5. Inspect clutch and ensure that the scribed markings
made on the clutch plates have changed position.
Slippage has not occurred if any two marks on the
friction disk and plate are still aligned. A clutch that
has not slipped must be disassembled to separate
the friction disk plates. See “Clutch Disassembly,
Inspection & Assembly” below.
6. Tighten each of the 8 spring retainer nuts on the
clutch housing exactly 2 revolutions to restore clutch
to original setting pressure.
7. Allow clutch to cool to ambient temperature before
operating again. Clutch is now ready for use.
8. The clutch should be checked during the first hour of
cutting and periodically each week. An additional set
of scribe marks can be added to check for slippage.
See Figure 5-7 to adjust spring length.
Clutch Disassembly, Inspection & Assembly
Refer to Figure 5-6A and Figure 5-6B:
If clutch run-in procedure above indicated that one or more
friction disks did not slip, then the clutch must be
disassembled to separate the friction disks.
Disassembly
Disassembly of clutch is simply a matter of first removing
spring retainer nuts (#1), springs (#2), and bolts (#3)
from the assembly. Each friction disk (#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" (3.2mm) and should be
replaced if thickness falls below 3/64" (1.1mm). If
clutches 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.
Assembly
Reassemble each friction disk (#4) next to the metal
plate it was separated from. Install bolts (#3) through the
end plates and intermediate plates as shown. Place
springs (#2) over the bolts and secure with nuts (#1).
Refer to Figure 5-7:
Progressively tighten each spring retainer bolt until
correct spring height “A” is reached.
IMPORTANT: Not all clutches are assembled the
same with the same number of components. Be
sure to keep track of order and orientation of your
clutch components during disassembly.
