5. Measure diaphragm finger height above bolted surface of pressure plate.

Diaphragm finger height: new clutch plate = 29.1 - 32.0 mm service limit = 36.5 mm

Renew pressure plate if clearances are outside service limit.

6. Using a socket and extension bar on crankshaft pulley bolt, rotate crankshaft until flywheel locking pin 18G 1523 can be inserted through hole in gearbox mounting plate and into hole in flywheel.

7. Progressively loosen and then remove 6 bolts securing pressure plate to flywheel.

9. Inspect clutch drive plate for signs of wear or oil contamination. Check for broken or loose springs and signs of cracking at spring windows. Renew drive plate if necessary.
10. Measure depth of rivets on drive plate, renew drive plate if less than service limit.

Drive plate rivet depth: new clutch plate = 1.0 mm minimum service limit = 0.2 mm

11. Measure drive plate run-out by fitting drive plate to a gearbox mainshaft and use a dial gauge as drive plate is rotated. Renew drive plate if outside service limit.

Drive plate run-out: New clutch plate = 0.8 mm Service limit = 1.0 mm
