Pvt Break-In (Drive Belt / Clutches); Clutch Alignment - Polaris MS4000 Service And Owner's Manual

CLUTCHING
Belt Inspection
1. 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.
2. Inspect belt for loose cords, missing cogs, cracks,
abrasions, thin spots, or excessive wear. Compare belt
measurements with a new drive belt. Replace if necessary.
3. Belts with thin spots, burn marks, etc., should be replaced
to eliminate noise, vibration, or erratic PVT operation. See
the Troubleshooting Chart at the end of this chapter for
possible causes.
Belt Installation
1. Loop belt over the drive clutch and over top of the driven
sheave.
2. While pushing down on top of belt, turn the back or
moveable driven sheave clockwise.
3. The belt then should be able to be pushed down into and
between the sheaves.
Be sure to position belt so part number is easily read.

PVT Break-In (Drive Belt / Clutches)

A proper break-in of the clutches and drive belt will ensure a
longer life and better performance. Break in the clutches and
drive belt by operating at slower speeds during the 10 hour
break-in period as recommended (see Chapter 3 "Engine
Break-In Period" for break-in example). Pull only light loads.
Avoid aggressive acceleration and high speed operation during
the break-in period.

CLUTCH ALIGNMENT

Clutch Alignment Tool Use
Clutch alignment is controlled by the number of washers that are
placed behind the driven clutch on the transmission input shaft.
Adding washers behind the driven clutch will move the drive
belt toward the moveable sheave of the drive clutch. Removing
washers from behind the driven clutch will move the drive belt
toward the stationary sheave of the drive clutch.
1. Remove the seat.
2. Remove the LH storage box to gain access to the outer PVT
cover (see Chapter 5 for removal).
3. Loosen the hose clamp and remove the PVT air outlet duct
hose from the outer PVT cover.
4. Remove all outer PVT cover screws and remove the cover.
5. Mark the drive belt direction of rotation and remove drive
belt (see "Drive Belt Removal").
6. Install the Clutch Alignment Tool.
