Clutch Alignment /Offset - Polaris Magnum 2x4 Service Manual

5. Measure belt length with a tape measure around the outer
circumference of the belt. Belts which measure longer
than nominal length may require driven shimming or
engine adjustment for a longer center distance to obtain
proper belt deflection. Belts which measure shorter than
nominal length may require driven shimming or a shorter
center distance. Remember, proper belt deflection is the
desired goal - not
a
specific center distance.
6. 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.
Clutch Alignment
1. Remove belt and install offset/alignment tool as shown.
2. With tool touching rear of driven clutch inner sheave, the
distance at point "A" should be 1/8".
It the distance is greater than 1 /8" or less than 1 /16", clutch
alignment must be adjusted as follows:
3. Remove drive and driven clutch. See PVT Disassembly,
page 6.9.
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.
7. Measure belt deflection and offset and 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 pres-
ent, it can be removed to decrease the distance at point "A".

Clutch Offset
Important:
Inspect clutch alignment and center distance be-
fore adjusting offset.
1. Install offset alignment tool as shown.
Offset is correct when rear of tool contacts rear of inner
sheave with driven clutch pushed completely inward on shaft
and bolt torqued. Adjust offset by adding or removing spacer
washers between back of driven clutch and spacer as shown.
