Adjustments
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 right
side of the traction speed control shaft (Fig. 14 or 15).
On machines with serial number below 315000000 (Fig.
14), the sensing plate for the traction neutral sensor is
the head of the socket head screw that secures the ball
bearings to the neutral centering arm assembly. On ma-
chines with serial number above 315000000 (Fig. 15),
the neutral arm is used as the sensing plate.
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.
NOTE: On machines with serial number above
315000000 (Fig. 15), the gap between the neutral
sensor and the neutral arm should be from 0.110” to
0.140” (2.8 to 3.5 mm).
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).
