ST1 498457000 ENGINE STAND ADAPTER RH
ST2 498457100 ENGINE STAND ADAPTER LH
ST3 499817000 ENGINE STAND
2) All parts should be thoroughly cleaned, paying special
attention to the engine oil passages, pistons and bearings.
3) Rotating parts and sliding parts such as piston, bearing
and gear should be coated with oil prior to assembly.
4) Be careful not to let oil, grease or coolant contact the
timing belt, clutch disc and flywheel.
5) All removed parts, if to be reused, should be reinstalled
in the original positions and directions.
6) Gaskets and lock washers must be replaced with new
ones. Liquid gasket should be used where specified to
prevent leakage.
7) Bolts, nuts and washers should be replaced with new
ones as required.
8) Even if necessary inspections have been made in
advance, proceed with assembly work while making
rechecks.

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.

B: INSPECTION
1. RELEASE BEARING
CAUTION:
Since this bearing is grease sealed and is of a nonlu-
brication type, do not wash with gasoline or any sol-
vent when servicing the clutch.
