2. Replace switch if it fails tests in step 1.
e. Installation
1. Connect the wires as they were tagged during
switch removal.
2. Position the switch from under the right front
console panel.
3. Install the switch and carefully tighten the hex
nut.
4. Connect negative (–) cable (2, Fig. 10.38) to
the batteries.
5. Test switch for proper operation:
• UP for 4 wheel steer
• CENTER for 2 wheel steer
• DOWN for crab steer
If operation is not correct rotate switch or
reconnect wires.

Fig. 10.46 Typical Steer-Select Solenoid-Operated
Valve
10.7.8 Steer Select Solenoid
The steer select valve is a direct solenoid-oper-
ated spool-type directional control valve. It
controls the start, stop and direction of fluid flow to
the steering cylinders. It is located on the valve
plate assembly which is mounted under the
operator’s cab.
The valve consists of a housing (1, Fig. 10.46),
two solenoids (2), a control spool (3) and two
return springs (4).
In the de-energized condition, the spool (3) is held
by the return springs (4) in the center position.
The spool is shifted by energizing wet pin sole-
noids (2).
The force of the solenoid (2) pushes against push
pin (5) on the end of spool (3). The spool is
shifted from its normal position to the desired end
position. This selects the desired flow pattern of P
to A and B to T, or P to B and A to T. When the
solenoid (2) is de-energized, the control spool (3)
is returned to its normal condition by the centering
springs (4).
A manual override (6) is provided for emergency
operation of the valve (without electrical power).
The valve is supplied with a rubber boot covered
thumb button type manual override.
10.8 GAUGES AND INDICATOR
LIGHTS
The gauge cluster contains an hourmeter, warning
lights and a fuel level gauge. Removal and
installation instructions for the gauge cluster are
provided in paragraphs 10.47 and 10.48.
10.8.1 Removal of the Gauge Cluster
1. Disconnect negative (–) cable (2, Fig. 10.38)
from the batteries.
2. Remove four hex nuts (1, Fig. 10.47) and lock
washers (2) which secure gauge mounting
plate (3) and gauge cover (4) to right console
panel (5) and remove the four hex head
screws (6) from the panel. Carefully break the
rubber seal around the gauge mounting plate
and cover and separate the plate and cover.
3. Service the gauge cluster as described in the
following procedures for servicing of a specific
component in the gauge cluster (refer to
paragraphs 10.8.3, 10.8.4, 10.8.7 and 10.8.8.
4. Temporarily insulate all exposed wiring if it
becomes necessary for you to connect the
battery ground cable before you complete the
removal and installation procedures.
10.8.2 Installation of Gauge Cluster
1. Clean gauge cover (4, Fig. 10.47).
2. Remove all old rubber sealant from gauge
mounting plate (3) and gauge cover (4).
3. Position cover over gauge mounting plate.
Examine the assembly for alignment and the
cover for cleanliness. Apply a bead of silicon
rubber sealing compound along the top and
bottom surface of the gauge mounting plate
