9.15.7 Steering
Certain steering functions are dependent upon electrical
operations as described below. Consult the Owners/
Operators Manual for further information related to steering.
a. Steer Select Switch
The steer select switch (Fig. 9-106, 1) is located on the
right side of the operator’s control panel. It is a three-
position switch that is pressed or “snapped” into a
rectangular switch bezel.
Figure 9-106 Steer Select Switch Positions
The three-position switch (Fig. 9-106, 1) is a single-pole,
double throw toggle switch that has three positions. It has
a multiple-connector plug on its underside that connects
to the cab wiring harness. Wiring from the plug connects
the switch with power from the fuse panel bus bar, and to
the operator’s instrument cluster and the steer select
solenoids on the vehicle.
Steer select solenoids are energized or de-energized
accordingly to provide the type of steering selected. The
switch allows four-wheel steer (Fig. 9-106, 2) (the rear
wheels turn opposite the front wheels), two-wheel
steer (3) (the front wheels only) or crab steer (4) (the rear
wheels turn in the same direction as the front wheels).
b. Steer Modes and Conditions
Four-Wheel Steer Mode
With the steer select switch (Fig. 9-106, 1) in
the lower position (Fig. 9-106, 2), the following
conditions must be met:
1. Front wheels (Fig. 9-107, 1) must steer in the
direction that the steering wheel is turned.
Figure 9-107 Four-Wheel Steer
2. Rear wheels (Fig. 9-107, 2) must steer in the
opposite direction from which the steering wheel is
turned. (Refer to Section 9.7.16, “Four-Wheel Steer
Circuit and Troubleshooting.”)
