10. The control lever operates in a cam-over fash-
ion, with an extension spring and pivot link
between the control lever and the cable.
11. Remove the console cover / cup holder to gain
access to the control lever connection.
See Figure 3.8.
11a. Remove the knob from the Hurst gear
shift by turning it counter-clockwise.
11b. Remove the grip from the differential lock
control lever by pulling upward from the
base of the grip. A blow gun may be used
to force the grip off of the lever by shoot-
ing compressed air into the hole at the top
of the grip while lifting upward.
11c. Unbolt the console cover / cup holder
using a 9/16” wrench to remove the two
screws that hold the back of the console
cover. A 9/16” wrench can also be used
to loosen the two screws that secure the
front edge of the cover through slotted
holes.
11d. Lift the cover off to remove it.
12. When the differential lock is released, the pivot
link is held horizontal by spring tension.
See Figure 3.9.
13. When the differential lock is engaged, the pivot
link is pulled up and forward. See Figure 13.0.
• The connection point where the link is bolted to
the lever moves above the fulcrum point of the
lever.
• The curvature of the link brings the connection
point to the spring above the fulcrum point as
well.
• This locks the linkage into the engaged position
until the lever is moved by the operator.
