8.5.1. Check of thickness of a clutch plate in the mounted state

Coupling is self-regulating system and does not demand maintenance therefore it is impossible to determine wear of a clutch plate by a coupling pedal side play. To check clutch plate thickness in the mounted state, the special control template which can be made independently is required.

1. Make a control template of sheet metal 0,8 mm thick in scale 1:1.
2. Raise the car.
3. Insert a template (4) on the distributing device of coupling against the stop into a groove of a plastic insert.
4. If the cut-out marks of a template (shooter) drown behind a flange of the distributive cylinder of coupling, then the clutch plate still has sufficient thickness.
5. If the cut-out marks remain visible though the template is inserted against the stop, then in this case the clutch plate already reached the limit of wear and has to be replaced.
6. Lower the car.
