8. Inspect bushings in lift arm and pivot yoke for wear
or damage. If necessary, replace bushings (Figs. 22 and
23).
A. Use bushing removal tool to extract bushings
from the lift arm or pivot yoke. Take care to not dam-
age the bore.
B. Clean the inside of the bore to remove any dirt or
foreign material.
C. Apply grease to the inside and outside of the new
bushings.
D. Use an arbor press to install the bushings into lift
arm or pivot yoke. Lift arm bushings should be
pressed until bushing flange is against lift arm bore.
The upper pivot yoke bushing should be pressed ful-
ly to the shoulder in the pivot yoke bore. The lower
pivot yoke bushing should be flush with the yoke
tube.
9. Check lift arm pivot shaft (item 4) for wear or dam-
age. If necessary, remove roll pin (item 5) that secures
pivot shaft to frame and remove pivot shaft. Discard re-
moved roll pin.
Installation (Fig. 20)
1. If lift arm pivot shaft (item 4) was removed from
frame, apply antiseize lubricant to portion of pivot shaft
that is in frame bore. Slide pivot shaft into frame and se-
cure with new roll pin (item 5).
2. Slide front lift arm onto pivot shaft.
3. Apply medium strength threadlocker to threads of
cap screws (items 7, 9 and 21) that secure bridge plate
(items 8 and 17). Secure lift arm to machine with bridge
plate. Torque cap screws that secure bridge plate to
torque values identified in Figure 20.
4. Position thrust washer (item 15) onto pivot yoke shaft
and then slide pivot yoke into lift arm bushings. Place
second thrust washer on pivot yoke shaft and secure
with lynch pin (item 14).
5. Align lift cylinder to lift arm mounting slot (Fig. 21).
Slide cylinder slide pin (item 5 in Fig. 21) with retaining
ring (item 3 in Fig. 21) and thrust washer (item 4 in Fig.
21) through the lift arm and lift cylinder. Install second
thrust washer on pin and secure with second retaining
ring.
6. Mount cutting unit to lift arm.
7. Lubricate grease fittings on lift arm, pivot yoke and lift
