Transmission oil for the VAZ 2107 axle. Motor oils and everything you need to know about motor oils. Procedure for performing work when changing the oil

16.11.2021

Domestic car VAZ 2107 is a rear-wheel drive vehicle. The rear wheels are driven by the rear axle and cardan drive. An important role in this is played by the rear axle, which is a gearbox for converting torque from one value to another. This is the mechanism in which the gears rotate. Oil is used to reduce friction on these gears. What kind of oil is recommended to be poured into the rear axle gearbox of the VAZ 2107 will be discussed in this material.

The rear axle gearbox is a mechanism that is subjected to a number of different loads. Through these loads, destructive actions occur. To avoid accelerated wear of gearbox parts, it is necessary to use a special lubricant. This lubricant is an oil that, during the operation of the gears of the mechanism, envelops them, eliminating accelerated wear and overheating, and also cleans the teeth from chips and metal dust.

It is necessary to change the oil in the rear axle gearbox for the simple reason that over time it loses its primary properties. When the gears rub against each other, thermal energy is released, the value of which is reduced with the help of a lubricating fluid. In addition, when the gears rub, the teeth wear out, resulting in the formation of chips and metal dust. If you do not change the lubricant in the gearbox for a long time, the amount of metal shavings and dust will only increase, which will lead to accelerated wear of the rubbing parts.

When to change gear lubricant

Changing the oil in the rear axle of a VAZ 2107 should be done regularly, but there is no specific threshold. It all depends on many different factors, but the manufacturer domestic cars recommends performing this procedure every 60 thousand km.

Some of the main factors that influence the timing of oil changes are:

  1. Driving character. Frequent and abrupt starts are not at all beneficial to the parts and mechanisms of the car, including the rear axle.
  2. Vehicle operating conditions. If the car is used in rural areas where there are poorly paved roads, dust, and dirt, then replacement should be done more often.
  3. Lubrication quality. It is recommended to fill the rear axle of the VAZ 2107 with special high-quality oil. If you pour low-quality lubricants into the gearbox, you will need to replace them much more often.
  4. Operating a vehicle with a trailer. The wear of the device parts will accelerate if the car is operated with a trailer in which cargo is transported.

Features of lubricant selection

It is recommended to fill the rear axle gearbox of the VAZ 2107 with semi-synthetic gear oil. It should have viscosity parameters 75W-90. This is a universal lubricant option, which is usually poured into the gearbox.

Special gear oil in the gearbox improves the quality of parts and also reduces their wear. Not every G7 owner knows how much oil needs to be poured into the gearbox. The lubricant volume for the gearbox is 1.35 liters. It is poured through a special filler hole (on the side), using a technical syringe. You must first drain the old lubricating fluid, for which there is a special drain plug at the bottom.

Oil change step by step

The procedure for changing the oil in the gearbox is by warming up the old fluid; for this you need to drive the car for 10-15 minutes. After this, you need to go to the inspection hole, take necessary tools and materials, and go down. The replacement procedure involves performing the following manipulations:


  1. Washing the mechanism. This step is optional, since there are different opinions on the need to flush the mechanism. If there are chips in the drained liquid, it is recommended to pour flushing liquid into the bridge. To do this, you can use special liquids or use spindle oil. After washing or draining the liquid, you need to screw the drain plug back into place.
  2. Filling oil involves unscrewing the filler plug. This plug is located in the middle part of the bridge, at the rear. In order to pour oil into the bridge through this plug, you should use a special syringe. It can be purchased at the store. Fill the material until it begins to flow out of the filler hole. This is approximately 1.3-1.5 liters.
  3. Then all that remains is to screw the filler plug into place.

At the top of the bridge there is a breather. After adding oil, you should check its movement characteristics. It should move easily and without jamming. If the breather does not function, then when the lubricant in the gearbox heats up, it will begin to flow out through

Oil in the gearbox - all the mechanisms that rotate and rub against each other need oil, the same goes for the gearbox, inside it there are gears (They are metal) that rub against each other during operation and if they are not lubricated with anything, they will quickly come out (They will become scuffed or even deformed and the gearbox will have to be replaced), and when lubricated they will rotate and rub against each other with much less friction and therefore the wear of the parts will be reduced (They will not fail so quickly) , in addition, the gears in the gearbox will also work more quietly and thus it will not hum and vibrate too much as it will if you completely drain the oil and start the car.

How much to fill (volume)

You won’t believe it, but there are also owners who don’t even know that the rear axle of a car also needs regular lubrication, although not as often as the engine. Also, there are drivers who believe that if the oil does not expel or ooze, there is no need to change it at all. This is all wrong and it is also necessary to perform this procedure, as in the internal combustion engine and in the gearbox.

The lubricant volume should be 1.3 liters. To fill required level, you need to wait until the oil flows out of the filler hole, this will be considered the optimal volume.

Replacement

The oil is changed according to the same algorithm as the oil in the gearbox, after a mileage, so that the oil is hot and drains better:

- unscrew the filler plug

— place a container for used oil under the drain hole

- unscrew the drain plug

- after the oil has completely drained, tighten the drain plug

- pour oil into the filler hole until oil flows out of it

- tighten the filler plug

Which one to pour?

In terms of volume, 1.5 liters of liquid is sufficient for replacement. Change at intervals of 30-40,000 km or every 3 years, whichever comes first.

Most owners of the "Seven" fill the gearbox with transmission oil recommended by the manufacturer. In 2107, several types of gearboxes are installed at the factory. They all require high quality lubrication. Only in this case will the box work reliably and for a long time.

In the service book, the manufacturer indicates several viscosity levels:

  • SAE80W85,
  • SAE75W90,
  • SAE75W85.

Similar to motor oils, transmission oils, in addition to the viscosity coefficient, are divided into groups. In the VAZ 2107, professionals advise filling in:

  • GL-4,
  • GL-5.

The first group includes motor oils that contain a large number of special additives. This type is optimal for gearboxes with a large number of gears.

GL-5 brand oil is designed to lubricate rotating gears operating at a certain angle, that is, hypoid gears.

In the VAZ 2107, the rear axle gearbox has such a transmission. GL-5 is ideal for gearbox lubrication. The car manufacturer recommends replacing the lubricant in the gearbox together with changing the fluid in the manual transmission. Therefore, car owners use only one type of oil, pouring it into the box and gearbox.

In principle, no negative effect will occur. The properties of GL-5 allow it to be used in gearboxes. In addition, the compositions of this group were specially designed for use in extreme conditions.

Influence of viscosity grade

If the VAZ-2107 will be operated in temperate climate areas, where summers are constantly hot and winters are quite cold, then it is recommended to fill the manual transmission with transmission fluid all-season type - SAE75W90. It can operate in a wide temperature range (-40/+45). Moreover, the performance qualities of the oil always remain unchanged.

When purchasing lubricant for manual transmission, you must take into account your place of residence. Each region has its own climatic conditions.

For example, SAE 80W85 can be operated in the range from +35 to -26 Celsius. Some regions require a wider range, so it is important to consider these values ​​when purchasing.

Which oils are more suitable for the VAZ 2107?

In principle, any oil can be poured into the “seven”. The highest quality will, of course, be synthetic. Mineral water or semi-synthetic water will also not do any harm.

The cheapest is mineral liquid. However, it has a significant drawback - it begins to freeze quickly in cold weather. As a result, it is difficult to start the engine in sub-zero weather. You have to depress the clutch when starting the car.

Synthetics and semi-synthetics thicken less on cold days. However, their consistency is characteristic differences. Synthetics have high fluidity, which is why they are used in new manual transmissions. It begins to leak even with the smallest defect in the sealing gasket.

Semi-synthetic oil is thicker. Therefore, it is used in the manual transmission of a car that has covered more than 100,000 kilometers. If, after filling, the semi-synthetic material begins to ooze, then it is time to replace the failed parts.

Of course, each driver decides for himself which oil to use. But in any case, it is necessary to take into account all the nuances described above. Lubricant characteristics must comply with the manufacturer's recommendations. Replacement is carried out in accordance with the specified regulations. As a result, the gearbox will operate without repair for a long time.

Many VAZ 2107 car owners are interested in the question: how much oil should be poured into the main components of the car, such as the engine, gearbox or rear axle? In fact, this information is included in every vehicle operating manual that is issued upon purchase at a car dealership. But if you are the owner of a used vehicle or for some other reason do not know what the main filling containers important units, this information will be given below in more detail.

Required oil level in the VAZ 2107 engine crankcase

Absolutely all engines that were installed on the “classic” until recently have the same filling tanks. So, for example, the engine oil should be 3.75 liters. It is not always possible to mark this level yourself, since not every canister has a transparent scale. Therefore, you also need to navigate using the dipstick. Each dipstick has special MIN and MAX marks that indicate the minimum and maximum permissible level oils in the internal combustion engine. It is necessary to fill until the level is between these two marks, approximately in the middle.

Roughly speaking, when changing the oil in a VAZ 2107 engine, you will need a canister with a volume of 4 liters, since it will be drained almost completely. In many service stations, when refueling, auto mechanics fill the entire canister, since 250 grams do not play a special role, provided that they are more than the recommended value.

How much gear oil to fill in a classic gearbox

I think that every car owner knows very well that today there are VAZ 2107 models with both 4 and 5-speed gearboxes. Of course, the level of these two boxes is slightly different.

Of course, it is necessary to pour a little more into the 5-mortar for reasons that are understandable to everyone.

  • 5-speed gearbox - 1.6 liters
  • 4-speed gearbox - 1.35 liters

Capacity for filling oil into the rear axle gearbox of VAZ 2107

You won’t believe it, but there are also owners who don’t even know that the rear axle of a car also needs regular lubrication, although not as often as the engine. Also, there are drivers who believe that if the oil does not expel or ooze, there is no need to change it at all. This is all wrong and it is also necessary to perform this procedure, as in the internal combustion engine and in the gearbox.

The lubricant volume should be 1.3 liters. To fill the required level, you need to wait until the oil flows from the filler hole; this will be considered the optimal volume.

The most loaded unit in a VAZ 2107 car is the rear axle gearbox. But with proper assembly, installation and timely maintenance it can last longer than even less loaded units.
As the instructions indicate, the oil in the rear axle gearbox and gearbox should be changed after break-in, then after a run of two thousand kilometers and subsequently every sixty thousand kilometers.
The design of the gearbox of a VAZ car uses a special type of hypoid transmission with offset axes. This engagement reduces the noise level when grinding surfaces, but the sliding that occurs along the contact line of the teeth can lead to the risk of jamming.

Using special gear oil in the gearbox can eliminate it. The mixture contains extreme pressure additives, class GL-5.
This oil is called Hypoid.
The volume of oil poured into the gearbox is 1.35 liters. Changing the oil in the rear axle gearbox of a VAZ 2107 is carried out according to the same algorithm as the gearbox oil.
Replacement must be made before operating the car in winter and summer. For these seasons, the oil has a different viscosity.
In winter it is low, and in summer it is high.

Changing the oil in the rear axle gearbox of a VAZ

  • There is silver dust in the mixture. If there are metal grains instead of dust, this indicates serious damage to the car.
    You can't get by with just an oil change.
  • Coffee or black oil color. This indicates that water has entered it or the additives in the solution have been destroyed.
  • You can change the oil in the VAZ 2107 axle gearbox yourself.

Tip: The oil should be drained after the car has been driven so that it is hot and drains well from the crankcase. But you need to be careful, the temperature of the liquid can reach 90 degrees.

Work order

So:

  • Unscrew the plug in the hole for filling the oil with a key “17”.

  • Place a container under the drain hole to collect used oil..
  • Use a hex wrench to “12” to unscrew the drain plug to remove the used oil.
  • After the liquid has completely drained, the drain plug is screwed into place.

Advice: If the oil drained from the gearbox housing has a dark color or metal particles, the rear axle gearbox must be washed.

  • To wash, you need to pour in about one liter of a mixture of thirty percent kerosene with transmission oil. Instead of kerosene, you can use diesel fuel.
  • One rear wheel is lifted, first gear is engaged and the engine is started.
  • After three minutes, the washing mixture is drained.
  • For filling, it is better to use an oil blower or a lever grease gun. If you don’t have them on hand, you can use a large plastic syringe with an elastic tube attached to its end.
  • 1.3 liters of special transmission oil is poured into the gearbox.
  • It is necessary to ensure that its level reaches the lower edge of the filler hole.

After filling the oil, the breather is checked and cleaned of dirt. This device is necessary in order to relieve excess pressure in the gearbox that is formed when the oil heats up and when its level rises.
All operations for changing the oil on a VAZ 2107 car can be clearly seen in the video.

Steering of a VAZ 2107 car

On the VAZ 2107 model steering has a safety design with an articulated lever drive of the steering wheel and a worm-roller gearbox.

  • The steering mechanism gearbox is secured with three bolts in engine compartment on the left side member.
  • An adjusting screw installed on the top cover of the gear housing can be used to adjust the gap in the engagement of the double-ridge roller and the worm built into the structure of the device.
  • Approximately 0.2 liters of oil is poured into the steering gear housing.
  • To fill the oil, there is a filling hole on the top cover of the gearbox housing. There is no hole for draining the oil; fluid is only added to the VAZ 2107 if necessary.

Filling oil in the steering gearbox

Before adding oil, check the oil level:

  • The vacuum booster is removed.
  • Using a key set to “8”, unscrew the plug for filling oil into the gearbox, which has a conical thread.

  • A special rod is used to check the oil level. To do this, the rod is inserted all the way into the gearbox, as shown in the photo.

  • From the top edge of the filling hole, the oil level should be at a depth of 15 millimeters.
  • If you need to change the oil in the steering gear of a VAZ 2107, then use a spanner wrench to “13” to remove the four bolts that secure the lower cover of the gearbox.
  • Just slide the lid and pour the oil into the container.
  • The cover is put in place, secured with bolts and new oil is poured.
  • The plug is screwed into the filler hole.

Timely oil changes in the main components of the VAZ 2107 will increase its service life without costly repairs. And the price for oil changes is acceptable for all car owners.
