Removing the Rear Lift Arms (continued)
Note: Do not damage the bore of the lift arm or pivot yoke during bushing
removal.
A. Use the bushing removal tool to extract both the bushings from the lift
arm or pivot yoke.
B. Clean the inside of the bore to remove any dirt or unwanted material.
C. Apply grease to the inner and outer surfaces of the new bushings.
D. Use an arbor press to install the bushings into the lift arm or pivot yoke.
The lift arm bushings should be pressed until the bushing flange is
against the lift arm bore. The upper pivot yoke bushing should be pressed
fully to the shoulder in the pivot yoke bore. The lower pivot yoke bushing
should be flush with the yoke tube.
Installing the Rear Lift Arms
1. Position the rear lift arm to the frame and slide the pivot shaft through
frame bosses and lift arm. Secure the shaft flange to the frame with the
washer-head screw.
2. Install the torsion springs and components that secure the springs to the
machine ( Figure 316 or Figure 318 ). Position the long leg of spring forward
and pointing out from top of the spring. On the machines that include a
housing to secure the torsion springs (shown in
Figure 316 ), the short leg of
the torsion springs should be against the stop on the housing.
3. Align the lift cylinder rod end to the lift arm mounting slot. Slide the cylinder
pin (item 4 in Figure 317 ) with the retaining ring and thrust washer through
the lift cylinder and lift arm. Install the second thrust washer on the pin and
secure with the second retaining ring.
CAUTION
Be careful when applying tension to the torsion spring on the rear lift
arms. The spring is under heavy load and may cause personal injury.
4. Apply tension to the torsion springs:
A. Insert a nut driver or small piece of pipe onto the long leg of the torsion
spring on the rear of the lift arm pivot pin.
B. Push down and forward on the spring end to hook the spring to the
shoulder stud on the lift arm. Ensure that the spring end is positioned on
stud as noted during disassembly.
5. Mount the cutting unit to the lift arm.
6. Lubricate the grease fittings on the lift arm, pivot yoke, and lift cylinder.
