Mc Leod RST, RXT User Manual

Installation Instructions for Kit #’s 6915, 6925 & 6975

The McLeod RST/RXT Modular Clutch Assembly is designed for extreme performance
applications. This clutch assembly is engineered to bolt directly onto the factory flywheel. Unlike most
clutch assemblies a typical clutch must be installed one component at a time. This system must not be
disassembled! Simply remove the factory clutch and install this entire assembly. If you ordered a
McLeod Flywheel with your clutch kit, it has been assembled to the flywheel for shipping purposes. Do
not disassemble the clutch kit to install the flywheel onto the crank. You only need to remove the base
plate to flywheel bolts! The factory flywheel contains small dowel pins used to align this clutch along
with the pilot tool. Do not remove the dowel pins from the flywheel. Install the alignment tool into the
splines on the clutch discs. Align the dowel pin holes on the base plate with the dowel pins and slide the
assembly into position on the flywheel. The alignment tool must be pushed forward all the way into the
pilot bearing. See Figure 1. Use the factory bolts to secure the RST/RXT Modular Clutch assembly to the
flywheel. Torque bolts to factory spec.

DO NOT DISASSEMBLE THIS UNIT!!

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

be corrected before installation of new clutch

corrected. If oil is present on clutch plate, cause of leak
unit.

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.

3) Remove ALL oil or grease from friction surfaces on flywheel and cover assembly. Surfaces

and dry. Also clean input shaft spline with a wire brush. Lubricate with dry graphite spray if needed.

4) To insure proper operation, friction surface of flywheel

be smooth and straight.

5) If throw-out bearing is worn, replace it, better now than later.

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.
