How much is poured into the bridge on the VAZ 2107. Oil into the gearbox: check and replacement, how much and what kind of oil to pour

The VAZ-2107 rear axle gearbox is a complex device with the help of which the crankshaft revolutions are converted into the rotation of the rear wheels. The drive axle is attached to the car body with rods. For reliable operation of the gearbox, a filling is provided, which protects mechanical parts from premature wear. This device operates under high temperature fluctuations and constant high load. Therefore, to protect surfaces, a special oil with increased protective properties is required.

The rear axle often operates at high temperatures (around 140 degrees). Under the influence of air, the composition is oxidized lubricating fluid, clots, sediment are formed, viscosity decreases. As a result, the protective lubricant becomes useless. And the details of the drive axle are destroyed. Changing the oil in the rear axle of the VAZ-2107 can significantly extend the life of the vehicle.

The design of the VAZ-2107 gearbox is a hypoid transmission with offset axles. This structure reduces the noise performance during grinding of the parts of the mechanism. But at the same time, additional sliding can cause the knots to jam. A good lubricant prevents this kind of malfunction.

When you may need a replacement

The grease loses its properties over time. Change the oil in the bridge regularly, according to the instructions. But during operation, signs of malfunctions may appear, which signal the need for a faster change of the spent fluid:

• appear from the side of the bridge;
• when the nature of the load changes, knocks are heard;
• there are drips and traces of oil liquid on the gearbox.

The car care instructions state that in the VAZ-2107, the rear axle oil is changed for the first time after running in (2000 km.). And then it needs to be changed every 60 thousand kilometers. But, given the harsh climatic conditions with ultra-low temperatures, bad roads and constant driving in city traffic jams, it is recommended to fill in the new oil after 30 - 35 thousand kilometers. Unscheduled maintenance when buying a used car, overhaul are also accompanied by the replacement of the lubricant.

Experts advise changing the lubricant in different seasons (winter and summer). In winter, the oil composition should be more liquid, with a lower pour point. And in summer it is more viscous.

Checking the oil level

Oil change instructions

You can change the lubricant of the gearbox on an inspection pit, overpass or lift. Before driving the car into the hole, you should drive a little and warm up the bridge fluid. You should also prepare in advance a tool (a set of keys and screwdrivers), a container for testing, protective gloves, a rag, a special syringe or a device with a hose for filling.

Changing the oil in the gearbox of the rear axle of the VAZ-2107 is carried out in the following order:

1. Clean any dirt from the drain and filler plugs.
2. Unscrew the drain plug with a 12 key.
3. Drain the old transmission oil in the prepared container. Remember that the liquid will be hot after warming up.
4. Tighten the drain plug.
5. Unscrew the filler plug.
6. Pour in just enough oil to reach the bottom of the hole.
7. Tighten the filler plug. Check for leaks.

If inspection of the used fluid shows heavy contamination, then flush the gearbox before filling with a new one. For this, gear oil or engine oil is mixed with diesel fuel in a ratio of three to one. The resulting mixture is poured into a gearbox. One wheel is lifted by a jack. The engine starts, the first gear is connected. This process takes several minutes. After that, the cleaning liquid can be drained and refilled with the drive axle.

Oil in the gearbox - the whole mechanism that rotates and rub against each other needs oil, the same with 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 of in order (they will have scuffs or even deformed and the gearbox will have to be changed), and when lubricated, they will already rotate and rub against each other with much less friction and, therefore, the wear of parts will be reduced (They will not fail so quickly) , in addition, the gears in the gearbox will still work quieter and thus it will not buzz and vibrate too much, as it will be if the oil is completely drained and the car is started.

How much to fill (volume)

Believe it or not, there are some 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 those drivers who believe that if the oil does not drive out and does not ooze, then it is not necessary to change it at all. This is all wrong and this procedure is also mandatory, as in the internal combustion engine and in the checkpoint.

The amount of grease should be 1.3 liters. To fill the 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 the run, so that the oil is hot and better drained:

- 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

What 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.

Conduct change of transmission oil v gearbox (Checkpoint) and rear axle reducer recommended every 35,000 km or after three years of vehicle operation. Also, you can advise to check the level and condition transmission oil immediately after buying a used car. The oil should be changed if: oil in the crankcase Checkpoint and reducer below the recommended level, there is silvery dust in the oil (it is dust, if you find metal grains in the oil, then it is probably too late to change the oil and it is necessary to prepare for a serious repair), the color of the oil is black or coffee (which may indicate the destruction of additives in oil or if water gets into the oil). And, of course, an oil change in Checkpoint, and in rear axle reducer you can do it yourself! How to do this and what you need for this, read on ...

Change of transmission oil in the gearbox and gearbox it is best to spend at the same time and immediately after the trip (at least 5 km for the oil to warm up). Plus, you can immediately buy 3 liters of 80w90 oil - 1.3 liters in the gearbox and 1.4 (1.6 in the five-speed) liters in the gearbox and there will still be left for lubrication of locks, etc.

Further ... It is better to change the oil at the inspection pit or overpass. And most importantly, what I want to say right away. The oil filling phase can cause a problem. rear axle reducer and especially in gearbox ... For this, an oil blower (photo 1) or a lever grease gun is best suited. But, since these devices may not be at hand, you can replace them with a large plastic syringe plus an elastic tube tightly fitted at its end. Still, for filling oil in the gearbox you can use the design - a long rubber hose (one end of the hose is in the gearbox, the other is brought up into the engine compartment) and a watering can (inserted into the end of the hose that is brought out into the engine compartment). The only disadvantage of this method is that it is necessary to warm up the oil or replace it in the summer.

Tool: ring wrench on "17", hexagon on "12", container for draining old oil.

We change the oil in the gearbox VAZ-2101, VAZ-2102, VAZ-2104, VAZ-2105, VAZ-2106, VAZ-2107 :

1. First we unscrew the drain plug (photo 2K) (usually a “12” hex key) and drain the oil into a previously prepared container. After that, you can unscrew the filler plug (photo 3K) (key to "17").
2. Let the oil drain well and wrap the drain plug.
3. We choose one of the injection methods (oil blower (photo 4K), a large syringe or filler funnel plus a rubber hose) and pump the gear oil to the lower edge of the filler hole (in general, fill it until it flows). And we twist the cork.

We change the oil in the gearbox of the rear axle VAZ-2101, VAZ-2102, VAZ-2104, VAZ-2105, VAZ-2106, VAZ-2107 :

The procedure for changing the oil in reducer the same as Checkpoint, only the photos are different.

1. Drain plug on the rear axle gearbox (photo 2P).
2. Filler plug on the rear axle gearbox (photo 3P).
3. Fill the gearbox with gear oil up to the lower edge of the filler hole (photo 4P).

If the oil is in reducer or Checkpoint heavily contaminated, then the crankcase should be flushed Checkpoint or reducer... For this you need to mix transmission(motor can be used) butter with diesel fuel (proportion, about 30% of diesel fuel). Pour into Check point (reducer), jack one rear wheel, start the engine, engage first gear and let it run for 3-4 minutes. After that, you can drain the flushing mixture and fill in fresh transmission oil.

Changing the oil in the rear axle gearbox on the VAZ 2101-VAZ 2107

The oil in the gearbox with the whole mechanism that rotates and rub against each other requires oil, the same with the gearbox, inside it there are gears (They are iron) that rub against each other during operation and if they are not lubricated with anything, they will quickly come out of system (They will appear on their bully or generally deformed and the gearbox will have to be changed), and when lubricated, they will already spin and rub against each other with even the least friction, and in this regard, the wear of parts will be reduced (They will not fail so quickly) , in addition to that, the gears in the gearbox will still work quieter and so it will not buzz and very very vibrate as it will be if you completely drain the oil and start the car.

To make an oil change, you need a minimum of tools and a minimum of time, so from the tools it comes in handy: A wrench about "17", as well as a hexagon, stock up somewhere "12", respectively, a rag is useful to clean the drain plug from all the dirt, well and the oil itself, so by the way, about 1.3 liters of transmission oil enters the gearbox (a container for draining about 2 liters.

Where is the rear axle gearbox located?

It is located in the rear central part under the bottom of the car, there is also a cardan gear (some call it a cardan shaft) passes and connects to this gearbox itself, in the photo below you can clearly create a gearbox because it is circled in a circle, there are two more plugs on it. are necessary just for filling the oil (This is the filler plug is indicated by a reddish arrow) and for draining it (This is the drain plug is indicated by the blue arrow), remember them right away, since as we read the article, we will not indicate them in the photo, but just say unscrew the filler plug, turn off the drain, because you need to know their location.

When do you need to change the oil in the rear axle gearbox?

There is no specific threshold in oil change, because they have different properties from different manufacturers, someone claims that the oil in general should never be changed (There are a lot of statements about the fact that butter does not need to be changed, it concerns the control gear, in fact, everything wears out over time and must be replaced) but each oil has additives, thanks to which the gears wear less, and their anti-corrosion characteristics are also in their anti-corrosive characteristics so that the gears do not rot, therefore, after a certain threshold, the oil 100% will have to be changed, which with regards to rear gear of the bridge, then the oil in it is replaced by 20,000-40,000 thousand km. mileage, depending, as we have already said, on the properties of the oil, in addition to the operation of the car (where it drives), you also need to look, for example, if you live in a rural area where there is only dust and dirty road surfaces on which you have to skid in the rain, then butter in this case, it is necessary to change more often, this also applies to cars that drive and brake at a short distance and then move again (in the town, so many cars drive, standing in traffic jams at all times) and most quickly the oil becomes unusable when driving at high speeds ( Since the engine turns a lot there) and when pulling various kinds of trailers.

Apart from the things listed above, the oil also needs to be changed after its expiration date (it is indicated on the box and is equal to approximately 5 years) because during this period of time all its characteristics and additives are lost and the oil cannot be called oil after that, it's simple stupid liquid becomes, by the way, there are also unscheduled oil changes that must be performed when buying a used car (Of course), immediately after running in a new car (It's just that new cars are filled with oil, which is only enough for a short-term filling, they save so well, and even more so after oil must be changed, because all the parts are lapped and during lapping they wear out a little and all their wear and tear must be removed by changing the oil) and this also applies to old cars, because if you installed a new gearbox, for example, after running it in (2.500- 3,000 thousand km.), The oil must be changed in order to remove all iron shavings from new gears (Wear products are so to tell)!

By the way, when installing a new gearbox, if you changed it, then after pouring the oil, we advise you to ride it for almost 50-100 km and then drain the oil into a clean container and let it brew for a month or two (This should be looked at by how muddy sediment 100% reincarnated) and then it can be filtered and used again, and it is necessary to drain through such a small gap of time, since there will be dust and dirt on its walls inside the new gearbox, and you will remove all this dirt with a short-term oil change!

How to change the oil in the rear axle gearbox on a VAZ 2101-VAZ 2107?

1) First, the oil must be warmed up, the heated oil flows out faster, as well as all the dirty particles from the inside of the gearbox crankcase peel off and mix with the oil, so you will pour out all the oil and all the dirt that is on the walls of the gearbox crankcase (Gearbox crankcase this is the place in which the oil is located), in order to warm up the oil, start the engine near the car and let it run for a while, as the engine temperature arrow shows the operating temperature, finish warming up and turn off the engine near the car, at this moment the oil in the gearbox will heat up to a sufficiently high temperature (approximately 75-90 degrees), so be careful not to burn yourself when you drain it.

2) Now stock up on some kind of iron brush and wipe the filler plug and drain from dirt with it, you don't need to do this, but if there is a brush under your hand, then follow the advice, after this operation, unscrew the drain plug and when you feel that the plug is already here now it will unscrew, put the hex wrench aside and use your hand to unscrew this same plug as shown in the photo below, note that after you unscrew the plug from the hole that it closes, oil will pour out, so prepare an empty container for draining right away.

If you want to thoroughly pour out all the oil and all the dirt from the gearbox, then raise the slightly right rear part of the car with a jack, so the car will fall on the left side (In the direction of the car's movement) and all the oil will merge better from the gearbox, because the drain holes are located not directly at the bottom, but a little from the side (you can create this in the small photo below)!

3) Next, wait until the oil is all drained and wiping the drain plug dry from all the dirt (wipe it on the inside, you can not wipe it on the outside), turn it into place, then pay attention to the oil drained from the gearbox, it should not be obvious iron shavings (if there is, then this is very bad, in this case, change your own driving style because the gears in the gearbox do not withstand such loads and crumble a little, or just change the oil on time), silver dust may be visible, but this is also not very great but better than the obviously visible iron shavings, and if your oil has combined coffee, this may indicate that the gearbox on your car is not sealed and water gets into it, mixing with the oil, it gives the color of coffee (This color can also be in cars that in the winter season, or just stood for a long time in an unheated garage, in this case, condensation appears inside the gearbox housing th and is converted into water, mixing with oil with all this), well, and the most common color is just black, oil can be exchanged for this color if you pour it into a dirty gearbox (It's just that the gearbox still needs to be washed from time to time from all the dirt, oh how to do this, read the article: "Flushing rear gear bridge on VAZ cars "), also over time the oil can change color to black when all the additives disappear and it will no longer be able to protect and lubricate the gearbox.

After the cork is wrapped, run over to fill in the oil, a special syringe will come in handy for you, which can be purchased at a car shop, and if you have a bottle with a very small neck, then you can use it, unscrew the filler plug in the gearbox for filling (Remember, we indicated the location of the drain and filler plug earlier in the pictures) and fill in the oil through the holes, it must be poured until it starts pouring out from you through the filler hole, because it starts to go back, finish filling the oil and screw the plug in its place and all the way.

Let's add a little to the article, on the gearbox there is still a breather on top (it is indicated by the arrow), it should move simply and without any third-party jamming, therefore rotate and press on it, by the way, if it does not work, then the oil through the oil seals can simply start to squeeze out when the gearbox will warm up (The higher the gearbox temperature, the more pressure is created inside it), read about this breather in the article: "Replacing the rear axle gearbox oil seal on cars"!

You can clearly see how to change the oil in the gearbox, you can see it in the video, which is a bit lower.

One of the main elements of the "classic" VAZ-2107 is the rear axle gearbox. This is a highly complex part of the system that takes the rotation of the engine's crankshaft and transfers it to the rear wheels. The rear axle itself stands on special rods, with the help of which it is connected to the car body.

The internal elements of the gearbox require constant and high-quality lubrication. For this, a special plug is provided on it, through which you can pump out the old and pump in new gear oil. Regular engine oil will not work. The explanation is simple. Gearbox parts operate under conditions of large temperature differences, as well as maximum loads. In such conditions, standard performance characteristics engine oil not enough.

Malfunction symptoms

The timing of replacing the transmission oil in the rear axle gearbox must be indicated in the instructions vehicle... But during operation, a number of symptoms may appear that will make a replacement much faster:

In the process of movement, an uncharacteristic whistle or noise of the gearbox appears. At the same time, it can disturb both when the load is applied to the gearbox, and without it;

There is a strong knock at the knot;

After a long parking, oil drips are visible under the car (in the area where the gearbox was located);

On examination, clear oily stains are visible.

If any of these symptoms appear, the oil level may need to be checked and subsequently replaced.

Why change your oil?

We have already mentioned that the oil in the rear gearbox works constantly, and the active rotation of the gears of the main pair leads to a significant increase in the temperature inside the unit. In some cases, this parameter can reach 130-150 degrees Celsius. High temperatures and contact with air lead to faster oxidation of hydrocarbons (they are the main source of most mineral oils).

What is the end result? The oxidation process is aggravated all the time, the lubricating composition becomes even more contaminated, and then clots and powerful deposits are formed. But that's not all. Over time, the viscosity of the oil deteriorates significantly, and its indicators approach the critical level. One "fine" day, gear oil may be a useless fluid in your car's gearbox.

Do not forget that there is no way to completely close the access of dust and dirt. Various debris inevitably gets inside and pollutes the system. Wear products, which are not removed anywhere and continue to be in the oil, also contribute. In such a situation, all units experience maximum loads - both bearings and gears, and oil seals.

What happens? After a few years, or even months of operation, transmission oil loses its properties. It is saturated with various debris, oxidizes and decomposes. There is only one way out in this situation - replacement.

When to change?

Each manufacturer is very vague about indicating the optimal frequency of oil change, clarifying that a lot depends on the operating conditions of the car. Ideal conditions include driving at medium speed on roads with normal coverage and no additional load (for example, a trailer).

In turn, private stops, short distance trips, frequent abuse of speed, operation in extreme conditions, transporting heavy loads, driving on dirty and dusty roads - these and a number of other factors inevitably reduce the overall life of the transmission oil and bring the day of its replacement closer. ...

Based on the mileage, it is recommended to change the oil in the gearbox every 20-30 thousand kilometers. In some cases, an unscheduled replacement may be necessary, for example, when buying a used car, after the car has been run-in, and after the completion of a major overhaul of the transmission. Believe me, such foresight, although it will lead to additional costs, will never be superfluous.

Oil change: step by step

So, you have decided on the need to change the oil in the VAZ-2107 gearbox. To do everything right, proceed in the following sequence:

1. Drive the car onto a pit or overpass as you need access from below. At the same time, keep in mind that it is better to change the oil on a heated car after a short trip (in this case, the oil will drain better).
2. Prepare everything you need for work - a container (for draining the old oil), new oil, hexagon to "12", spanner wrench to "17".
3. Unscrew the drain plug (it is located directly at the bottom of the crankcase) and place a container under the drain oil. Wait until all the oil has left the gear cavity. Be careful when unscrewing, because the temperature of the lubricating compound can reach 90-100 degrees Celsius.
4. Flush the gearbox. This is especially necessary if the old oil was black and was heavily contaminated with various debris. Flushing should be carried out with a composition having the highest possible viscosity.

1. Fill the gearbox with about a liter of flushing oil, jack up the rear wheel of the car and start the car. Turn on the first gear and let the car “drive” for one or two minutes. Then stop the engine and drain the flushing compound.
2. Now use a special syringe to pump new gear oil into the assembly. It's hard to make a mistake with the level. Oil must be poured along the lower edge of the neck, that is, to the maximum filling. Then the plug can be screwed on.
3. At the end of the work, be sure to clean the breather, which is necessary to reduce excess pressure in the reducer. That's all.

Conclusion

Many motorists underestimate the importance of timely oil change in the rear axle gearbox. And in vain, because the consequence of such negligence may be the failure of a serious and expensive unit. Therefore, be careful in this matter, and your car will certainly thank you for its reliability. Good luck.
