7. Disconnect hydraulic lines from steering control
valve. Allow lines to drain into a suitable container.
8. Put caps or plugs on disconnected lines and fittings
to prevent contamination.
9. Remove two (2) socket head screws and flange nuts

Installation (Fig. 77)
1. If fittings were removed, lubricate new O--rings with
clean hydraulic oil and install fittings to steering control
valve (see Hydraulic Fitting Installation in the General
Information section of this chapter).
2. Apply a ntiseize lubricant to splines of steering con-
trol valve shaft.
3. Slide steering control valve shaft into steering col-
umn universal joint. Position control valve with ports to-

quence, torque screws from 6 to 8 ft--lb (8 to 11 N--m).
5. Position steering column assembly to machine. Se-
cure steering column in place with two (2) socket head
screws and flange nuts at rear two mounting holes.
6. Remove caps and plugs from disconnected lines
and fittings.
7. Lubricate new O--rings and connect hydraulic lines
