7.1.7. Leading knot of coupling


1. Remove the transmission.
2. Note the provision of the leading knot of coupling in relation to a flywheel, using a marker or paint.
. 3. Gradually in the diagonal sequence weaken bolts of the leading knot of coupling, turning each bolt on a half of a turn until it is terminated a spring, and bolts can be unscrewed manually.
4. Remove the leading knot of coupling and a clutch plate.


1. Check overlays of a clutch plate for wear, mechanical damages or pollution by oil.
2. With these defects the clutch plate needs to be replaced.
3. If frictional slips in good shape are also not worn-out to grooves, springs of a damper are reliably fixed and rivet connections are not loosened, then the clutch plate can be installed in the car.
4. If the clutch plate is polluted by oil, check the left oil sealing ring of a bent shaft or a main shaft of the transmission. If necessary replace sealing rings before installation of a new clutch plate.
5. Check knot of a drive plate for wear of a press disk, mechanical damages, reliability of rivet connection, damage of a diaphragm spring of coupling. If the spring of a diaphragm is worn-out or damaged, or there are suspicions that elasticity of a spring changed, then it is necessary to replace knot of a drive plate.
6. Check the working surfaces of a press disk and a flywheel interfaced to overlays of a clutch plate. They have to be pure, flat and not have scratches and development.
7. Check press the bearing which has to rotate easily, evenly and silently. The working surface of the bearing influencing a press spring has to be smooth, without cracks, local corrosion or development. If there are these defects, the working cylinder of coupling needs to be replaced.


Installation is made in the sequence, the return to removal. At the same time a mandrel center a clutch plate in order that the main shaft of the transmission passed through grooves in the center of a clutch plate.
