Transmission repair, clutch disc replacement and clutch repair

Transmission of the car is a complex device, which includes clutch, gearbox, differential, cardan gear, drive shafts. Being in good order (and also provided only high-quality engine oil is used), all these components ensure a smooth and continuous operation of the car.

The reasons for which there is a need for repair of the transmission, there may be several, this is basically the breakdown of the mechanical gearbox, consisting in switching control on the fly, in the untimely replacement of filters and oil. Or in the box you can hear knocking, noise, there is a spontaneous switch-off.

Repair of the gearbox is a rather laborious and complicated process, since it is the main device of the mechanism that carries out the driver's will in speed, power and provides all the comfort of driving. Repair consists in removal of a transmission, its dismantling, carrying out of defectiveness, replacement of details and return assemblage. Therefore, replacing and repairing the gearbox, repairing the clutch and replacing the clutch discs requires a professional and demanding approach.

With proper maintenance, adjustment, and also with the correct driving style on the car, the clutch operates normally. Repair of the clutch or its replacement is necessary due to significant wear or breakage. One of the reasons for the repair of the clutch is a malfunction in the form of jerks, incomplete shutdown or stalling, clatter or noise. To eliminate these problems, you need a good repair of the clutch.

When slipping, the worn functional clutch disc linings or the disc itself are replaced. Also, pressure springs, which have lost elasticity, and heat-insulating washers are replaced.

Replacing the clutch disc is as follows:

To start, you need to disconnect the minus terminal from the body in order to avoid a short circuit.

Then you need to disconnect the hydraulic cylinder from the clutch mechanism, then make a jack lifting the car. Drain the gear oil. Remove the starter. Then it is necessary to unscrew and remove the gearbox from the engine.

Then unscrew the clutch from the engine flywheel. After removing the clutch cover and the driven disc, check the condition of all parts. The rivet heads should be deepened by 1.1 mm, if this figure is less, then the disk must be replaced.

When installing the slave drive in the casing, the part that protrudes relatively out of the hub must be directed towards the spring.

Install the discs on the flywheel, while firmly tightening the fastening bolts.

If the clutch repair is carried out for the reason Incomplete inclusion, then the clutch disc is straightened. After that, the binding of the hub is eliminated. Further, the friction linings, which are broken or weakened by rivets, are replaced.

If the clutch is engaged in jerks, the clutch disc is replaced, since the spring plates have lost their elasticity or the springs of the torsional vibration damper have failed. After that, the working surface of the flywheel and the clutch disc is cleaned, or the oily surface of the clutch disc is cleaned. Then it is necessary to replace the bearing of the gearbox.

Carrying out the repair of the clutch in the event of noise, knocking or rattling, replacement of the clutch disc broken by a damper is made (damper - torsion damper). Further, the pressure bearing and splined joint parts are replaced , as well as the bearing of the front end of the drive shaft of the gearbox. After that, the clutch cover is replaced with a weak diaphragm spring.
