Removal (Fig. 140)
WARNING
Before disconnecting or performing any work on
the hydraulic system, all pressure in the system
must be relieved. See Relieving Hydraulic System
Pressure in the General Information section.
1. Park machine on a level surface, lower cutting deck,
stop engine, engage parking brake and remove key
from the ignition switch.
WARNING
Make sure that cutting deck is fully lowered and
supported before loosening hydraulic lines from
lift cylinder. If deck is not supported as hydraulic
lines are loosened, deck may drop unexpectedly.
2. Make sure that cutting deck is supported by the HOC
pin and not by the lift cylinder so deck will remain in posi-
tion during lift cylinder removal. If necessary, support
deck with solid blocks to prevent it from moving.
3. Thoroughly clean hydraulic hose ends and fittings on
lift cylinder to prevent hydraulic system contamination.
4. Label hydraulic hoses for assembly purposes.
5. Disconnect hydraulic hoses connected to the hy-
draulic fittings on the lift cylinder. Install clean plugs on
fittings and hose openings to prevent system contami-
nation.
6. Remove one retaining ring (item 8) and washer (item
7) from the cylinder shaft (item 6) that secures lift cylin-
der barrel end to machine frame. Pull shaft from the lift
cylinder and frame. Locate and retrieve second washer.
7. Remove shoulder bolt (item 4) and pivot pin (item 2)
that secure lift cylinder rod end to lift shaft.
8. Remove lift cylinder from machine.
9. If necessary, remove hydraulic fittings from lift cylin-
der (Fig. 141). Remove and discard O--rings from fit-
tings. Note that fitting on barrel end of cylinder is an
orifice fitting that is different than fitting on rod end of cyl-
inder.

Installation (Fig. 140)
1. If hydraulic fittings were removed from lift cylinder, lu-
bricate and install new O--rings to fittings. Install fittings
into lift cylinder ports and torque fittings from 15 to 19 ft- -
lb (20 to 25 N- -m). Make sure that fitting on barrel end
of cylinder is the orifice fitting.
2. Position lift cylinder to the machine. The lift cylinder
barrel end should be attached to the machine frame.
3. Secure cylinder rod end to lift shaft with pivot pin
(item 2) and shoulder bolt (item 4).
4. Align lift cylinder to frame mounting holes. Slide cyl-
inder shaft (item 6) (with washer (item 7) and retaining
ring (item 8) installed on one end) through the lift cylinder
and frame. Install second washer on shaft and secure
with retaining ring (item 8).
5. Remove plugs that were installed in fittings and hy-
draulic hoses during the removal procedure. Correctly
connect hydraulic hoses to lift cylinder fittings using la-
bels placed during lift cylinder removal (see Hydraulic
Hose and Tube Installation in the General Information
section of this chapter).
6. Lubricate grease fittings on lift cylinder and pivot pin.
7. Make sure hydraulic tank is full. Add correct oil if nec-
essary.
8. Follow Hydraulic System Start--up procedures (see
Hydraulic System Start--up in this section).
