Removal (Fig. 90)
1. Park machine on a level surface, lower cutting deck,
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 beginning
of this section.
3. To prevent contamination of hydraulic system during
lift cylinder removal, thoroughly clean exterior of cylinder
and fittings.
NOTE: To ease installation, label the hydraulic hoses to
show their correct position on the lift cylinder.
4. Disconnect hydraulic hoses from lift cylinder.
5. Remove flange head screw and lock nut that secure
the pin to the lift arm. Remove pin from lift arm and cylinder
shaft clevis which will free lift cylinder from lift arm.
6. Remove one cotter pin from upper lift pin. Pull upper
lift pin from frame and cylinder barrel clevis.
7. Remove lift cylinder from machine.
8. If hydraulic fittings are to be removed from lift cylinder,
mark fitting orientation to allow correct assembly. Remove
fittings from cylinder and discard O--rings.
Installation (Fig. 90)
1. If fittings were removed from lift cylinder, lubricate
and place new O--rings onto fittings. Install fittings into
port openings using marks made during the removal
process to properly orientate fittings. Tighten fittings
(see Hydraulic Fitting Installation in the General Information
section of this chapter).
2. Position cylinder barrel clevis to frame and insert upper
lift pin into frame and clevis. Secure lift pin with cotter
pin.
3. Insert pin through lift arm and cylinder shaft clevis.
Secure pin to lift arm with flange head screw and lock
nut.
4. Attach hydraulic hoses to lift cylinder.
5. Fill reservoir with hydraulic fluid as required.
6. After assembly is completed, operate lift cylinder to
verify that hydraulic hoses and fittings are not contacted
by anything.
