| 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. |
