NOTE: At least one shim must remain between the
inner and outer sheave of the driven clutch. If proper
beltdeflectioncannot beobtained, measuredrive belt
width, length, and center distance of drive and driven
clutch, outlined in this section; all have an effect on
belt deflection.

REMOV
AL/INSPECTION
1. Remove outer PVT cover as described in PVT
Disassembly.
2. Mark drive belt direction of rotation so that it can
be installed in the same direction. NOTE:
Normally positioned so part numbers are easily
read.
3. To remove drive belt: apply brake, pull upward

Belt Width:
New 1.174 - 1.188″ (2.98-3.02 cm)
Wear Limit 1.125″ (2.86 cm)
4. Measure belt width and replace if worn severely.
Generally, belt should be replacedif clutches can
no longer be adjusted to provide proper belt
deflection.

abrasions, thin spots, or excessive wear.
Replace if necessary.
6. Inspect belt for hour glassing (extreme circular
wear in at least one spot and on both sides of the
belt). Hour glassing occurs when the drive train
does not move and the drive clutch engages the
belt.
