Traction Neutral Sensor

The traction neutral sensor is a normally open proximity
sensor that closes when the traction pedal is in the neu-
tral position. The sensor mounts to a bracket on the trac-
tion speed control shaft (Fig. 15). The sensing plate for
the traction neutral sensor is the head of the socket head
screw that secures the ball bearings to the neutral cen-
tering arm assembly.
Adjustment
1. Before adjusting the traction neutral sensor, check
and adjust traction system neutral position (see Traction
Unit Operator's Manual).
2. Loosen both jam nuts that secure neutral sensor to
speed control bracket.
3. Adjust location of neutral sensor:
A. Manually lift sensor and adjust lower nut until LED
on cable end of traction neutral sensor is not illumi-
nated.
B. While still lifting sensor, rotate lower nut in the op-
posite direction until LED is illuminated. Then, rotate
lower nut in the same direction an additional one (1)
full turn.
C. Tighten upper nut to secure sensor. Make sure
that sensor position does not change. Jam nut
should be torqued from 162 to 198 in- -lb (18.4 to
22.4 N- -m).
IMPORTANT: To prevent traction neutral sensor
damage, make sure that sensor does not contact
any machine components during traction pedal
movement.
4. After adjustment to the traction neutral sensor, use
the Diagnostic Display (4WD machine) or the SCM
(2WD machines) to verify that traction neutral sensor
and circuit wiring are functioning correctly (see Traction
Neutral Sensor in the Component Testing section of this
chapter).
