Timing of gear oil change
from "Gear and Transmission Oils"
When lubricating enclosed gears, it is best to fill the correct quantity of oil of the correct quality in a hermetically sealed gear case. With this method of lubrication, the oil can not be changed during the entire service life of the mechanism. In particular, car manufacturers have chosen this path - in their manuals they do not indicate the exact dates for changing transmission oils, limiting themselves to a general recommendation on the maximum duration of their use.Therefore, to ensure reliable operation of the machines, as well as for economic reasons, it is necessary to drain the used gear oil from the gearbox housings and replace it with fresh one. The oil must be changed after oxidation or contamination, or at regular intervals.
Studying the issues of changing the oil in gearboxes, Forbes et al. Found that according to the operation of the gearbox in the first month of operation, they determine its service life; in the future, they suggested replacing or thoroughly filtering the gear oil two weeks after the mechanism was put into operation. This is also necessary because the smallest metal particles formed during the running-in process catalyze the oxidation of the oil.
Rejecting the arbitrary timing of changing oils, the authors mentioned above believe that it is most rational to periodically take oil samples to establish its further performance. First of all, the presence of dirt, wear products and water is determined in these samples. The acid number of the oil, viscosity and surface tension can also be determined. In some fleets of heavy-duty trucks, the oil used in gearboxes and drive axles is replaced with fresh oil after its viscosity has increased by 50%.
If gear reducers are equipped with circulating lubrication systems, then, according to Forbes et al., The oil can work for several years without changing, especially if there are appropriate filters in the lubrication system. It should be noted that cleaning the circulating lubrication system with an oil change is more time consuming than with splash lubrication. By adding special additives to flushing oils or using solvents, most of the deposits from the oil reservoir, oil lines and crankcase can be removed. However, after such flushing, the gearbox parts must be cleaned with a dry cloth.
After processing the gearbox housing with flushing oil, inspect its parts. If rust is found on the surface of gears and other parts, the reasons for their appearance should be investigated. If the gearbox parts are in satisfactory condition, fill the crankcase with fresh oil as soon as possible. In gear units with circulating lubrication systems, this can be done while the gear unit is not running. In dip-lubricated gearboxes, the gears are lubricated with oil prior to operation.
If the gear pair is made of dissimilar metals (for example, in worm gears), it is especially important to change the oil in a timely manner and inspect the mechanisms. After running-in, bronze particles adhere to the worm and make its surface rough, which increases the wear of the worm wheel. By changing the used oil and cleaning the worm from bronze soon after starting a new gearbox, further wear of the gears can be prevented.
If the lubricating oil is used once, it may not be necessary to flush the mechanism. When lubricating with oil mist, only fresh oil is supplied to the gearbox and the hermetically sealed gearbox housing is kept under a certain pressure, which excludes the possibility of contaminants entering the lubrication system. When operating open gear reducers, it is advisable to periodically clean them. In such gears, not only the residual oils are contaminated with various mechanical impurities acting as abrasives, while the cavities between the gear teeth are clogged with heavier oil components. If this continues long enough, skewing of the shafts may occur. These deposits can be removed by flushing the gearbox with kerosene or some other solvent and taking care when doing this. If there are oil collectors in open gearboxes, they must also be cleaned at regular intervals.
The main task of the oil in the gearbox is to minimize the abrasion of the gear wheels, in other words, to increase their service life. Poor quality lubricants, as well as untimely replacement, have a detrimental effect on the condition of the parts.
The replacement frequency is on average 50 thousand kilometers for cars with a manual transmission, and 30 thousand for an automatic one.
More often it is necessary to change the oil on cars, the operation of which takes place in difficult conditions, these include:
- Off-road driving;
- Constant maximum vehicle load;
- Frequent towing of cars or trailers.
In a new car, it is recommended to replace it after the first 2-3 thousand mileage. The fact is that at the initial stage of work, new units go through the so-called "lapping", in which an increased formation of wear products is characteristic.
Many car owners change the oil in the gearbox at the same time as the manual transmission, since transmission fluid is used in both units. 
Be sure to check the level and condition of the oil in the gearboxes after purchasing your vehicle from the aftermarket. Usually, if the owners change lubricants before selling, then only in those places where they can be easily checked. Gearboxes are not one of these.
Checking the level and condition of the oil in the gearbox
The level and condition of the oil in the gearbox is checked "for cold" when all the fluid is collected in the crankcase.
The oil should be at the level of the filler hole, 2-5 millimeters lower. To check, the filler plug is unscrewed and the level is recognized with a stick, wire, finger, or other improvised means. The condition can be checked here by taking a small amount of liquid with a syringe and tube. 
You can also assess the condition of the lubricant by unscrewing the drain plug for a few seconds. Tighten the filler first, so the oil will flow much more slowly. If the car has stood for several hours before, all foreign particles will settle in the crankcase, and you will get a clearer picture of the condition of the oil.
The presence of metal particles in the mining indicates that the gearbox assemblies have a high degree of wear, and serious repairs and replacement of parts may soon be necessary.
What and how much to fill
It is best to fill the gearbox with gear oil recommended by the manufacturer. The information is indicated in the technical documentation, and it is very important to focus on compliance with the API class.
Almost all modern car manufacturers require the use in their transmissions, gearboxes and dispensers of oils not lower than GL-4 and GL-5, which contain extreme pressure and other additives, and are adapted to work in the most severe conditions. 
If you do not know what kind of oil and how much is poured into the gearbox of your machine, look for it in the table. We have collected information on tolerances for various vehicles from many available sources.
If there are 2 or 3 axles in the car, then the total amount of fluid is indicated.

Change of oil
It is better to replace it after traveling a short distance (5-10 kilometers). This will allow the oil in the gearbox to warm up and become less viscous.
The car must be in a horizontal position, it is most convenient to work in an inspection pit, on an overpass or using a lift. This will make it easier to get to the gearbox. Use a metal bristle brush to clean around the fill and drain holes.
It will not be superfluous to pay attention to the condition of the oil seals, when worn out, oil can flow out of the gearbox. If you see smudges in the area of the oil seals, it is also better to change them right away.
To keep your car running smoothly, it needs constant care and maintenance. Of all the technical procedures, changing the oil in the rear gearbox is not the most frequent, but extremely important. A gearbox is a special gear mechanism that connects two axle shafts, which is responsible for converting engine power and transmitting it to the wheels. It allows the wheels to rotate at different speeds. Despite the complex design of the gearbox, changing the oil in the gearbox is quite simple with experience and skill.
How often should the gearbox oil be changed?
How often do you need to change the oil in the rear gearbox? It all depends on the car model and operating conditions. Experienced auto mechanics will say that under standard operating conditions, changing the oil in the gearbox is necessary on average every 40-60 thousand kilometers.
With intensive use of the car, over time, slow oxidation and decomposition of the filled oil occurs in the gearbox housing. The reason for this phenomenon is the ingress of heated air into an insufficiently sealed system. The inevitable decrease in oil viscosity during operation also has a negative effect.
Why do they pour m aslo in the rear axle gearbox? Timely filling of oil fluid into the rear axle gearbox is necessary in order to improve the interaction of the unit parts, to extend their operational period. Usually, car parts break down due to wear and tear, poor maintenance.
Prevention of malfunctions makes it possible to prevent the occurrence of various malfunctions in the unit. You need to understand how the oil is changed in the transfer case and the rear gearbox, to be able to choose which oil to pour into the rear axle gearbox.
How does the rear axle work, why does it wear out?
The rear axle reducer (transfer case) is a unit combined with each other that transmit torque from the power unit to the wheels. The gearbox is subjected to different loads, the degree of which depends on the speed. In view of this, friction appears in him, which has a destructive effect on his state. In order to compensate for this effect, a special lubricant is used to soften the movement of the moving parts and ensure their integrity. Changing the oil in the gearbox is an important procedure that must not be neglected.
It is necessary to change the oil in the rear axle approximately every thirty-five thousand kilometers. This replacement frequency is recommended by renowned car manufacturers. There are certain signs, upon detection of which it is necessary to immediately replace the consumable (having previously determined which oil to pour into the rear axle gearbox). These include:
- reducing the amount of car oil;
- the appearance of gray dust in the lubricant;
- change the shade of the consumable.
The influence of harmful factors on the rear axle of the car
A decrease in the amount of lubricant may be due to a deterioration in its technical characteristics, leading to a change in the viscosity index. Also, the level of the consumable may decrease due to the usual leaks arising from increased loads.
The appearance of gray dust is a sign of worn parts. The outer layer of spare parts wears off over time, precipitates. Getting into the car oil, the sediment begins to circulate throughout the lubrication complex. If it gets on an important part, its holes may be partially blocked. This could lead to damage. Pour fresh lubricant into the gearbox immediately if this problem is detected. If you find metal particles, shavings in the car oil, then you need to overhaul the engine and completely replace the damaged parts.
A change in the color of a petroleum product from gold to black is considered a sign that the lubricant is functionally worn out. Prolonged use, high loads, dustiness - all this gradually leads to a deterioration in the performance of the car oil. The molecular structure of the petroleum product is disrupted. Such oil is incapable of efficiently lubricating parts.
If you find at least one of the above symptoms, replace the oil fluid immediately. You can use the services of a car service. Its employees will replace the car oil in the transfer case in a short time. You will only need to pay them for the work. If you change the oil product yourself, you can save a lot (provided that the replacement is carried out correctly). However, changing the lubricant, it is difficult to make such a mistake that could completely disable the vehicle. The most dangerous thing that can happen is that you get burned with waste oil. If you are careful, this will not happen. You can save your money if you know how to fill the rear axle with oil.
Algorithm for changing the car oil in the rear axle gearbox
How is the oil change in the rear axle gearbox carried out? The algorithm is as follows:
Now you know how to change the oil in the rear axle of a VAZ (and any other car). Changing the oil in the rear gearbox is a fairly simple procedure.
Which car oil to choose?
What kind of oil to fill? It is possible to use both mineral water and synthetics. Due to its own composition, synthetics resist wear better than mineral water made through petroleum refining, which must be changed frequently. The advantage of mineral oil is its rather low price. Special additives are added to synthetics, which increase the operating period of such a car oil several times. However, the cost of synthetic consumables, especially from well-known manufacturers, is quite high.
Before deciding which oil to pour into the rear axle gearbox, remember that there are still semi-synthetic oil products. They are not as expensive as synthetic ones, while they have rather high technical characteristics (constant viscosity index, excellent lubrication performance). It is not for nothing that semi-synthetics have become so popular among many car owners in the Russian Federation.
Since the distribution box contains rubbing elements, wear products inevitably appear in it over time. If you do not change the oil in the transfer case in a timely manner, its resource will be reduced. Oil loses performance and small particles increase gear wear.
How often to change
There are several different types of transfer cases, and depending on the type of mechanism, the frequency of replacement can vary significantly. Usually this information is contained in the technical documentation for the car and varies in the range from 50 to 100 thousand kilometers.
In addition, the operating conditions affect the period. A distribution box for a car that drives on public roads experiences much less stress than that installed on a car that constantly moves off-road.
How to choose
Two types of fluid are poured into the distributor: transmission oil or ATF fluid. On cars with automatic transmission, ATF is usually poured into the transfer case, with manual transmissions - the transmission. In this case, often, the fluids must match, or be completely compatible.
This is due to the fact that usually the connection between the transfer case and the box is made by a single shaft, or one is attached to the body of the other. When mixing liquids, this will avoid the formation of emulsion, foaming and other side effects.
For most modern vehicles with a transfer case, the manufacturer recommends the use of GL-5 grade gear oils. They protect hypoid gears well, are designed to work in the most loaded mechanisms and contain extreme pressure additives.
The viscosity characteristics of oils play an important role. Let's analyze the meaning of the numbers using the example of 80W90 oil:
- 80 - viscosity at low temperatures
- W - all-season
- 90 - viscosity at high temperatures
If ATF is used, it is better to fill in the original fluid recommended by the manufacturer, or an analogue with appropriate approvals. 
What and how much to fill
The following table will allow you to choose oil by car make and find out how much is required.

Check level
On most cars, viewing windows are not provided for checking the oil level in the dispenser. Level control and replacement is carried out through the filler hole.
To check, it is necessary to place the car on a flat surface and unscrew the filler bolt, or the control bolt, if any. Usually they are made for four or hexagon, or for a wrench. 
A level just below the filler / control hole is considered normal.
The need for replacement is determined by the intake of a small amount of oil. This can be done with a syringe with a flexible tube at the end. Black, cloudy, with traces of depletion, must be replaced.
How to change
The replacement procedure itself is simple, but often complicated by the fact that access to the filler hole is difficult. A lift, viewing pit or overpass is also required.
Some motorists make their own drain hole in the distributor in order to facilitate the procedure for a complete oil change as much as possible. To do this, a hole is drilled at the bottom point for the plug and a thread is cut.
You will need:
- A special syringe for pumping technical fluids (cost 500-800 rubles). You can use a medical one, but due to its small volume, the replacement process will be significantly delayed. What is more expensive - time or money, you decide.
- Transfer oil (transmission / ATF) recommended by the manufacturer or having an appropriate specification.
- Gasket sealant, degreasing liquid.
To prevent dirt from getting inside the dispenser, you should clean the surfaces before unscrewing the plugs.
There is a drain hole
If your car is equipped with a drain plug, you need to unscrew the bolt and wait until the oil drains out completely. The magnet on the plug should be cleaned of debris. Degrease the drain hole and plug, apply a coat of sealant and screw the plug into place.
Using a syringe, fill the dispenser with oil until it flows over the edge of the filler hole, and then screw the plug onto the sealant.
No drain
In this case, all operations are performed through the filler hole. A syringe tube is inserted into it and the oil is pumped out as much as possible. The procedure for adding new oil is the same as described above.
