Removal (Fig. 88)
1. Park the machine on a level surface, engage the
parking brake, lower the cutting units and stop the en-
gine. Remove the key from the ignition switch.
2. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of the Service and Repairs section of this chapter.
3. Label all hydraulic connections for assembly pur-
poses. Thoroughly clean hydraulic connections prior to
loosening hydraulic lines from lift cylinder.
CAUTION
Before openinghydraulic system, operateall hy-
draulic controls to relieve system pressure and
avoid injury from pressurized hydraulic oil. See
Relieving HydraulicSystemPressure inthe Gen-
eral Information section of this chapter.
4. Disconnect hydraulic hoses from fittings in lift cylin-
derthatistoberemoved.Allowhosesto drainintoasuit-
able container. Remove and discard O--rings.
5. Putcaps orplugs ondisconnectedhoses andfittings
to prevent contamination.
6. Removeoneretainingring(item11)andthrustwash-
er (item 12) from the cylinder slide pin (item 13).Pull pin
fromtheliftcylinderand liftarm.Locateandretrievesec-
ond thrust washer.
7. Remove flange head screw (item 3) and flat washer
(item 5) that retain lift cylinder to pivot shaft.
8. Remove lift cylinder from pivot shaft and frame.
9. If hydraulic fittings are to be removed from lift cylin-
der, mark fitting orientation to allow correct assembly.
Remove fittings from lift cylinder and discard O--rings.
Installation (Fig. 88)
1. Ifhydraulicfittingswereremovedfromliftcylinder,lu-
bricate new O--rings, position O--rings to fittings and
installfittings intolift cylinderports (seeHydraulic Fitting
Installation in the General Information section of this
chapter).Make surethatfittings areorientatedcorrectly.
2. Position lift cylinder to the frame with the barrel end
up.
3. Slidelift cylinderclevisonto pivotshaft.Securecylin-
derwithflange headscrew(item3)and flatwasher(item
5). Torque screw from 67 to 83 ft--lb (91 to 112 N--m).
4. Align lift cylinder tolift arm mounting slot. Slide cylin-
der slide pin (item 13) with thrust washer (item 12)
through the liftcylinder and lift arm.Install second thrust
washer on pin and secure with retaining ring (item 11).
5. Remove caps and plugs from disconnected hoses
and fittings.
6. Coat new O--rings lightly with clean hydraulic oil,
install new O--rings and connect hydraulic hoses to fit-
tings on lift cylinder. Tighten hose connections.
7. Check oillevel in hydraulic reservoirand add correct
oil if necessary.
8. Lubricate lift cylinder grease fittings.
9. Follow Hydraulic System Start--up procedures (see
Hydraulic System Start--up in this section).
