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.

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.
