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
machine 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.
CAUTION
The bushings in the weights and rollers of Polaris clutches are made of a
material that may be damaged if lubricated. Do not lubricate clutch bushings.
