MAINTENANCE
Clutch System
Periodically inspect clutch sheaves for damage, wear or belt residue. To
maintain optimum performance, clean with non-oil based cleaners such
as isopropyl alcohol.
WARNING! If you become aware of higher than normal clutch engagement or
an unusual vibration or shift pattern, see your dealer immediately. Do not
operate the snowmobile until repairs have been made.
All clutch maintenance and repairs must be performed by an authorized
POLARIS dealer. Any unauthorized modifications to clutches, such as
adding or removing weights, will void the warranty.
NOTICE: The bushings in the weights and rollers of POLARIS clutches are
made of a material that may be damaged if lubricated. Do not lubri-
cate clutch bushings.
Clutch Alignment Offset
Clutch alignment offset is important for maintaining optimum perfor-
mance. See your dealer for service and adjustments. A special tool is
required to check for proper alignment.
