Adjustments
Traction Neutral Switch
The traction neutral switch is a normally open proximity
switch that closes when the traction pedal is in the neu-
tral position. The switch mounts to a bracket on the trac-
tion pump. On machines with serial numbers below
310000000 (Fig. 17), the sensing element for the trac-
tion neutral switch is a cap screw on the pump control
arm. On machines with serial numbers above
310000000 (Fig. 18), the sensing element for the trac-
tion neutral switch is the traction lever bracket that is se-
cured to the pump control arm.
Adjustment
1. Before adjusting the traction neutral switch, check
and adjust traction system neutral position (see Traction
Unit Operator’s Manual).
IMPORTANT: To prevent traction neutral switch
damage, make sure that no components contact
switchthroughentirepumpcontrol armmovement.
2. For machines with serial numbers below 310000000
(Fig. 17), adjust traction neutral switch as follows:
A. Loosen jam nut that secures position of cap
screw on pump control arm.
B. Rotate cap screw so clearance exists between
head of the screw and neutral switch body but clear-
ance is less than 0.125” (3.2 mm).
C. Torque jam nut from 71to 89in--lb(8 to10 N--m)
to secure adjustment. After jam nut is tightened,
make sure that clearance between cap screw head
and neutral switch has not changed.
3. For machines with serial numbers above 310000000
(Fig. 18), adjust traction neutral switch as follows:
A. When the traction lever is in the neutral position,
the clearance between the head of neutral switch
and the traction lever bracket should be from 0.040”
to 0.100” (1.1 to 2.5 mm).
B. If clearance is incorrect, loosen jam nuts that se-
cure neutral switch to pump bracket. Position switch
with jam nuts to allow correct clearance between
switch and traction lever bracket. Jam nuts should be
torqued from 162 to 198 in--lb (18.4 to 22.4 N--m).
After jam nuts are tightened, make sure that clear-
ance has not changed.
4. After adjustment to the traction neutral switch, use
the Diagnostic Display (see Special Tools in this chap-
ter) to verify that traction neutral switch and circuit wiring
arefunctioning correctly (see Traction Neutral Switch in
the Component Testing s ection of this chapter).
