CLUTCHING

Disassembly, Cont.
5. Measure the total thickness of the spacer washers
installed beneath spider and record
.
CAUTION:
NOTE: In order to maintain proper belt-to-sheave clear-
ance and clutch balance, the same washers (or equiva-
lent total thickness) must be reinstalled during assembly.
If sheaves are not marked, or if total thickness of existing
shim washers under spider is not recorded, clutch will be
out of balance when reassembled and must be replaced.
Be sure to follow indexing procedure on page 4.28 if belt-
to-sheave clearance is being adjusted.
6. Inspect both sheave surfaces for wear or damage.
Inspect movable sheave bushing. See page 4.43 for
inspection and repair procedure.
7. Using an 1/8s Allen wrench with a 3/8s combination
wrench, remove drive clutch fly weights. Note
direction of weight pin with nut on trailing side.
Inspect each weight. Surface should be smooth, with
no waves or galling. Place bolt inside weight to check
flyweight bushing and pin surface for wear.
NOTE: The weight bushing is not a service part and both
weight and pin must be replaced if worn.
8. Inspect all rollers, bushings and roller pins by pulling
a flat metal rod across the roller. Roller can also be
inspected by rolling with finger to feel for flat spots,
roughness, or loose bushing. Also inspect to see if
roller and bushing are separating. Bushing must fit
tightly in roller. Replace roller and pin if roller fails to
roll smoothly (flat spots) or if bushing is loose.
