Idler Arm Assembly Service
Refer to Figures C-23 through C-25 for transmission-
specific parks breakdowns.
The idler arm assembly is a pivoting, spring-loaded
mounting plate with pulleys that acts as a clutch/brake to
engage and disengage the main drive belt.
1. Remove the cotter pin and washer that secure the
rear end of the clutch rod to the idler arm (Figure
C–18). (The clutch rod and rod guide can be left in
place while the idler arm assembly is being serviced.)
2. Disengage the drive spring from the underside of the
frame to release tension on the idler arm assembly,
and remove.
3. See Figure C–19. Note the position of the belt stop
relative to the v-pulley, and then loosen the lock nut
that secures the v-pulley to the idler. Slide the drive
belt out of the gap between the pulley and belt stop.
4. See Figure C–20. 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.
5. Inspect the idler arm assembly for wear, cracked pul-
leys, or other damage, and replace parts as
required. Refer to Figure C–6 for proper assembly
position.
6. If service is to be performed on lockout lever or shift
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 stop
from moving.
