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 (Fig. 14). The sensing plate for the traction
neutral switch is the traction lever bracket that is secured
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 traction lever bracket does
not contact switch.
2. When the traction lever is in the neutral position, the
gap between the head of neutral switch and the traction
lever bracket should be from 0.070" to 0.100" (1.8 to 2.5
mm) (Fig. 15).
3. If gap is incorrect, loosen jam nuts that secure neu-
tral switch to pump bracket. Position switch with jam
nuts to allow correct gap between switch and traction le-
ver bracket. Jam nuts should be torqued from 162 to
198 in- -lb (18.4 to 22.4 N- -m). After jam nuts are tight-
ened, make sure that clearance between head of neu-
tral switch and traction lever bracket 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
are functioning correctly (see Traction Neutral Switch in
the Component Testing section of this chapter).
