flywheel side or pressure plate side facing the respective
part. Do not allow the hubs to be within less than 5/32 inch
(3.967 mm) of the pilot bearing, or each other.
6. Bolt the clutch assembly to the engine flywheel. Tighten
each capscrew gradually until the ring is drawn up tight.
Make certain that the clutch ring IS seated properly on the
flywheel pilot rim.
NOTE
If the release levers are not in plane, it is possible that
the ring is not seated properly on the flywheel.
7. Remove the three capscrews that were installed through
the clutch ring, into the pressure plate.

5. Pull the adjusting nuts up through the holes in the
clutch ring, and install the locknuts.
6. Install three 3/8" - 16 x 2-1/4" capscrews through the
clutch ring into the tapped holes in the pressure plate to
hold it under compression while reassembling the clutch to
the engine flywheel. Remove the clutch assembly from the
arbor press.
INSTALLATION. To install the clutch assembly on the
engine flywheel. proceed as follows:
1. Check the depth of the recess in the engine flywheel.
The depth of the recess must be within 0.005 inch (.127
mm) of 1.062 inches (26.974 mm).
2. The friction face of the flywheel must be free from heat
cracks, score marks, or taper. The presence of any of these
conditions will adversely affect clutch life.
3. Install the release bearing and carrier, and the pilot
bearing. The pilot bearing should be a hand press fit in the
flywheel recess and on the transmission input shaft. The
release yoke should contact the release bearing carrier
evenly to prevent a bind on the front bearing cap extension.
4. Place the intermediate plate in the driving slots of the
