Bearing Inspection; Clutch Inspection - Polaris 2009 Sportsman XP 850 Service Manual

2. Remove shift weight bolts and weights. Inspect the contact
surface of the weight. The surface should be smooth and
free of dents or gall marks. Inspect the weight pivot bore
and pivot bolts for wear or galling. If weights or bolts are
worn or broken, replace in sets of three with new bolts.
NOTE: A damaged shift weight is usually caused by
a damaged or stuck roller in the spider assembly.
See "Roller, Pin and Thrust Washer Inspection".

Bearing Inspection

1. Rotate the clutch bearing in both clockwise and counter-
clockwise directions. The one-way bearing should rotate
counter-clockwise (when viewed from cover plate side)
with only a slight amount of drag. When rotated clockwise
the one-way bearing should lock to the shaft without
slipping.
2. Verify there is no binding or rough spots. If problems are
noted continue with disassembly.
