Removal (Fig. 96)
1. Park machine on a level surface, lower cutting units,
stop engine, engage parking brake and remove key
from the ignition switch.
2. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of this chapter.
3. To prevent contamination of hydraulic system during
lift cylinder removal, thoroughly clean exterior of lift cyl-
inder that is to be removed from machine.
WARNING
Make sure that cutting units are fully lowered be-
fore loosening hydraulic lines from lift cylinder. If
cutting units are raised as hydraulic lines are
loosened, cutting units may drop unexpectedly.
4. Disconnect hydraulic hoses from lift cylinder. Put
caps or plugs on open hydraulic lines and fittings to pre-
vent system contamination. Label disconnected hy-
draulic lines for proper assembly.
5. Remove one (1) retaining ring and washer from the
cylinder pin (item 8). Remove cylinder pin from the lift
arm and cylinder rod clevis which will free lift cylinder
from lift arm.
6. Remove flange nut and flange head screw that se-
cure the cylinder pin (item 16) to the frame. Pull pin from
frame and cylinder barrel clevis.
7. Remove lift cylinder from machine.
8. If hydraulic fittings are to be removed from lift cylin-
der, mark fitting orientation to allow correct assembly.
Remove fittings from cylinder and discard O- rings.

Installation (Fig. 96)
1. If fittings were removed from lift cylinder, lubricate
and place new O- rings onto fittings. Install fittings into
cylinder openings using marks made during the removal
process to properly orientate fittings. Tighten fittings
(see Hydraulic Fitting Installation in this chapter).
2. Position lift cylinder barrel end to frame and insert
cylinder pin (item 14) into frame and cylinder. Secure pin
with flange nut and flange head screw.
3. Position cylinder rod clevis to lift arm and insert cylin-
der pin (item 8) with one (1) retaining ring and washer
installed through the lift arm and cylinder clevis. Secure
pin with second washer and retaining ring. Make sure
that retaining ring is fully seated in pin.
4. Remove caps and plugs from hoses and fittings. At-
tach hydraulic hoses to lift cylinder (see Hydraulic Hose
and Tube Installation in this chapter).
5. Fill reservoir with hydraulic fluid as required (see
traction unit Operator's Manual).
6. Follow hydraulic system start- up procedures (see
Charge Hydraulic System in this chapter).
7. After assembly is completed, operate lift cylinder to
verify that nothing contacts the hydraulic hoses and fit-
tings during operation.
