Checking Pressure Plate Assembly and Flywheel
1. Wash the disassembling parts except clutch disc with a suitable
cleaning solvent to remove dirt and grease before making
inspection and adjustment.
2. Inspect the friction surface of pressure plate and flywheel for
scoring or roughness.
- Slight roughness may be smoothed by using fine emery cloth.
- If these parts have deep scores or grooves on their surface,
they should be replaced.
3. Inspect the surface of diaphragm spring for wear.
If excessive wear is found, replace the clutch cover assembly.
