Removal (Fig. 108)
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
(or implement), stop engine, engage parking brake and
remove key from the ignition switch.
2. Thoroughly clean hydraulic hose ends and fittings on
lift cylinder to prevent hydraulic system contamination.
3. Label hydraulic hoses for assembly purposes. Also,
label orientation of hydraulic hose at barrel end of lift cyl-
inder to allow correct assembly.
4. Disconnect hydraulic hoses connected to the hy-
draulic fittings on the lift cylinder. Install clean plugs in
hose openings to prevent system contamination.
5. Remove retaining ring that secures lift cylinder barrel
end to pin on carrier frame.
6. Remove flange head screw and pivot pin that secure
lift cylinder rod end to RH lift arm (Fig. 109).
7. Remove lift cylinder from machine.
8. If necessary, remove hydraulic fittings from lift cylin-
der. Remove and discard O- rings from fittings. Note that
fitting on barrel end of cylinder is an orifice fitting that is
different than fitting on rod end of cylinder.
Installation (Fig. 108)
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.
3. Secure cylinder barrel end to pin on carrier frame
with retaining ring.
4. Secure cylinder rod end to RH lift arm with pivot pin
and flange head screw (Fig. 109).

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.
