NOTE: Install a new clutch disc if any of these conditions are present. Always install a new clutch pressure plate when installing a new clutch.

Inspect the clutch for the following:
- Oil or grease contamination
- Worn or loose facings
- Distortion
- Broken springs
- Burrs or uneven wear on the splines
- Wear or damage on the clutch disc surface
