Flywheel is one of the main knots of the car. Its main function is the transfer of energy from the power node (engine) to the gearbox. The product is a multi-storey disc consisting of high-strength hardened metal. By appearance The flywheel is something like a gear, so finding it in the labor car will not be.
Purpose
As we said, the flywheel transmits rotation from the crankshaft car to the gearbox. But this feature is not the only one. The disk is able to effectively extinguish the crankshaft vibration and smooth out the work of the power site, preventing it detonation.
The flywheel makes it possible to automatically start the engine (without applying the handle curve). As a rule, when the ignition is turned on, the starter begins to rotate, which, in turn, turns a small gear. The latter turns the flywheel. And then the movement is transmitted by the crankshaft. Another feature of the "hero" of our article is the accumulation of kinetic energy, which allows it to be stuck during acceleration, and to give it to the process of stopping the vehicle.
But that's not all. It is due to the flywheel that appears to provide low level idle move, reduce the load on the power node and save the fuel in this way.
Main faults and reasons
Despite its visual reliability, the flywheel may also fail. At the same time, defects and their causes may be different. Let's consider the most common options:
- Damage to teeth or their natural wear during operation. The reasons for this phenomenon can be somewhat - the technology is broken during the assembly process, is defective (worn) the starter, the extraneous "trash" in the flywheel carcarer. In such situations, you can install a new toothed crown, adjust or repair the starter, restore the wiring.
- Flywheat beats appear. The reasons for this problem include disruption of working capacity or the natural wear of the clutch, the appearance of its slip, long-term operation (natural wear), coarse errors when assembling. If such problems occur, it is necessary to check the strength of the beats. If the problem is insignificant, then you can limit the surface processing on the lathe. In the case when the beating is very strong, then installing a new or repair of an old clutch is required.
- Broken surface. The reasons are the same as in the past case. Exit from the situation is the installation of a new flywheel, adjustment or clutch adjustment.
- Violated the integrity of the landing site under the flange of the crankshaft. To this can lead long work Motor or errors in the assembly process. In this case, change the flywheel, check and (if necessary) change the crankshaft. With the required moment, stretch the fastening bolts fixing the crankshaft and flywheel.
- Violated (or worn during operation) carving under the bolts. This could cause mistakes in the installation and long-term operation of the car. Here is the best way out - replacement of the flywheel. But if possible, you can cut a new thread and carry out balancing. By the way, the last work is very laborious and does not always allow to achieve the desired result.
Features of the replacement of the flywheel on the VAZ-2101-2107
So, when serious problems (We described them above) You decided to establish a new flywheel. There are two options - to trust the masters for a hundred or do everything yourself. We will look at the budget version - independent replacement. And indeed, why do you exercise additionally, if there are no difficulties in such work?
Act in such a sequence:
- Prepare to replace the flywheel tool. Everything that will need is dynamometric Key, screwdriver (preferably it is with a thick tube) and set of end keys.
- Remove the gearbox. Otherwise, the flywheel will not get to the flywheel.
- Remove the clutch casing from the flywheel. Together with them, remove both disks (push and slave).
- Securely fix the flywheel using a powerful screwdriver so that it does not turn.
- Remove the six disk mounting bolts.
- Remove the flywheel (after removing the bolts, it should easily get out of the shaft). When removing, hold the supporting washer (set it out until the sideline). Please note that a special label is applied on the flywheel, the location of which must be remembered. When installing a new node, make sure that the label is in the same place (this is a very important point).
- Put a new flywheel and make sure that its label is in the correct position.
- Put everything on the place in the reverse order - screw the flywheel bolts, wear the clutch casing and return to the place of the checkpoint. Special attention is paid to pull bolts - they must be twisted not one after another (as many newcomers make), but "cross on a cross." This approach avoids the random skew of the flywheel.
In the process of installation, be sure to consider some recommendations:
First, in the process of removing the flywheel, try not to put the crankshaft of the car. Otherwise, you will add work;
Secondly, if the crankshaft is still shifted, put the 4th cylinder piston into the position of the top of the dead point.
After the piston was put in the upper dead point, the flywheel put an exclusively tag up (you can no longer focus on the previous sketches).
Output
Many beginner motorists for some reason are terribly afraid of work on the replacement of the flywheel. But there is nothing complicated here. The most time consuming part of the work is the removal of the checkpoint. But here the main thing is attention and clear compliance with the instruction manual. All work takes no more than 2-4 hours. At the same time, 3-4 thousand rubles can be saved, which will definitely ask for a hundred. The main thing here is confidence in its forces, utter attention and a clear adherence to the proven time algorithm. Good luck.
When an extraneous noise occurs when the engine is often required to replace the flywheel. This procedure should be carried out in compliance with a number of recommendations.
Replacing the flywheel in the car may be required for a number of reasons, for example:
- in running;
- after a frequent change of clutch components;
- as wearing.
In this case, you can notice some signs of the malfunction of this part, for example, extraneous sounds when starting and stopped the engine. If such signs appeared, it is necessary to diagnose, repair or replace faulty elements, the device you want to know to correct faults.
In order to deal with the replacement procedure, the problem situations that may occur during the operation of the flywheel should be examined.
You can select multiple types of faults that occur when it is functioning this engine element.
First defect: wear and / or damage to the element gear
Causes of fault:
- wearing and / or breakdown of the starter, its individual elements or nodes;
- incorrect installation of the starter in the flywheel card;
- ingress of foreign particles in such a device like a flywheel carder;
- errors during construction assembly;
- the flywheel's gears is worn out during long operation Engine.
Progress:
- the flywheel gears must be replaced;
- the correct installation of the starter in the flywheel card;
- checking the starter work and its repair, if necessary.
Defect Two: Flywheat Battle
Causes of fault:
- clutch slip;
- natural wear of the component with long-term operation of the engine;
- build errors.
Progress:
- checking;
- with a small beyon - processing of surfaces by means of a lathe;
- with a large biogen - change parts;
- checking the functionality of the clutch, its repair and shift if necessary;
- checking the operation of the clutch shutdown and its repair, if needed;
- exercise proper delay Fastening bolts, it must be observed right moment - Approximately 100 N * m.
It is worth noting that the allowable value of the beyon must be installed by the manufacturer, it can be found in the appropriate directory. At the same time, you need to know what role the excess of this magnitude can play.
The beating can provoke damage to the working surfaces by which the slave clutch disc is functioning.
At the same time, the car owner may notice some signs of malfunction when the engine is running. When correcting malfunctions, it is necessary to observe the correct torque of tightening the fastening bolts.
Defect Third: Violation of the functionality of the working surface under the slave clutch disc
Causes of fault:
- wearing or breakdown;
- clutch slip;
- the device is worn at long-term operation of the engine;
- errors when assembling the part.
Progress:
- replacement of the element;
- check, repair and change of clutch if necessary;
- check and repair clutch shutdown as needed.
It is worth noting that the functioning of the element with a broken clutch can lead to the warming of the working surfaces of the flywheel, as well as to the formation of cracks.
These signs can be found during diagnostics.
Fourth defect: damage to the landing place under the flange of the crankshaft
Causes of malfunction
- the device is worn with long engine operation;
- detail assembly violation.
Progress:
- replacement details;
- checking, repair and replacement for the needs of the crankshaft;
- the correct setting of the crankshaft in the flywheel carter;
- proper assembly technology;
- implementing the proper tightening of the bolts of fastening the element to the crankshaft, and the correct moment must be observed.
When carrying out troubleshooting work, you must comply with the correct moment of tightening the fastening bolts.
Defect Fifth: Malfunction and Wearing Threads Holes Designed for Fastening Bolts
Causes of fault:
- violation of the assembly Details: incorrectly located or fixed the hook of the flywheel;
- the device is worn with long engine operation.
Progress:
- replacement of the element;
- drilling damaged threads, cutting new, if possible;
- checking how the flywheel casing is fixed, corrected with incorrect position;
- balancing details.
It is worth noting that with any actions that are associated with the replacement of the element, it is mandatory to carry out the balancing of the crankshaft assembly with the disk and flywheel, after which it can be used.
This plays an important role in the subsequent correct work of all the details. It is also necessary to check whether the flywheel cover is located correctly and is fixed.
Procedure when replacing the element
When replacing the item, you must first remove the part. At the same time, it is necessary to navigate the following actions algorithm:
- Remove the gearbox in the car.
- Remove the flywheel casing simultaneously with the slave and pressure disk.
- The fixation of the element with a screwdriver, while it will not turn into the bolt turning.
- Turning six bolts fixing flywheel in engine internal combustion. They should turn the cross-crosswise, which significantly facilitates the task.
- Remove the element and support washer. At the same time, you need to remember the position of the flywheel relative to the observation mark.
Installation of the new design is also carried out in stages:
- Installing a new part in the same position, in which the previous one was installed.
- The installation of all the remaining elements is in order to remove, while you need to pay attention to the fact that the woven cover is correctly located, and the moment of tightening the fastening bolts was within the recommended values \u200b\u200b..
It must be borne in mind that the fastening bolts of the element should be tightened evenly, crosswise, after which it is necessary to check how the item itself is standing: after the tightening there should be no distillation and slopes, so that the wear is not rapidly. When tightening the bolts, the correct point should be observed - approximately 100 N * m.
After the removal of the details cannot be wrapped the crankshaft, because at the same time installing a new design may be difficult. But if all the same crankshafts have been turned, you need to install the cylinder piston number 4 to the upper dead point position, after which you should install a new part to your place according to the location of the tag. For proper installation and the operation of the element in the engine The duration of its trouble-free operation will be longer, the signs of faults will not manifest itself, and the repair will not be required for quite a long time. It is important to correctly spend all stages of work - from removal old detail Before tightening fastening bolts. Also worth paying special attention At the time of tightening fixing bolts: it should be approximately 100 N * m.
The flywheel of the internal combustion engine serves to accumulate energy. It helps the pistons to pass the bottom dead points (especially when starting the engine). The flywheel transmits the engine torque on the checkpoint. There are three types of flywheels:
- normal;
- lightweight;
- dampfer (in the damper inside the springs are installed).
The resource of the flywheel is usually 120-150 thousand km. It all depends on how intensively and in which modes the engine worked. Typically, the installation of the new flywheel is performed after the wear of the two sets of clutch friction linings, so the flywheel is validated with the clutch.
Repair of Makhovika
Frajects flywheel are obvious. This item is experiencing constant dynamic loads and friction, which leads to physical erasing of contact surfaces. As a result, vibrations or beats appear, the clutch can "slip". Simple flywheels are subject to replacement, damper is restored in special workshops.
One more typical malfunction It is damage or wear of the seashest. If the flywheel is still working, the crown change, if not, change the entire knot entirely.
With the repair of damper flywheels is more difficult. They are repaired and restored in specialized workshops. Defecting, accurate measurements, balancing machines, Professional welder services. The essence of the process is that the worn surfaces are grouped, the springs and the sliding bearing are changing. Flywheel balancing and experienced under load. After repairing the plane of the flywheel must "fall" into the admission of backlash and beats.
Replacing flywheel
For replacement, car shift, a transmission rack and standard instruments for fitter work will be required.
Replacing flywheel VAZ 2106
Engine classic Zhiguli. It has an ordinary single-mask flywheel. Consider how to remove the flywheel and the technological sequence of its replacement:
- First you need to access the flywheel. If the engine is removed, there will be no problems if not - you need to dismiss the gearbox and the clutch basket;
- Next you need to keep the flywheel from turning. For this, a special retainer is used, but a conventional screwdriver is suitable;
- After removing the checkpoint, you need to unscrew six fasteners bolts, then we remove the flywheel;
- Installation of new flywheel . Mounting the flywheel to perform in the sequence, reverse dismantling. Flywheel bolts are dragged to a cross on a cross with an effort 60.1-87.4 N.M.
Remove flywheel
Welcome!
Engine flywheel - this one of the most important details in the design of the car engine and therefore, with a strong wear of the flywheel, or when it is wrong, the car starts to start "busting - it is meant that when driving from a place or when driving, turnover The engine will jump and the car itself accelerates at the same time, but will not be roar. " Therefore, the flywheel must be changed in a timely manner, as riding on the worn will take pleasure and only bring discomfort.
Note!
To replace, you will need to stock: scold, as well as a M-shaped end key and, if possible, take a dynamometric key with you!
When to replace the flywheel?
It is subject to replacement when:
How will the car behave with a worn flywheel?
- As noted earlier, the first thing will most likely be, so this is the fact that the grip will be stopped by a worn flywheel.
- As well as most likely when attaching from the place, the car is touching, but it will be accompanied by strong vibrationwhich, as a result, will be transmitted to the entire car.
How to replace the flywheel on the VAZ 2101-VAZ 2107?
Removal:
1) To start, remove the transmission from the car. (On how to remove the gearbox, see the article called: "Box Replacing")
3) Next, fix the flywheel with a screwdriver, so that it does not turn the bolt when turning off the bolts. After fixing using the end key, unscrew all six flywheel mount bolts to the car engine.
Note!
Turn the bolts cross the cross, because it will be much more convenient!
4) Now remove the flywheel itself and, together with the flywheel, remove the support washer.
Note!
When you remove the flywheel, be sure to look at it. (Be sure to read the item "", at the bottom of the article)
Installation:
1) At first, install a new flywheel in the same position in which the old one was standing. (Position this by tag)
2) Then set all the remaining parts in the reverse order.
Note!
When your business gets before tightening the fastening bolts, the flywheel, then tighten them evenly, the cross on the cross. And when all the bolts are tightened, check how the flywheel is worth any slopes and there should be no distillation, and otherwise it will lead to its rapid wear!
Important!
After removing the old flywheel, try not to turn the crankshaft and otherwise the installation of a new flywheel may find it difficult.
Note!
But if you still tested the crankshaft, then in this case, set the fourth cylinder piston to the "NTT - upper dead point" position! (On how to install the piston in the "upper dead point", see the article entitled: "Installing the fourth cylinder piston in the NMT position")
After the piston is installed, the new flywheel is installed on your place, strictly vertically tag up and in any way!
