Traction Neutral Switch - Toro Sand Pro 5040 Service Manual

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 is attached to the hydrostat
pump plate (Fig. 16). A cap screw located on the neutral
arm acts as the sensing plate for the switch.
Testing
1. Park machine on a level surface, lower attachment,
stop engine, apply parking brake and remove key from
ignition switch.
2. Remove center shroud to allow access to traction
neutral switch (Fig. 17).
3. Locate traction neutral switch for testing.
4. Disconnect the wire harness electrical connector
from the neutral switch.
5. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the switch connector
terminals.
6. With the ignition switch in the OFF position, slowly
push the traction pedal in the forward and reverse direc-
tion while watching the multimeter. Continuity should be
broken in both the forward and reverse directions.
7. Allow the traction pedal to return to the neutral posi-
tion. There should be continuity across the terminals
when the pedal is in neutral.
8. Connect the electrical connector to the switch.
9. Install center shroud to machine (Fig. 17).
Adjustment (Fig. 16)
1. Before adjusting the traction neutral switch, check
and adjust traction system neutral position (see Opera-
tor's Manual).
IMPORTANT: To prevent traction neutral switch
damage, make sure that end of cap screw does not
contact switch.
2. Loosen jam nut on cap screw.
3. With traction pedal in the neutral position, rotate cap
screw so the clearance between head of the screw and
neutral switch is .030" to .090" (.8 to 2.2 mm).
4. Tighten jam nut on cap screw to secure adjustment.
After jam nut is tightened, make sure that clearance be-
tween cap screw and neutral switch has not changed.
5. Check for proper switch operation (see Testing
above).
