Pressure Plate: Testing and Inspection

INSPECTION
1. Inspect the pressure plate surface for wear, cracks, and burning.
2. Inspect the fingers of the diaphragm spring for wear at the release bearing contact area.
3. Inspect for warpage using a straight edge and feeler gauge. Measure across the pressure plate at three points.
- Standard (New): 0.03 mm (0.001 inch) max.
- Service Limit: 0.15 mm (0.006 inch).
- If the warpage exceeds the service limit, replace the pressure plate.
