Adjust Rear Lift Arm - Toro 30821 Service Manual

Adjust Rear Lift Arm

1. Park machine on a level surface and engage parking
brake.
IMPORTANT: This adjustment must be performed
with the rear cutting unit attached to the rear lift arm.
2. Raise lift arms. Make sure clearance between wear
strap on the top of the rear cutting unit wear bar and
bumper strap is from 0.020 to 0.100 inch (0.51 to 2.54
mm) (Fig. 8).
3. If the clearance is not in this range, attain proper
clearance by adjusting the rear hydraulic cylinder as fol-
lows (Fig. 9):
A. Lower cutting units, turn engine off, and remove
key from the ignition switch.
B. Back off jam nut from the rear hydraulic cylinder
clevis.
IMPORTANT: Use a protective covering around the
hydraulic cylinder rod when rotating the rod to pre-
vent damage to the rod.
C. Grasp cylinder rod near the jam nut and rotate the
rod.
D. Raise cutting units and check clearance. Repeat
steps A through C as necessary. Tighten jam nut on
hydraulic cylinder rod when clearance is correct.
NOTE: If rear lift arm makes clunking noises during
transport, the clearance can be reduced.
IMPORTANT: The lack of clearance at the rear wear
bar can damage the rear lift arm.
