Important Clutch Installation Hints
The following check list is a reminder of the necessary inspection points
and precautions required to insure a trouble-free clutch installation.
Installation / Do’s
1) Determine cause of original clutch failure. Cause of first clutch failure (if not wear) MUST be found and
corrected. If oil is present on clutch plate, cause of leak MUST
2) Check splines on transmission input shaft for signs of abnormal wear or twisting. Slide new disc on spline
by hand gently to check fit. Disc should move FREELY on splines.
be corrected before installation of new clutch
unit.
3) Remove ALL oil or grease from friction surfaces on flywheel and cover assembly. Surfaces MUST
4) To insure proper operation, friction surface of flywheel
be clean
and dry. Also clean input shaft spline with a wire brush. Lubricate with dry graphite spray if needed.
MUST
5) If throw-out bearing is worn, replace it, better now than later.
be resurfaced. Check dowel pins, they must
be smooth and straight.
6) Closely inspect pilot bearing or bushing for excessive wear to avoid transmission shaft misalignment.
Replace it if any doubts.
7) Use clutch alignment tool to insure disc and cover are properly aligned with pilot bearing.
8) If using an aftermarket scatter shield/bell housing, checking center hole run-out is highly recommended.
9) Be sure all special type bolts, if any, are replaced in their proper locations.
10) Torque all clutch cover bolts evenly, to factory recommended spec, using a progressive “criss-cross”
tightening pattern.
11) Before completing installation, inspect all clutch linkage parts (fork, clevis, pins, etc.) for signs of wear and
replace ALL worn pieces. Grease all pivot points in linkage system.
12) Adjust clutch pedal “free play” to correct specifications. Throw-out bearing should not be tight against
clutch fingers. 1/8” – ¼” is recommended, except cable linkage.
