Traction (Neutral) Switch Replacement and Adjustment (Fig. 16)
1. Pull connector off switch terminals of traction switch
installed in valve bank bonnet on selector valve section.
2. Loosen the jam nut and unscrew the switch from the
mounting bracket.
3. Move shift selector to Neutral.
4. Partially screw new switch into bonnet.
5. Connect a continuity tester or ohm meter to the switch
terminals and continue to turn the switch in until there is
continuity. Then rotate switch in 1/2 turn (180°).
6. Secure jam nut to 75 in.-lb (8.5 Nm) against the
bonnet.
IMPORTANT: Switch threads will be damaged if the
jam nut is over-tightened.
7. Connect continuity tester or ohm meter to switch
terminals and move shift selector to the No. 1 and No.
2 positions. There should not be continuity when shift
selector is in either of these positions. If there is conti-
nuity, repeat steps 4 and 5.
8. Move the shift selector lever to Neutral and connect
continuity tester or ohm meter to switch terminals. The
switch should show continuity. This means the switch is
operating correctly.
9. Fill terminal end of switch and wiring harness cover
with skin-over grease and push connectors onto switch
terminals.
