Clutch Disassembly
If the clutch run-in procedure, (See “Clutch Run-In” on
page 21), indicated that one or more of the friction disks did
not slip, the clutch must be disassembled to separate the
friction discs.

not slip, the clutch must be disassembled to separate the
friction discs.
Refer to Figure 5-2:
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 disk thickness is 1/8" and should be replaced if
the thickness falls below 3/32". If the clutch have been
slipped to the point of “smoking”, the friction disks may be
damaged and should be replaced. Heat build-up may
also affect the yoke joints.

Clutch Assembly
Refer to Figure 5-2:
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 5-3:
Progressively tighten each spring retainer bolt until
correct spring height (“A” dimension) is reached.

WARNING
Do not attempt to straighten a bent blade or weld on a blade.
Do not attempt to modify a blade such as hard surfacing, heat
treating, cold treating, or by any other method. Always
replace blades with a new Land Pride blade to assure safety.

Always inspect cutting blades before each use. Make
certain they are properly installed and are in good
working condition. Replace any blade that is damaged,
worn, bent, or excessively nicked. Never try to straighten
a bent blade! Small nicks can be ground out when
sharpening.
