Clutch control (VAZ-21213)

The clutch is checked on a base that imitates the engine flywheel and has a metal intermediate ring 4 (Fig. 3-5) 8.2 mm thick, replacing the driven disk. Having secured the clutch housing, perform four disengagement strokes equal to 8-9 mm. The disengagement stroke of 8 mm should correspond to a movement of the pressure plate by 1.6-1.7 mm (the smallest permissible is 1.4 mm).



The distance from the base to the working surface of the friction ring of the thrust flange should be 40-43 mm. During operation, due to wear of the friction surfaces of the clutch discs, this size increases. If it reaches 48 mm or the movement of the pressure plate is less than 1.4 mm, replace the clutch housing assembly with the pressure plate.

Replace the friction linings of the driven disk if cracks appear, the distance between the rivet and the working surface decreases to 0.2 mm, and if there is one-sided scoring. When repairing the driven disk and replacing the friction linings, use tool 67.7822.9529 (Fig. 3-6).



The flared rivets must not have any breaks. The runout of the working surface of the friction linings must not exceed 0.5 mm. If it is more, straighten the disk (Fig. 3-7) or replace it with a new one. If cracks appear on the driven disk or damper springs, replace the driven disk as an assembly.
