Try this, to measure belt side clearance, push the belt to one side of the the clutch shaft, and slide a feeler gauge between the side of the belt and the sheave of the clutch. I was reading an article about a Polaris and it says Polaris' should be between .010" and .020" for best performance and efficiency. Thanks again.
zr800 - i know this is kind of long, but here you go, straight out of the manual.
If premature drive belt wear is experienced or if the
drive belt turns over, parallelism/offset must be
checked. Also, parallelism/offset must be checked
whenever either the drive clutch or driven pulley is
serviced. To check the parallelism/offset, use the
Clutch Alignment Bar (p/n 0644-003) and the follow-ing
1. Open the belt guard and remove the drive belt.
2. Install the clutch alignment bar between the drive
clutch sheaves and against the outside edge of the
driven pulley stationary sheave.
3. Allow the alignment bar to rest on the drive clutch
.NOTE: The alignment bar must extend beyond
the front edge of the drive clutch.
4. With the bar against the outside edge of the driven
pulley stationary sheave at points A and B, the bar
should just clear the inside edge of the stationary
sheave of the drive clutch and rest on the
stationary shaft. If the bar does not clear the inside
edge or is more than 1.5 mm (0.060 in.) from the
inside edge, the offset must be corrected.
.NOTE: On the model with a wide ratio driven pul-ley
with the bar against the outside edge of the
driven pulley stationary sheave at points A and B,
the bar should have between 2.5-4 mm (0.100-0.160
in.) clearance to the inside edge of the sta-tionary
sheave of the drive clutch while resting on
the stationary shaft. If the clearance is not within
specifications, the offset must be corrected.
