2. Measure the wear of the diaphragm spring fingers using a vernier caliper.
Maximum wear 0.6 mm (0.024 in)
If it exceeds the maximum specification, replace the clutch cover.
3. Measure the pressure plate flatness using a straight edge and a feeler gauge.
Note:
^ Measure the pressure plate flatness across the center.
Maximum flatness 0.5 mm (0.020 in)
^ If it exceeds the maximum specification, replace the clutch cover.
4. Attach a dial gauge to the rear housing, rotate the flywheel, then inspect for height difference between the diaphragm spring fingers.
Maximum height difference 1.0 mm (0.039 in)
If it exceeds the maximum specification, replace the clutch cover.
