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 or qualified person immediately. Do
not operate the snowmobile until repairs have been made.
All clutch maintenance and repairs can 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 lubricate clutch bushings.
CLUTCH ALIGNMENT OFFSET
Clutch alignment offset is important for maintaining optimum performance. Your
dealer can assist with service and adjustments. A special tool is required to
check for proper alignment.
DRIVE BELT CONDITION
Periodically check the condition and tension of the drive belt. Inspect the belt for
signs of excessive wear (frayed edges, missing cogs, cracks) and excessive
looseness. Replace the belt if any of these conditions exist. See page 220.
Always carry a spare drive belt. Store the spare belt in the belt holder. When
placing the belt in the holder, orientate the belt to match the profile of the hood.
For improved drive-away during extremely cold temperatures, remove the belt
and warm it to room temperature. Reinstall it before starting the snowmobile.
