The idler arm assembly is a pivoting, spring-loaded
mounting plate with pulleys that acts as a clutch to
engage and disengage the main drive belt. It is also pro-
vides an attachment point for assembly of the clutch rod,
brake arm, and brake rod. See Figure C–3 for specific
assembly and part location information.

3. See Figure C–12. Slide the clip ring out of the
groove on the pivot shaft, and remove the idler arm
assembly from the unit by pulling it off the shaft.

leys, or other damage, and replace parts as required.
Refer to Figure C–13 for proper assembly position.

pivot assembly, proceed to next section. If no addi-
tional service is to be performed on idler arm assem-
bly, reassemble idler arm assembly parts in reverse
order of disassembly.
NOTE: Before tightening v-pulley locknut, reinstall drive
belt and position belt stop in original location. Hold belt
stop in position while tightening locknut to prevent belt
