Spider Indexing - Polaris INDY TRAIL RMK Service Manual

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 starting on
page 5.13. 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.
For example: If belt to sheave clearance is .020²
S
too large, removing one .020² shim will position
the movable sheave closer to the fixed sheave
reducing belt to sheave clearance by .020².
NOTE:The following washers are available for fine tuning:
Washers:
PN 5210754 .050²
PN 5210753 .032²
PN 5210752 .020²
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.
Vary the amount and thickness of spacer washers
S
(Washer thickness may vary slightly).
Re-index marked spider leg to another tower.
S
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:
.020² or .032² washer removed - re-index
S
spider clockwise 1/3 turn
.050² or .064² washer removed - re-index
S
spider clockwise 1/3 turn
Two .050² or .064² washers removed -
S
re-index clockwise 2/3 turn
NOTE: Alignment marks should be within 1² (25 mm) af-
ter final assembly and torquing.
