Installation (Fig. 132)
1. If hydraulic fittings were removed from steering cylin-
der, lubricate new O--rings with clean hydraulic oil, posi-
tion O--rings to fittings and install fittings into steering
cylinder ports (see Hydraulic Fitting Installation in the
General Information section of this chapter).
2. If removed, press ball joint (item 10) into barrel and
secure with retaining ring.
3. If rod end (item 12) was removed from steering cylin-
der shaft, thread rod end into shaft so that distance from
end of shaft to center of grease fitting in rod end is 1.750"
(44.5 mm) (Fig. 134). Torque jam nut from 83 to 101 ft- -
lb (113 to 136 N- -m). Make sure that distance from end
of shaft to center of grease fitting doesn't change during
jam nut tightening.
4. Thoroughly clean tapers on ball joint, rod end and
axle assembly.
NOTE: Front axle steering cylinder should be installed
so ports are on the upper side. Rear axle steering cylin-
der should be installed so ports are on the lower side.
5. Position steering cylinder to machine.
