What is included in the clutch VAZ 2107 and the replacement procedure

In this article we will consider the coupling of the VAZ 2107, its main components and the replacement procedure on the car. It is also worth noting that this node is structurally similar to that used on "pennies", "sixes", in other words, on the entire classic series of rear-wheel drive cars VAZ. And the procedure of replacement, repair, is similar. The difference can be observed only in the removal of the gear lever when dismantling the gearbox. Namely - in removing the elements of the "beard".

The main clutch units

The two main power units of the car are the engine and the gearbox. Between them there are several elements: a flywheel, a disk, a plug, a squeeze bearing, a basket. The clutch of the VAZ 2107 consists precisely of these parts. They allow during the movement to disconnect the engine's input shaft from the gearbox. This is done with a hydraulic drive located from the outside.

And now a little about how everything works. Let's say you need to switch the speed. To do this, you press the clutch pedal. At the same time, the fork with the release bearing acts on the petals of the basket. As a result, a small gap is created between the surface of the disc and the basket. Consequently, the shafts of the box and the motor disconnect, begin to rotate independently of each other. It is at this point that you can carry out gear changes, the box is maximally unloaded.

Clutch drive

You can even draw an analogy with the braking system. Contains clutch VAZ 2107 working cylinder and main. The first is mounted on the clutch housing and is attached to it using two bolts. The second one is directly opposite the drive pedal. From it go two hoses - to the expansion tank and to the working cylinder. With the help of the expansion tank, a constant level of liquid is maintained. Again, an analogy with the braking system.

Even by design, both cylinders are very similar to GTZ. Functions, however, are slightly different. On more modern cars, instead of a cylinder system, a cable is used. It is caused by two reasons - cheaper and simpler. If we compare the cost of a cable and a cylinder, then it is more than two times lower. Therefore, it turns out to be quite expensive in servicing the VAZ 2107. The price of the cylinder is at least 500 rubles. True, its reliability is quite high.

How do I remove the gearbox?

If you feel that the clutch is starting to work incorrectly, there is extraneous noise, it leads, when the accelerator pedal is sharply squeezed, there is an increase in speed, but the speed does not change, this indicates that a replacement is necessary. Clutch VAZ 2107, like any other car, changes only after the complete removal of the box. For this, it is necessary to conduct a number of activities. Repair is best done on a car mounted on a pit or lift.

First of all, work is done from above - the terminal is removed from the battery, the shift lever is disassembled, the mass wires, the starter, and the pants are disconnected. It is worth noting that it is necessary to purchase a new gasket and nuts under the pants. Then work is carried out from below - the cardan shaft is disconnected, the cushion fixing nuts are loosened to the body, the clutch slave cylinder is removed . Disconnect the speedometer drive and the reverse signal connector. After this, it will be necessary to unscrew the four bolts that securing the transmission to the engine block. Note, it is necessary to install a support under the box, so that it does not fall during removal.

Procedure for replacing the clutch

Changing the clutch of VAZ 2107, the price of a set of about 2000 rubles, not for long. Most of the time, the removal and installation of the gearbox takes place. Try not to damage the clutch basket while removing the gearbox. After all, it changes much less often than a disk and a bearing. But in any case, you need to put new bolts. The fact is that when working on the thread on the old slightly deformed, it is possible that they can not provide a reliable connection.

As with the removal of the basket, and during its installation, it is necessary to screw / unscrew the bolts diagonally. This will ensure a uniform tightening. Do not forget to change the release bearing and carefully inspect the condition of the plug. If it has defects, replace it. Also, do not deprive yourself of the attention and the crown of the flywheel. If his teeth are worn out, then it will be necessary to either turn it over, or put a new one. The installation of the basket and the disk must be carried out only after alignment by means of a tube (or a segment of the input shaft of the gearbox).

Adjustment and bleeding system

After changing the clutch and assembly, you need to adjust. Without this procedure will not work properly grip VAZ 2107. The working cylinder needs to be adjusted a little. On the rod there is an adjusting nut, which must be screwed or unscrewed to achieve maximum efficiency. If pumping is necessary, then fill the expansion tank with brake fluid. The assistant squeezes the clutch pedal, and at that moment you turn the choke and release the air from the system. Everything is done in the same way as pumping the brakes, only much faster.

Conclusion

That's all you can tell about how the replacement is done. Coupling VAZ 2107 after this procedure will work stably and without failures. Do not forget to put all the plugs in their places after the assembly. In particular, the connector for connecting the reverse signal. If necessary, replace the speedometer drive cable.
