CLUTCHING

Spider Indexing

NOTE: Spider indexing affects clutch balance and belt
to sheave clearance. Read procedures carefully before
proceeding.
1. Before disassembling drive clutch, mark spider,
cover, moveable sheave, and stationary sheave in
line with a permanent marker as shown.
2. Disassemble drive clutch as described on page
4.20-4.21. Take care to note the amount and
thickness of the shim washers under the spider.
3. Add or remove spider washers as required to
achieve desired belt to sheave clearance.
S
For example: If belt to sheave clearance is .020
too large, removing one .020 shim will position
the movable sheave closer to the fixed sheave
reducing belt to sheave clearance by .020 .
NOTE: The following washers are available for fine tuning:
Washers:

PN 5210753
PN 5210752
PN 5132542
tion to one of the above shims for pre-
cise shimming
4. Install spider washer(s) and spider aligning Xs.
Notice as the spider seat location is changed, the
sheave marks made before disassembly no longer
align. There are two ways to bring the sheave marks
into alignment.
S Vary the amount and thickness of spacer washers
(Washer thickness may vary slightly).
S Re-index marked spider leg to another tower.
This can be done because spider has little effect
on overall clutch balance.
Re-indexing the spider 1/3 turn clockwise, or 1 leg, will
allow the realignment of the moveable and stationary
sheaves as previously marked. For example:
S
.020 or .032 washer removed - re-index
spider clockwise 1/3 turn
S .050 or .064 washer removed - re-index
spider clockwise 1/3 turn
S
Two .050 or .064 washers removed -
re-index clockwise 2/3 turn
NOTE: Alignment marks should be within 1 (25 mm) af-
ter final assembly and torquing.
