Clutch Cable and V-Belt Adjustment (See Figure
12):
The clutch cable has an adjuster (located at
the end of the cable) to increase or decrease the V-
belt tension. If the V-belt is slipping when the clutch
handle is fully engaged, the V-belt tension needs to
be increased. If the clutch engages rapidly or “grabs”
when the clutch handle is slightly engaged, the V-
belt tension needs to be decreased. Also, decrease
the V-belt tension if the machine “creeps” forward
when the clutch is not engaged. Before adjusting,
inspect the V-belt, clutch cable, and the clutch cable
spring for damage and wear. Replace spring or V-
belt if proper operation cannot be reached with cable
adjustment. Check the engine mounting hardware
and the alignment of the pulleys. If the engine has
moved during operation, it will affect the adjustment
and operation of the clutch.
Step 1.
Ensure that the upper end of the clutch cable
is securely mounted to the clutch control handle.
Check the engine mounting hardware, the hardware
should be tight and engine pulley should be in line
with the clutch pulley.
Step 2.
Proper adjustment range is measured on the
spring at the cable end. The spring should stretch
1/2” to 3/4” from its original length when the clutch
handle is engaged.
Step 3.
Move adjuster in or out. Moving the cable end out
increases the tension - moving in decreases tension.
Tighten nuts to secure adjustment.
Step 4.
Test and repeat adjustment as needed.
NOTE:
Check the engine mounting hardware. If the
engine has moved during operation, it will affect the
adjustment and operation of the clutch. The engine
should be fully back (towards operator) in the slots in
the frame where the engine is mounted.
