The main task of oil in the gearbox is to reduce the abrasion of gear gears as much as possible, simply put to increase their service life. Low quality lubricants, as well as unreasonable replacementAlways affects the state of details.
The replacement frequency is on average 50,000 mileage mileage for cars with manual gearbox, and 30 thousand for automatic.
More often it is necessary to change the oil on cars, the operation of which occurs in difficult conditions, can be attributed here:
- Driving off road;
- Constant maximum loading of vehicles;
- Frequent towing car or trailers.
In a new car, it is recommended to replace the first 2-3 thousand mileage. The fact is that at the initial stage of work, new nodes pass the so-called "wischable", in which the elevated formation of wear products is characterized.
Many car owners change oil in a gearbox simultaneously with the manual transmission, since the transmission fluid is used in both nodes. 
Be sure to check the level and condition of the oil in the gearboxes after buying a car on secondary market. Usually before selling the owners if they change lubricating fluids, only in those places where they can be easily checked. Reducer to such not belong.
Checking the level and condition of oil in the gearbox
The level and condition of the oil in the gearbox is checked "on the cold" when the entire liquid is collected in the crankcase.
The oil should be at the level of the filling hole, 2-5 millimeters below. To check, the filler plug is unscrewed and with the help of a stick, wire, finger, or other remedies, the level is found. The state can be checked here by taking a small amount of liquid with a syringe and tube. 
You can also estimate the lubricant state, unscrew the drain plug for a few seconds. Pre-tighten the fuse, so the oil flows significantly slower. If the car stood before that for several hours, all foreign particles will fall in the crankcase, and you will get a clearer picture of the condition of the oil.
The presence of metal particles suggests that the gearboxes have a high degree of wear, and soon it may be necessary to seriously repair and replacing parts.
What and how much to fill
Best of all in the gearbox to fill the transmission oil recommended by the manufacturer. Information is indicated in the technical documentation, and it is very important to focus on compliance with the API class.
Almost all modern automakers require to use in their transmissions, gearboxes and distributions of oils are not lower than GL-4 and GL-5, which contain anti-mailing and other additives, and are adapted to work in the most difficult conditions. 
If you do not know which oil and how much is poured into the gearbox of your car, look for it in the table. We have collected from many available sources information about tolerances for various cars.
If in the machine 2 or 3 bridges, then the total amount of fluid is indicated.

Change of oil
Replacement is better to produce after a trip to small distance (5-10 kilometers). This will allow oil in the gearbox to warm up and become less viscous.
The car must be in a horizontal position, most convenient to work in the observation pit, on the overpass or using the lift. So it will be easier to get to the reducer. Brushed with metal bristle clean the surface in the area of \u200b\u200bthe fuel and drain holes.
It will not be superfluous to pay attention to the condition of the salts, with the wear of which the oil can flow from the gearbox. If they can be seen in the area of \u200b\u200bthe glands, they are also better to change immediately.
Suspended boat motors have in their design nodes, some details of which are subject to wear as a result of friction. One of these nodes in the engine is a gearbox. To protect against wear of rubbing steam, a special is used.
Any grease during operation reduces its protective functions, so it is subject to replacement at a certain time. Replacement of oil in the suspended gearbox boat motor You can make a dealer. The procedure for changing the oil in the gearbox is simple, but requiring compliance with certain rules. Therefore, many motor owners produce a replacement of oil in the PLM gearbox independently.
Read our. Hard criteria! How to choose oil for a boat motor gearbox
The feature of the operation of the motors is such that the screw reducer works under water. The engine itself together with the gearbox has a water cooling system. That is, inside the engine along special channels circulates water, which comes from the reservoir and cools the parts heating from friction.
Despite the protection of the internal parts of the gearbox from the water with rubber glands and bushings, inevitably entering the water inevitably. Water, salt in seawater create a destructive environment for rubbing nodes, rust appears, corrosion.
Motor manufacturers recommend to apply special oils for a gearbox that have in their composition additives that bind water. Anti-emulsion additives confront the formation of emulsion, but their ability is not limitless. With a large volume of water, they will certainly not cope.
In oil, anti-corrosion additives may also be present, which do not allow rust and corrosion. Special effect they have during the operation of motors on the sea in salted water.
Transmis Zion oils used in gears and gearbox gearboxes do not have a set of anti-corrosion and anti-immulsional additives that bind water and protecting rubbing pairs from oil starvation. Applying their manufacturers of boat engines are not recommended. The benefit from the low cost can turn into expensive repairs of the gearbox.
Viscosity transmission oils, ensuring reliable operation of boat engine gearboxes, must match the SAE 80W-90 class. Stationary boat engines require oil with sAE viscosity 85W-90.
According to the API standards, transmission oils for boat engine gearboxes must correspond to the GL-4 or GL-5 class.
Oil aPI standard GL-4. Designed for lubricating conical and hypoid gears, which have a slight displacement of axes operating in variables in gravity conditions - from light to heavy. Usually contains half the volume of additives used for oils higher aPI class GL-5.
Oil API GL-5 Used for more loaded hypoid gears having a significant displacement of gear axes operating in severe conditions.
In this way, oil API. GL-5 have a greater number of additives, provide the best anti-facility properties, protect the rubbing surfaces under conditions of blows, high loads and pressures. That is, the GL-5 API oils completely overlaps the requirements of the API GL-4 standard.
Which oil is used for a boat motor gearbox
Oil according to SAE and API standards, which must be poured into a motor gearbox indicated by the manufacturer in the passport on the PM. In addition, for each engine brand recommended oil of a specific manufacturer.
Yamaha Motor Oil
Protection during the operation of the gearbox at high speeds, from corrosion, rust provides a set of additives contained in the oil. They provide long service life of motors. Oil film on the surface of rubbing units resistant to oxidation and high temperatures. Oil excludes deposits near seals, does not form foam.
Tohatsu Motor Oil
Tohatsu does not prefer some oil producer. In its motors gearboxes, you can pour oil of any manufacturer that meets the requirements of the API GL-5, SAE 80W-90.
Mercury Motor Oil
Mercury recommends for its motors exclusively oil Quicksilver, in the line of which 3 groups of transmission oils. PREMIUM oil is used for gearboxes of all types of suspended motors with a capacity of up to 75 hp. and corresponds to the SAE 80W-90 class.
Stationary MerCruiser engines, suspended motors With a power exceeding 75 hp, require High Performance oil. Mix these oils with each other forbidden. Oils contain a unique package of additives that reduce the appearance of emulsion when water gets into the gearbox.
How much oil in a boat motor gearbox
Motors of different power from producers differ from each other and the design of the gearbox. The higher the power, the more loads are experiencing the details of the gearbox. Since the dimensions of the gearbox increase with the power of the motor, then a greater volume of lubricant is required accordingly.
For example, for filling the oil into the tohatsu gearboxes up to 6 hp Requires up to 200 ml. Oils, up to 18 hp - 370 ml, 25, 30 hp - 430 ml, 40, 50 hp 500 ml, over 70 hp 900 ml already needed. Volume necessary oil Other manufacturers may differ slightly.
How to check the oil in a boat engine gearbox
To check the oil in the gearbox:
- we put the motor vertically on the stand or transom;
- we find on the left side of the gearbox the upper (control) hole, unscrew the cork;
- we insert the diploma into the hole, take it out, you can use a conventional match as a probe;
- if the probe is dry, pour oil.
How to replace the oil in a boat engine gearbox
To replace the oil, you will need:
- the container where it is necessary to drain the spent oil;
- wide slotted screwdriver;
- pads for traffic jams;
- special pump for pumping the oil of large volume if the volume of small oil is poured directly through the nozzle in the tube;
- new transmission oil;
- stand under the suspension boat motor, if the motor is not installed on the trans.
Sequencing
- We install the motor on the stand with the vertical location of the Deadwood. If the motor is installed on the translate, then the deydwood is also installed in a vertical position. Motor must be installed, slightly raising over the surface.
- Under the motor install the container For the drain of spent oil.
- We unscrew the bottom drain plug. The oil will begin to merge into the drain tank.
- We unscrew the top cork. We are waiting for the oil completely stalking from the gearbox (10 minutes). ATTENTION! Some "masters" after the oil drain recommend rinse with gasoline gearbox. In no case cannot be done. Gasoline destroys the glands, after which the water falls into the gearbox, forming an emulsion.
- Change gaskets on traffic jams (While the exhaust oil flows).
- Fill acquainted fresh oil In the gearbox. For refueling of small volume oil, special tubes (bottles) are used, which have a nozzle tightly inserted into the drain hole. If the volume is large, then apply special pumps. We insert the nozzle (tube) into the lower drain hole and squeeze the oil from the tube (we swing the oil with a large volume of large volumes).
- Oil pouring stop under the condition that oil began to flow out of the upper test hole, And it is little without air bubbles.
- Holding the tube (pump) tighten the top cork.
- As soon as possible to minimize the loss of oil we remove the tube (pump) from Nizhny drain hole and tighten the drain plug. A certain part of the oil will still flow. If the volume is small, it is not worth worrying.
- Check oil level, By revealing the top control hole. If there are a lot of oils, it is necessary to add it. Low level Oils can lead to the output of the gearbox.
- Tighten the plugs tightly. I wipe the oil from the gearbox. Exhaust oil transfer to special enterprises for further disposal.
One of the most important working conditions of the motor snow removal machinery - Properly selected and on time inside the oil. Let's study how to choose an oil for a snow blower, and how often it is changed.
What oil to fill in a snow blower - we understand in detail
When buying engine oil for a snow blower, such factors should be followed as the conditions for the technique and the properties of the lubricant. Since the unit is used in the cold season, often at temperatures -30 ° C, then the lubricant must have a number of specific characteristics. These include:
- Energy saving - from this property depends the speed of heat loss of oil in a preheated state. The higher the ability to energy saving, the better the means;
- A high degree of lubrication - oil protects the parts of the motor and other nodes of a snow blower from friction and wear. Therefore, the material must have a certain consistency in order to quickly penetrate the grooves between the gears of the mechanisms;
- Long service life - change motor oil In the snow blower, every month I do not want anyone. To get rid of this need, you need to choose a tool with an increased service life;
- Universality - Most. modern oils You can pour, both in gasoline and in diesel engines.
The modern market is literally shot by all sorts of brands of oils designed specifically for snow blowers. As part of such funds, there are all the necessary additives in the proportions necessary for the work. One of these lubricants is the 5W30 brand.
The marking of this lubricant denotes the extreme bottom freezing temperature of the means at -30 ° C, due to which the oil is well suited for operation in the northern regions of most CIS countries and Europe.
Another important element in need of lubricant is a gearbox. Its elements are in constant interaction, which is why permanent wear. About how oil pour into the gearbox, each specialist has its own opinion. However, all the requirements for lubricant material are reduced to the list of the most important parameters. These include:
- The inability to oxidation - the composition should not be oxidized and collapsed under the influence of cold temperature and atmospheric precipitation;
- Small flow - Motor oil for gearbox must have long time operation not to change it too often;
- Small evaporation terms - the lower the period of evaporation, the less you have to change the means;
- Slow wear at high loads - oil must have optimal additive proportions in order not to wear out.
It is worth noting that all the listed properties have more expensive oil for a snow blower reducer. But you should not be afraid of their prices - in practice, one bank of a qualitative means will cost an order of magnitude cheaper than several cans of cheap lubricants.
Replacing the oil in a snow blower - the right procedure
Snow removal oil should change in a certain order. If a snow removal Just put into operation, the first replacement of lubricant must be made strictly after 5 hours of operation. The second time it will have to change the oil in 25 hours. All subsequent material replacement procedures must be carried out every 50 hours of operation of the unit.
The algorithm for replacing the lubricant is as follows:
- To start a snowy cleaner, it is necessary to install on a flat surface;
- After that, the unit must be started and waited for 5-10 minutes - the heated oil becomes more dense and merges faster;
- Next, you need to drown out the motor and unscrew the plug at the bottom of the oil tank;
- After that, you need to pull the cover and probe from the neck;
- Then you should completely merge the oil from the tank, laying under it the container;
- Next, you need to spin the drain plug and pour fresh oil;
- In the end, it will remain screwing the dipstick and the lid and continue the operation of the snowpressure.
After replacing the oil, you need to start the engine motor and give it to work about 1-2 minutes. Next, the motor must be drowning and check the oil level in the tank.
How to fill oil in a gearbox - study the subtleties
Oil in the gearbox must be changed every 50 hours of operation of the unit. This can be done, as through a specially designated hole inside the node, so with the full disassembly of the element.
In the first case, the oil needs to be dialed with a syringe, then pour the means through the hole in the right or left part of the gearbox. The second option will allow not only to fill the fresh oil, but also to clean the mechanism from the remains of the old agent. To do this, unscrew the 4 fastening bolts and disconnect the two parts of the gearbox. The remaining old oil needs to be removed by an old cloth or a paper napkin.
After that, the gearbox must be deguted. To do this, you will need to handle the walls of the detail for removing varnish. In the end, it will remain to assemble the gearbox and pour new oil with a syringe.
The friction is a prerequisite in the work of machine components and mechanisms. But it, as a rule, has a negative side. The work spent on overcoming friction leads to wear of rubber parts, their heating, which causes a decrease in the efficiency of the mechanism.
And maybe therefore, from time immemorial, man leads a constant struggle against friction. Entries on the papyrus of the ancient Egyptians mention olive oil as a lubricant when erecting the pyramids. The axes of the chariots and the rubber parts of primitive weaving machines were lubricated with fat animals. And only in the 15th century, the Italian scientist and artist Leonardo da Vinci first tried to explore the laws of friction.
Today we cannot imagine any mechanism without such an important element as a lubricant. Lubricant Must reduce the strength of friction and meet the technical conditions of the operation of the aggregate. Lubricants are divided into liquid, plastic and solid. Liquid transmission oils are used in nodes with gear and worm gears for preservation of premature wear of parts, heat removal from the surface and decrease noise. Depending on the oil properties, the mechanisms can be operated at temperatures from -60 and up to +150 degrees.
In modern gearbox motor, various varieties of oils are used. Although the most widespread use industrial oils. The specific load acting in the mechanism and the speed of rotation of the gears are those two important parameters which are focused when choosing oils for motor gearboxes. Depending on this, it is a criterion for selecting the desired lubricated material.
Today, the range of transmission oils for motor gearboxes is very large. They can be both minerals consisting of oil distillation products and synthetic, vegetable or mixed. But the main and most important indicator of any oil is its viscosity and lubricated ability. The viscosity ensures permanent lubrication between rubbing parts and its thickness, and the presence of additives prevents premature wear.
In worm gearmotors, unlike gear, use more viscous oils, which contributes to an increase in resistance to the jamming. Lubrication occurs with a worm in the oil. Depending on the design of the gearbox, the filling with a lubricant is made by a syringe through a special hole or poured to the level of the control plug.
The last time becomes popular synthetic oils. They have higher stability when changing temperatures, resistance to erasure. And all this allows you to increase the intervals between the oil change.
To increase the operational reliability, the gear motor must not forget that the oil, filled into it, is an important element And it has a significant impact on the operation of the mechanism. After all, it is not for nothing that they say: you will not fool - you will not go.
To lubricate the engagement and bearings in gearboxes, various varieties of oils can be used: industrial, turbine, aviation, cylindrical, autotractor, motor, and oils with additives.
Wide use in gearboxes found industrial oils. The numbers in the design grade indicate the average viscosity value at a temperature of 50 or * 100 ° C.
Along with viscosity an important indicator Physico-chemical properties of oils are flare and frozen temperature.
In high-speed gearboxes, especially driven by steam turbines, turbine oils apply turbine oils in the gearboxes of turbocharging, turbocompressors and other similar machines for lubricating gears and bearings, turbine oil 57 (turboheduator) is especially widely used.
Turbine oils pass deeper purification compared to industrial and possess the following qualities: high resistance against oxidizing air action at elevated temperature; high diemulsing ability to quickly and completely separated from water entering the lubrication system; Low initial acidity and ash content. As a result, turbine oils are more often used in the circulating lubrication systems. Possessing high stability, they provide the opportunity long work without replacement.
Aviation oils have increased viscosity and oilyness, resistant to high temperatures. They are suitable for lubricating the transfer "both splashing and centralized stations.
Autotractor, transmission, motor and cylindrical oils possess high viscosity, increased outbreak temperature, some of them - reduced frosted temperature, are used to lubricate gearboxes of low circle speed.
Oils for industrial equipment "are used to lubricate large gearboxes in the metallurgical and mining and ore industries with gearing modules from 15 to 50 operating at speeds from 1 to 8 m / s. In winter time To reduce the resistance of the concentration of MAE PA in the pipes of circulating lubricating systems of oil P-8P, PS-28 is heated to a temperature of 20 ... 25 ° C.
Recently, industrial brands have been developed mineral oils With additives. Thanks to the rational percentage of additives, anti-wear, anti-promotional, antioxidant, anti-corrosion and other properties are improved.
Oil synthetic medium viscosity have low temperature Throy and can be used when working in low-temperature conditions.
Plastic lubricants in gearboxes are used to lubricate rolling bearings when oil splashing is not enough to lubricate. This takes place in multistage gearboxes when lubricating the bearings of low-speed shafts. Plastic lubricants can be divided into two group perverse and mortgages.
Pumping lubricants are used in centralized supply systems for pipes to lubrication points, as they have the smallest resistance.
Plastic lubricant Uniol-2 is recommended for centralized feeding systems. They have a temperature range of work in friction nodes from -30 to + 120 ° C and is characterized by higher operational properties compared with IP1 lubrication.
Plastic lubricant Lithol-24 and its ESH-176 substitute is recommended as mortgage lubricants and can work without replacing and additives up to 2 years at bearing temperature from -40 to + 100 ° C.
The choice of varieties and viscosity of the oil increases the viscosity of the oil is favorably reflected on the increase in the surface stability of the teeth. Therefore, more viscous varieties of oils are preferable. To lubricate the engagement and bearings of gearboxes, a large range of liquid oils is used depending on the working conditions and the circumferential speed.
The viscosity of the temperature characteristics of the oils. Preliminary selection of a variety of oil for lubricating the engagement of cylindrical and conical gearboxes, depending on the circular speed in the engagement and ambient temperature, can be performed by graphics.
For multistage gearboxes, medium viscosity oil is used, which is determined by graphics for each gear step. The viscosity of the oil for gearboxes, working reversible, should be 10-15% more found.
More accurately choosing a variety of oil is conducted at temperature ambient In the gearbox.
Many minerals liquid oils In reference materials, have a viscosity characteristic at a temperature of 50 "C.
