Shift Weight Inspection - Polaris RANGER 500 2018 Service Manual

PVT SYSTEM
Drive Clutch Spring Inspection
CAUTION
Never shim a drive clutch spring to increase its
compression rate. This may result in complete stacking
of the coils and subsequent clutch cover failure.
The drive clutch spring is one of the most critical
components of the PVT system. It is also one of the
easiest to service. Due to the severe relaxation the
spring is subject to during operation, it should always
be inspected for tolerance limits during any clutch
operation diagnosis or repair.
With the spring resting on a flat surface, measure its
free length from the outer coil surfaces. Also check to
see that spring coils are parallel to one another.
Distortion of the spring indicates stress fatigue,
requiring replacement.

SHIFT WEIGHT INSPECTION

1. Remove shift weight bolts and weights. Inspect the
contact surface of the weight
be smooth and free of dents or gall marks. Inspect
the weight pivot bore and bolts
If weights or bolts are worn or broken, replace in sets
of three with new bolts and nuts.
WARNING
The clutch assembly is a precisely balanced unit. Never
replace parts with used parts from another clutch
assembly!
A damaged shift weight is usually caused by a
damaged or stuck roller in the spider assembly. See
"Roller, Pin and Thrust Washer Inspection".
