirable to dismantle the tank for subsequent diagnostics. It should be checked for tightness, then rinse thoroughly and rinse with clean water. The dried tank is installed in its place, filled with a new working fluid and fixed fasteners.
What fluid is preferred?
The question of the choice of fluid for the hydraulic agent also imposes considerable responsibility. Preferred preferred synthetic hydraulic mixtures made of high-quality components. Normal machine oil is not suitable in this case. The peculiarities of specialized compositions include sufficient degree of fluidity, viscosity and ability of work at extreme temperatures.
Often, the problems of this kind are found in winter, when the flooded fluid is elementary not coping with its tasks due to the freezing. Therefore, the question of which oil in the power steering wheel should be poured, should be solved only in favor of special synthetic or semi-synthetic mixtures, which usually have a dark green shade. If we talk about manufacturers, the high-quality auto chemicals of this type are produced by Motul, Castrol, Pentosin, Liqui Moly, etc. The cost of liquid is about 800-1000 rubles, but even a small canister is enough for a long time, therefore it is not worth saving on this resource.
How to replace heavy steering wheel?
The dismantling of the system begins with the mentioned disconnection of all pipelines, nozzles and fasteners. Also, oil is mandatory or pumped out, covered in an expansion tank. Installing a new system is made in reverse order. If we are talking about the full update of the steering complex, then in this case you will have to dismantle the rack itself. This should be done in conditions where there is a mounting straight booth. The installation begins with the integration of the steering wheel, and then alternately integrated the components of the hydraulics. Lastly, the working fluid is poured, and elements of communication support are summed up.
Conclusion
By itself, the system of facilitating control of the steering wheel is quite complicated and often causes the problems with identifying the reasons for its incorrect work. If there is a tight steering wheel with a car hydraulic cylinder, which is quite possible that the problem will be in the not enough tires.
In this situation, the difficulty is already associated with the mechanics of the interaction of rubber coated, the effect of which is transmitted even on a good hydraulic. Also, insufficient tension of the drive belt may affect the function of the amplifier. That is, before proceeding with the repair work, the user must make a complete inspection of the car for the availability of factors that can affect the operation of the steering rack.
