Driver-Controlled Main Differential Lock
MAINTENANCE MANUAL
10. Engage the splines of the collar with the
splines of the main differential case. Insert the
manual engaging capscrew through the top
of the shift cylinder to move the shift collar to-
ward the differential case. Rotate the collar as
necessary to align the splines. Figure 6.22.
11.Turn the manual adjusting capscrew to the
right until the head is approximately 0.25-inch
(6 mm) from the cylinder cover. Do not turn the
capscrew beyond its normal stop. The cap-
screw is now in the service position and the
main differential lock is completely engaged.
NOTE:
The differential must be in the locked position
to install the axle shaft into the axle housing.
12. With the shift collar in the locked position,
install the sensor switch into the threaded
hole in the front of the differential. Figure
6.23.
13. Connect a volt-ohm meter to the sensor
switch. Select ohms on the meter. With the
DCDL engaged, the circuit should be closed,
showing less than one ohm resistance. If the
resistance is over one ohm, check the sensor.
A. Verify that the fork is aligned with the sensor
switch when it is in the engaged position.
B. Check for a loose wiring connection. The con-
nector must be tightly seated.
C. Verify that the sensor switch is fully seated
against the differential.
