Drive Belt Installation - Polaris Trail Boss 330 2003 Service Manual

8. Replace belt if worn past the service limit. Belts
with thin spots, burn marks, etc., should be
replaced to eliminate noise, vibration, or erratic
PVT operation. See Troubleshooting Chart at the
end of this chapter for possible causes. NOTE: If
a new belt is installed, check belt deflection.

DRIVE BELT INSTALLATION

1. Loop belt over drive and over top of 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.
NOTE: Be sure to position belt so part number is
easily read.

Disassembly, Pages 6.5.
4. Remove PVT inner cover.
5. Loosen all engine mounts. Move front of engine
to the right or left slightly until alignment is correct.
6. Tighten engine mounts and verify alignment is
correct.
Center line
Measure offset above and below
centerline
7. Measure belt deflection and measure offset both
above and below sheave centerlines. Adjust if
necessary.
NOTE: On some models, minor adjustments can be
made by adding shims between the frame and front
lower left engine mount to increase the distance at
point "A". If a shim is present, it can be removed to
decrease the distance at point "A".
