VAZ 2106: rear axle, reducer. Adjustment, repair, replacement

If you find that the rear axle (reducer) is overheating or emits characteristic noises at the VAZ 2106, in this case only the replacement will save the situation. To change this part is really easy - with this can even handle a novice motorist. And today we will consider how the gearbox is replaced (VAZ 2106 "Six").

Do I have to change it?

Of course, there are other ways to solve the problem. Instead of buying a new part, you can repair the gearbox VAZ 2106. However, doing this in garage conditions is highly discouraged, since you can not just set the gap in the meshing of the gears correctly. That's why the most reliable solution is to buy a new item. Fortunately, its cost is not so great (about 4 thousand rubles), so from the point of view of finance your costs will be minimal.

Cooking tools

In order to replace the rear gearbox VAZ 2106 quickly and correctly, we need to prepare the following set of tools:

• Set of spanners and spanners.
• "Plus" and "minus" screwdriver.
• A solvent like the "White Spirit" or a bottle of gasoline.

Getting Started

To begin dismantling the bridge, you must first drive the car to a pit or a flyover. Then it is necessary to drain the oil and disconnect the propeller shaft with the flange of the shank of the gear.

After this, the semi-axles are removed from the machine and 8 fixing bolts are twisted using the face spike, which connect the reducer to the beam. Then you can safely remove from the car VAZ 2106 rear axle (reducer). At this stage, you can go in two ways - to install a new element or try digging into the old one. In the first moment, the elements are assembled in the reverse order, but here's how to proceed in the second case, in the next sections.

About sealing elements and their replacement

Note that on the first models of the "Six" the connection of the bridge and flanges was done with sealing by a special gasket. Several years later, instead of it, a sealing oil-resistant agent was used on the conveyor. Therefore, in any case, it is necessary to update this seal during the reverse installation.

What do you need to do next? The next step is to thoroughly clean the surface of the reducer connectors from the sealing substance, and then, with a cloth previously moistened in gasoline, degrease the surface. If you use White Spirit, take care of additional respiratory protection. Also the threads of fixing bolts and the holes for them located in the jar are to be degreased.

Further, all these surfaces are treated with a new oil-resistant sealant. The thread of the fixing bolts is lubricated with a special fixing compound.

Then the reducer of the bridge is mounted in a beam and tightened by a bolt evenly (criss-cross). Installation of the remaining elements is carried out in the reverse order. Finally, it is necessary to fill a new oil in the rear axle.

How to fill in the oil?

Before disclosing the features of the replacement, it should be noted that this instruction can be used not only for cars of model 2106. A similar algorithm for oil change can be observed in VAZ cars of model 2101, 2102, 2104, 2105, and also model 2107.

So, what do we need to do to replace the oil? First it is necessary to unscrew the drain plug with a hexagonal wrench. Next, put some capacity and unscrew the filler element. After the oil is well glass, turn the cork back and use a special oil pump (or a large syringe) to pump in the gear oil here . Pour to the level of the bottom edge of the hole. Further we twist a stopper, and on it it is possible safely to start operation of the car.

Sometimes the substance in the gearbox can be heavily soiled. In this case, before pouring a new liquid, thoroughly wash the crankcase of the gearbox or gearbox with a mixture of diesel oil and oil (not necessarily transmission oil). In a proportion, about 300 milliliters of solar oil comes out on a liter of oil.

How to adjust the gearbox VAZ 2106 own?

This operation is performed after each disassembly and repair of this part. But not always. Determine whether adjustment is necessary to the gearbox, because of the presence of axial play of the driving gears. This is done with the help of an indicator with a price of division of 0.01 millimeter. Check for backlash is performed with the propeller shaft disconnected by moving the flange in the axial direction.

The indicator foot is mounted on the end of the flange. By adjusting the tension, the axial clearance in the bearings is removed. To make such adjustment it is possible by selection on a thickness of adjusting rings. How does the rear axle (gearbox) change further on the VAZ 2106?

Before final assembly of the gear unit, the gears must also be engaged. In order to do this, you need to paint the teeth of the device with some bright paint. Too liquid for this work is not recommended, as its properties do not fit (it will simply spread over the teeth). But thick should not be preferred - this will not be squeezed out of the gaps between the elements (that is, the result of it - no). After applying the paint, it is necessary to rotate the drive gear in different directions. In this case, it is necessary to stop the revolutions when it hits the slave. Do this until the teeth have a clear contact spot. On it we determine the correctness of the adjustment.

If in the course of the work you have a need to move the driven gear, you can do this by changing the thickness of the set of shims. The latter are installed between the end of the gear and the inner ring of the rear bearing.

So, we found out how to replace the rear axle (gearbox) on the VAZ 2106 car and how to properly adjust it. By the way, on services for a similar job take from 2 to 3 thousand rubles - almost the full cost of the most replaced part.
