NOTICE: Note that the factory applies a thread seal-
ant to the accelerator rod threads before threading
the rod into the clevis.
Fig. 7 Accelerator Pedal Arm Adjustment
Micro Switch Adjustment
When the system is in correct adjustment, the micro
switch in the accelerator pedal box will click when the top
of the accelerator pedal moves approximately 1/2" - 5/8"
(13 - 16 mm). The accelerator cable (as seen at the rear
axle) should have some slack present and not show any
movement until after the micro switch clicks.
To access the micro switch, remove the rocker panel, lift
the floor mat and remove the access cover from the floor
(Ref. Fig. 3). Remove the screws (8) and cover (7) from
Fig. 8 Pedal Box Micro Switch
Loosen the setscrew (9) in cam (10) using an 1/8" Allen
wrench. Loosen the jam nut (12) and move the cam to
adjust as needed (Ref. Fig. 8). Adjust to permit 1/2" - 5/8"
(13 - 16 mm) of accelerator pedal travel before the micro
switch (11) clicks. Measure the distance at the top of the
pedal with the pedal arm contacting the pedal bracket.
Making sure the setscrew in the cam does not contact the
micro switch actuator. Tighten the setscrew (9) and the
jam nut (12) to the specified torque.
Be sure the accelerator pedal moves smoothly and the
accelerator cable pulls smoothly on the governor arm.
Replace the cover on the pedal box. Tap lightly to set the
cover before installing screws. Replace the access cover
on the floor. Replace floormat and rocker panel.
Road Test
Install the negative (-) battery cable.
Test drive the vehicle and confirm that the compression
spring adjustment results in the maximum governed
speed specified in the GENERAL SPECIFICATIONS sec-
tion. Determine speed by measuring the time it takes to
travel a known set distance with vehicle at maximum
speed. Enter time and distance into this formula to calcu-
late speed:
Rate (in MPH) = (Distance in feet / 5280) /
(Time in seconds / 3600)
or
Rate (in KPH) = (Distance
in meters / 1000) / (Time in seconds / 3600)
. For exam-
ple: (300 ft. / 5280) / (13.6 sec. / 3600) = 15 MPH or (100
m / 1000) / (15 sec. / 3600) = 24 KPH. If the speed is not
within the specified speed range, stop the vehicle and
adjust the governor compression spring as described in
procedure above.
Repeat the test and adjustment until the factory recom-
mended governed speed is achieved. Tightening the
spring results in a speed increase while loosening it will
result in a speed decrease.
