hydraulic fittings at the lift cylinder. Allow hoses to drain
into a suitable container.
4. Remove cotter pin and clevis pin that secure the lift
cylinder clevis to the lift arm.
5. Support lift cylinder to prevent it from dropping.
A. Remove cap screw and washer from the pivot pin

Front Lift Cylinder Installation (Fig. 62)
1. If fittings were removed from lift cylinder, lubricate
and place new O--rings onto fittings. Install fittings into
lift cylinder ports. Tighten fittings (see Hydraulic Fitting
Installation in the General Information section of this
chapter).
2. Position lift cylinder to the machine.
3. Insert pivot pin (item 8) through the outer frame
bracket, thinner spacer, lift cylinder, thicker spacer and
inner frame bracket. Secure pin to frame with cap screw
and washer.
4. Position clevis of the lift cylinder to the lift arm. Se-
cure lift cylinder clevis to the lift arm with clevis pin and
cotter pin.
5. Connect hydraulic hoses with new O--rings to the hy-
draulic fittings on the lift cylinder. Tighten hose connec-
tions (see Hydraulic Hose and Tube Installation in the
General Information section of this chapter).
6. Make sure that hydraulic reservoir is at correct level.
7. Start machine. Run machine at idle for several min-
utes to circulate hydraulic fluid and remove any air
trapped in the system. Stop machine and recheck hy-
draulic reservoir level.
