The clutch cover is connected to the flywheel with six bolts. The flywheel has three pins that, when installed, fit into the corresponding holes in the casing, centering it. With three pairs of elastic steel plates with rivets, the casing is connected to the pressure plate. With the other three plates, the casing is connected to the thrust flange facing the clutch release bearing («clutch release»). This assembly is («basket» clutch) balanced on the stand, so it should be replaced entirely. Replacement is necessary if the surface of the pressure plate or «draft» springs.
The driven disk assembly with a spring vibration damper is installed between the flywheel and the clutch housing and can move along the splines of the gearbox input shaft. The disk is replaced when the beating in the lining area is more than 0.5 mm, if they crack, scuff or uneven wear, and also if the distance from the lining surface to the rivets is less than 0.2 mm.
The clutch release bearing is mounted on the clutch, which, when the clutch is engaged and disengaged, moves along the guide sleeve, acting on the thrust flange of the diaphragm spring. When the clutch is disengaged, there must be a gap between the bearing and the thrust flange, which is determined by the free play of the pusher of the clutch release fork (see Clutch Release Drive Adjustment). The bearing does not require maintenance or lubrication. It is replaced in case of increased noise when the clutch is engaged.
Clutch release fork - stamped steel, located in the clutch housing and oscillates on a ball joint (a recess is stamped under it on the fork). The fork is pressed against the ball joint by a leaf spring (riveted in the middle part of the fork). The ends of the fork abut against the clutch release bearing sleeve and are pressed against it by a curly spring. The hole for the clutch fork in the crankcase is closed with a rubber corrugated boot. The fork is constantly pressed against the pusher of the working cylinder by a withdrawal spring.
The clutch pedal is suspended on an axle in a bracket. To facilitate the effort when the clutch is engaged, a servo spring is fixed at its upper end. For guaranteed return of the pedal to its original position, a return spring is used (weaker). The pedal is pivotally connected to the pusher, which is included in the recess of the clutch master cylinder piston. The master cylinder is mounted in the engine compartment on two studs welded to the pedal bracket. The master cylinder is connected by a steel tube and a rubber hose to the slave cylinder fixed to the clutch housing with two bolts. When you press the pedal, the piston of the master cylinder compresses the fluid, the piston of the working cylinder extends and through the pusher acts on the clutch release fork. When the pedal is released, the fork under the action of the release spring presses on the pusher, returning the pistons to their original position.
The hydraulic clutch uses DOT-3 or DOT-4 brake fluid. Its stock is in a tank connected to the master cylinder by a rubber hose. Under the lid of the tank there is a rubber corrugated diaphragm that isolates the cavity of the tank from atmospheric moisture and dust. For pumping hydraulic (when replacing its parts or changing the fluid) there is a fitting on the working cylinder.
