1. Clutch System

1. General
A: PRECAUTION
When servicing clutch system, pay attention to the follow-
ing items.
1. MECHANICAL APPLICATION TYPE
1) Check the routing of clutch cable for smoothness.
2) Excessive tightness or looseness of clutch cable have
a bad influence upon the cable durability.
3) Apply grease sufficiently to the connecting portion of
clutch pedal.
4) Apply grease sufficiently to the release lever portion.
5) Position clutch cable through the center of toe board
hole and route it smoothly. Adjustment is done by moving
the outer cable.
6) Make sure not to let the clutch chatter when starting
forward or rearward. If clutch chattering occurs, readjust so
that the bend of clutch outer cable becomes flatter.
