Removal (Fig. 98)
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.
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 the hydraulic hoses to
show their correct position on the lift cylinder for assem-
bly purposes.
5. Remove one (1) retaining ring and washer from the
cylinder pin (item 16) that secures the lift cylinder rod
clevis to the lift arm. Remove pin from lift arm and cylin-
der shaft clevis.
6. Remove one (1) retaining ring from the cylinder pin
(item 5) that secures the lift cylinder barrel clevis to the
frame. Remove cylinder pin from the 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. 98)
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).

3. Position cylinder rod end to lift arm and insert cylin-
der pin (item 16) with one (1) retaining ring and washer
installed through the lift arm and cylinder rod clevis. Se-
cure 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.
