Removal (Fig. 85)
1. Park machine on a level surface. Lower cutting units,
stop engine and engage parking brake. Remove key
from the ignition switch.
2. Read the General Precautions for Removing and
Installing Hydraulic System Components in this chapter.
3. To prevent contamination of hydraulic system during
lift cylinder removal, thoroughly clean exterior of cylin-
der and fittings.
WARNING
Make sure that the cutting units are fully lowered
before loosening hydraulic lines from lift cylin-
ders. If cutting units are not fully lowered as hy-
draulic lines are loosened, cutting units may
drop unexpectedly.
NOTE: To ease installation, label the hydraulic hoses to
show their correct position on the lift cylinder.
4. Disconnect hydraulic hoses from lift cylinder that is
to be removed.
5. Detach rod end of lift cylinder from lift arm. Remove
retaining ring and flat washer from one end of the cylin-
der pin and slide pin from lift arm and cylinder rod end.
6. Remove washer head screw that secures the pivot
pin to the frame and slide pivot pin from frame and cylin-
der.
7. Remove lift cylinder from machine.
8. If necessary, remove hydraulic fittings from lift cylin-
der and discard O−rings.
Installation (Fig. 85)
1. If fittings were removed from lift cylinder, lubricate
and place new O−rings onto fittings. Install fittings into
cylinder port openings using marks made during the re-
moval process to properly orientate fittings. Tighten fit-
tings (see Hydraulic Fitting Installation in this chapter).
2. Secure barrel end of cylinder to frame and slide pivot
pin into frame and cylinder. Secure pivot pin to frame
with washer head screw.
3. Make sure that flat washer and retaining ring are in-
stalled on one end of the cylinder pin.
4. Position cylinder rod end to lift arm and insert pin
through lift arm and cylinder rod end. Secure pin to lift
arm with second flat washer and retaining ring.
5. Attach hydraulic hoses to lift cylinder (see Hydraulic
Hose and Tube Installation in this chapter).
6. Fill reservoir with hydraulic fluid as required.
7. After installation is completed, operate lift cylinder to
verify cylinder, hydraulic hose and fitting clearance.
