Service Brake Switch Adjustment
The service brake switch may be adjusted as required by
loosening the jam nut and positioning the switch so that
the brake switch does not activate until the pedal arm
moves a minimum of 1/8” (3,2mm). Tighten the jam nut
after adjusting the position of the switch in relation to
pedal travel.
10.8.10 Transmission Shift Control Switch
(Travel Select Lever)
The transmission shift control switch (travel select lever)
is located on the left side of the steering column. The
switch has three positions (Fig. 10– 67): FORWARD (F, all
the way up), NEUTRAL (N, center position), and
REVERSE (R, all the way down). The switch or lever
must be in the NEUTRAL (N) position to permit engine
starting.
Figure 10– 67. The travel select lever has three positions.
Moving the lever opens and closes electrical contacts in
the switch, allowing electricity to flow to the appropriate
relays and on to the transmission shift solenoids.
Travel selections are changed by grasping the lever, pull-
ing it toward the steering wheel, then UP or DOWN to the
desired selection, FORWARD (F) or REVERSE (R).
When the switch is shifted to the REVERSE (R) position,
the back-up alarm will automatically sound.

Gear Select Lever (switch)
The gear select lever (Fig. 10– 68) is part of the transmis-
sion shift control switch (travel select lever). The lever has
a twist-grip handle with four positions, although only
three may be used, depending on the engine the vehicle
is equipped with and on the direction the transmission
shift lever (gear select lever) has engaged.
Figure 10– 68. The gear select lever permits transmission
gear selection (shifting).
Vehicles equipped with the Perkins naturally aspirated
(non-turbo) engine have three (3) forward gears and
three (3) reverse gears. Placing the gear select lever into
the fourth position when in forward will have no effect on
vehicle speed.
Vehicles equipped with either the Perkins turbo-charged
engine or Cummins turbo-charged engine have four (4)
forward gears and three (3) reverse gears.
First gear is used for the highest torque and pulling
power, and the higher-numbered gears are for increasing
vehicle travel speed.
