Belt to Sheave Clearance Inspection

NOTE: The distance between the belt and the moveable
sheave on the drive clutch is very important. This dis-
tance controls the starting ratio (lowest starting ratio is
most preferable) and the position of the clutch weight to
engine RPM. The distance between the belt and move-
able sheave should be as close to .020 (.5 mm) as pos-
sible without creating a drag on the belt, when positioned
around the hub at the bottom of the sheaves.
1. Force belt to one side of drive clutch.
Measure total belt to sheave clearance with a new
belt.
2. Install feeler gage between other sheave and belt.

Belt to Sheave Clearance Adjustment

Belt to sheave clearance can be adjusted in two ways.
1. Try several new belts to achieve proper clearance.
2. Can add or remove shims from under the spider to
increase or decrease belt to sheave clearance. See
Spider indexing on page 4.28.
NOTE: Spider indexing affects clutch balance and belt
to sheave clearance. Read procedures carefully before
proceeding.
NOTE: Belts with various widths will also affect belt
deflection since they will fit differently in the driven clutch.
Deflection should be checked per procedure on page
4.38.
