able container.
6. Put clean caps or plugs on disconnected hoses and
fittings to prevent contamination.
7. Support steering cylinder to prevent it from falling.
8. Remove jam nuts that secure cylinder ball joints to
frame and rear fork assembly.
9. Separate cylinder ball joints from frame and rear
fork. Remove steering cylinder from machine. Locate
and retrieve cylinder spacer (item 10).
10.If necessary, remove hydraulic fittings from steering
cylinder and discard O--rings.
11.If necessary, remove ball joints from steering cylin-
der. Discard removed ball joints.
Installation (Fig. 75)
1. If ball joints were removed from steering cylinder,
press new ball joints into steering cylinder and secure
with retaining rings.
2. If fittings were removedfromsteering cylinder, lubri-
cate and place new O--rings onto fittings. Install fittings
intocylinderportopenings.Tightenfittings(seeHydrau-
lic Fitting Installation in the General Information section
of this chapter).
3. Thoroughly cleantaperedsurfaces ofsteeringcylin-
der ball joints and cylinder attachment bores on ma-
chine.
4. Place cylinder spacer (item 10) onto cylinder barrel
ball joint.
5. Insertballjointsofcylinder intoattachmentpointson
frame and rear fork assembly.
6. Secure both steering cylinder ball joints to machine
with two (2) jam nuts (item 4). Install first jam nut and
torquefrom60to80 ft--lb(82 to 108N--m).Then,while
holdingfirstjamnutwithwrench,tightensecondjamnut
and torque from 60 to 80 ft--lb (82 to 108 N--m).
7. Remove caps and plugs from disconnected hoses
and fittings.
8. LubricatenewO--ringsandconnect hydraulichoses
to steering cylinder(Fig. 76). Tighten hose connections
(seeHydraulicHoseandTubeInstallationintheGener-
al Information section of this chapter).
9. Lower and secure tank mount plate assembly (hy-
draulic reservoir, fuel tank and tank mount plate) (see
Tank Mount Plate Assembly in the Service andRepairs
section of Chapter 7 -- Chassis).
10.Check fluid levelinhydraulic oil reservoirandadjust
