DRIVE CLUTCH CLEANING AND INSPECTION
1.
Use a dry, lint-free cloth to clean clutch parts.
CAUTION
• Do not lubricate the drive clutch. Lubricants attract dirt and dust, which interfere with proper clutch
operation.
• Use only a dry cloth to lightly wipe the shaft of the fixed face assembly (7) (Figure 21-5, Page 21-6). Do
not use a brush or steel wool. These will damage the surface of the shaft.
• Do not use solvents. Solvents will damage the lubricating characteristics of the bushings.
2.
Inspect the belt contact surfaces of the clutch sheaves for wear. If any area of a sheave contact surface has
wear of 0.060 inch (1.52 mm) or more, the clutch should be replaced.
