5. Put caps or plugs on disconnected lines and fittings
to prevent contamination.
6. While supporting steering column to prevent it from
falling, loosen and remove four (4) carriage screws (item
8) and flange nuts (item 11) that secure steering column
assembly to machine. Locate and retrieve four (4) wash-
ers (item 10) and mounts (item 9).
7. While carefully guiding steering control valve from
hole in platform, lift steering column assembly (with
steering control valve attached) and remove from ma-
chine.
8. Place steering column assembly on bench. Slide
rubber bellows up from bottom of steering column.
9. Loosen and remove three (3) flange head screws
(item 12) and one (1) socket head screw (item 13) that
secure steering column to steering control valve. Note
location of socket head screw for assembly purposes.
10.Remove steering control valve (item 6), alignment
bushing (item 4) and steering plate (item 7) from steer-
ing column.
11. If necessary, remove fittings and O--rings from steer-
ing control valve (Fig. 128). Discard all removed O--
rings.
Installation (Fig. 127)
1. If fittings were removed from steering control valve,
lubricate new O--rings with clean hydraulic oil and install
fittings to control valve (see Hydraulic Fitting Installation
in the General Information section of this chapter).
2. Apply antiseize lubricant to splines of steering con-
trol valve input shaft.
3. Position alignment bushing (item 4) and steering
plate (item 7) to steering control valve and then slide
steering control valve input shaft onto steering column
shaft. Position control valve with ports toward tilt lever on
steering column. Make sure that alignment bushing is
positioned on steering control valve and into steering
plate bore.
4. Secure steering column in place with three (3) flange
head screws (item 12) and one (1) socket head screw
(item 13). Hand tighten screws in a crossing pattern and
then torque screws again in a crossing pattern from 34
to 42 ft- -lb (47 to 56 N- -m).
5. Carefully position steering column assembly to ma-
chine.
6. Position mounts (item 9) between frame and steer-
ing plate at four (4) mounting holes. Secure steering col-
umn assembly to machine with four (4) carriage screws
(item 8), washers (item 10) and flange nuts (item 11).

7. Remove caps and plugs from disconnected hydrau-
lic lines and fittings.
8. Lubricate new O--rings and connect hydraulic lines
to fittings on steering control valve using labels placed
during valve removal. Tighten all connections (see Hy-
draulic Hose and Tube Installation in the General Infor-
mation section of this chapter).
9. Slide rubber bellows to bottom of steering column.
10.Check oil level in hydraulic reservoir and add correct
oil if necessary.
11. Follow Hydraulic System Start--up procedures (see
Hydraulic System Start--up in this section).
