Primary Clutch Inspection
NOTE: If primary clutch wear or damage occurs, clutch
replacement may be necessary. Refer to your parts cat-
alog to identify individual primary clutch components
that are available.
1. Inspect the tapered ends of the engine crankshaft
and stationary sheave of primary clutch. If either is se-
verely damaged, replace component as damage to the
taper will allow loosening of the clutch during vehicle op-
eration.
2. Check all of the rollers, button plugs and primary but-
tons. If binding or uneven wear is found, replace all roll-
ers, plugs and buttons as a set.
3. Check the contact surface of the moveable sheave
for wear and/or fraying. If surface is worn/frayed, re-
place component.
