Spider Indexing - Polaris IQ 2007 Service Manual

Spider Indexing

NOTE: Spider indexing effects belt to sheave
clearance and clutch balance. Please read all
procedures before proceeding.
1. Remove and disassemble clutch
2. Add or remove spider washers as required to achieve
desired belt to sheave clearance. Make sure that the stepped
washer (A) is on the bottom of the spacer stack (B). 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".
3. Place the correct number of spacer washers (B) beneath the
spider. The following washers are available for fine tuning:
• 5210752 - .020" (.51mm)
• 5242981 - .025" (.63mm)
• 5210753 - .032" (.81mm)
• 5210754 - .050" (1.27mm)
• Clutch Spacer - .130" (3.3mm)
4. Install spider washer(s) and spider aligning the "X" with the
moveable sheave's "X". Notice as the spider seat location
is changed, the sheave marks made before disassembly no
longer align (C). There are two ways to bring the sheave
marks into alignment.
(A)
(B)
Vary the amount and thickness of spacer washers (washer
thickness may vary slightly). 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 (D). For EXAMPLE: 0.020" or 0.032" (0.5
- 0.8mm) washer removed - re-index spider clockwise 1/3 turn.
NOTE: Alignment marks on the sheaves should be
with in 1" (25.4mm) after final assembly and
torquing.
