hydraulic fittings at the lift cylinder. Allow hoses to drain
intoasuitablecontainer.
4. Support lift cylinder to prevent it from dropping.
A. Removecapscrew, washerandlocknutfrom the
pivotpin(item8).Pullpivotpinfromtheframeandlift
cylinder.
B. Remove cotterpinfrom clevispin(item 14).Slide
clevis pin from lift cylinder and lift arm.
C. Separate hydraulic cylinder from the frame and
lift a rm. Remove cylinder from machine.
5. If hydraulic fitting removal is necessary, matchmark

Center Cylinder Installation (Fig. 63)
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 frame brackets
andliftcylinder.Securepintoframewithcapscrew,
washer and lock nut.
4. Position clevis of the lift cylinder to the lift arm. Se-
cure liftcylinder clevisto the liftarm with clevispin (item
14) and cotter pin.
5. ConnecthydraulichoseswithnewO--ringstothehy-
draulic fittings on the lift cylinder. Tighten hose connec-
tions (see Hydraulic Hose andTubeInstallationinthe
General Information section of this chapter).
6. Make sure thathydraulic reservoir isat correctlevel.
