Centrifugal Clutches

Three measurements find your clutch: the shaft hole, the size across and the belt. Pick what you know below and the list narrows as you go.

Clutch finder

SHAFT HOLE
Step 1
Shaft hole
Measure the hole, or the engine shaft it slides onto. 3/4" is 19 mm, 1" is 25.4 mm.
Know your engine?
Step 2
Size across
Measure straight across the widest part of the old clutch, edge to edge.

Step 3
Belt size and number of belts
Count the grooves on the clutch: one or two. Then measure across the top of your belt, or across the top of one groove.

Machine-specific clutches

These are made for one machine family, so they are found by model, not by measurement.
