9.14.8 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 (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.
The three-position switch (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 (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 (1) in the lower
position (2), the following conditions must be
met:
1. Front wheels (5) must steer in the direction that the
steering wheel is turned.
2. Rear wheels (6) must steer in the opposite direction
from which the steering wheel is turned. Refer to
Section 9.7.40, “Four-Wheel Steer Circuit and
Troubleshooting.”
