NOTE: Do not apply lubricant to the input shaft splines. The dust will contaminate the lubricant and cause slow
clutch response time.
NOTICE: The flywheel and/or pressure plate can be damaged if the pressure plate assembly is not compressed
incrementally.
NOTE: If appropriate, replace the pilot bearing at this time.
1. Insert the clutch alignment tool (1), with the disk installed, into the pilot bearing.
2. Install guide pins (1) in the flywheel.

3. Position the pressure plate, with the adjustment release (2), in the top-most bolt group (4), and hang it on the guide pins
(1).

5. Replace the guide pins with clutch bolts, and install finger-tight.
NOTICE: While tightening the pressure plate bolts, if the force required changes significantly before the
diaphragm spring is fully compressed, the pressure plate may not have piloted into the counter-bore of the
flywheel correctly. Back all the bolts off and start over or the flywheel could be damaged.
NOTE: During the first steps of the tightening process, confirm the clutch alignment tool is centered and movable
in the disk/pilot bearing. Otherwise it will be difficult to remove the tool and install the input shaft.
6. Go to the bottom-most bolt group and, while lifting the pressure plate into alignment with the flywheel bore, tighten
one of the three bolts (3), two turns.
7. Move clockwise around the flywheel in the sequence shown, turning one bolt in each group two turns.
8. Change to a criss-cross pattern and continue tightening the same four bolts. Tighten one turn each, until the pressure
plate is seated against the flywheel.
