Clutch Disassembly
If the clutch run-in procedure, (See “Clutch Run-In” on
page 24), indicated that one or more of the friction disks did
not slip, the clutch must be disassembled to separate the
friction discs.
Refer to Figure 4-3:
See IMPORTANT NOTE above before disassembling
clutch. After measuring and recording each spring length,
remove spring retainer nuts (#1), springs (#2), and bolts
(#3). Each friction disc (#4) must then be separated from
the metal surface adjacent to it.
Inspection
Inspect all parts for excessive wear and condition. Clean
all parts that do not require replacement.The original
friction disc thickness is 1/8" (3.2 mm) and should be
replaced if thickness falls below 3/64" (1.1 mm). If
clutches have been slipped to the point of “smoking”, the
friction discs may be damaged and should be replaced.
Heat build-up may also affect the yoke joints.
Clutch Assembly
Refer to Figure 4-3:
Reassemble each friction disk (#4) next to the metal plate
it was separated from. Make certain all bushing are
replaced in the same location as when removed. Install
bolts (#3) through end plates and intermediate plates as
shown. Place springs (#2) over the bolts and secure with
nuts (#1).
Refer to Figure 4-4:
Progressively tighten each spring retainer bolt until
correct spring height (“A” dimension) is reached.

track of order and orientation of
your clutch components during disassembly
IMPORTANT: Refer to Figure 4-4. Be Sure to
measure and record length (“A”) of each spring
before disassembling the clutch.
