GENE1AI DESCRIPTION
Several clutches are being used, depending on the
engine option. The clutches differ in diaphragm
spring design, damper spring calibration and driven
disc diameter. Clutch usages are shown in Fig. 1.
PERIODIC SERVICE
LUBRICATION
Every 6,000 miles, lubricate all pivot points with
engine oil. Use light grease at push rod to clutch
fork pin joint and chassis grease at high pressure
lubrication fitting. The ball type release bearing
is lubricated and sealed for life and requires no
lubrication.
CLUTCH PEDAL ADJUSTMENT (Figs. 7-3, 7-4 and 7-5)
Wear on the clutch parts necessitates occasional
lash adjustment. No other adjustment is made. Lash
adjustment should be made as follows:
1. Remove the return spring.
2. With clutch pedal against stop: Loosen jam nut
sufficiently to allow the adjusting rod to be turned
out of swivel and rearward against the clutch fork
until the release bearing contacts pressure plate
fingers lightly.
3. Rotate adjusting rod into swivel 3 1/2 turns and
tighten jam nut 10 lb. ft. torque.
4. Reinstall spring. Approximately 1" of lash
should be at the pedal.
