How to Clean Snowmobile Clutches

One of the most important and easiest ways to increase and maintain the power and performance of a snowmobile is to perform regular clutch maintenance. Several parts make up the clutch assembly. One of the major parts requiring regular cleaning is the primary and secondary clutch surface. Grease and oil can contaminate the surface, resulting in slippage and loss of power. Clean and adjust the clutch assembly each season, or every 1,000 miles.
