ADJUST UPPER ACCELERATOR DETENT PLUNGER
NOTE
Detent plunger is factory lubricated and adjusted for a force of 35 to 40 pounds to push plunger
through detent. If lubrication or repair is required, see REPLACE UPPER ACCELERATOR
PEDAL ASSEMBLY (WP 0396 00). If adjustment only is required, do the following steps.
1.
Remove upper accelerator pedal (WP 0396 00).
2.
Loosen two locknuts (1). Turn two set screws (2) in detent block (3) to right to increase spring pressure on plunger
(4), or to left to decrease pressure. Use scale to test for 35 to 40 pounds (16 to 18 kg) force required to push plunger
(4) through detent.
3.
Install upper accelerator pedal (WP 0396 00).
4.
Check operation of accelerator controls and transmission shift points. See CHECK OPERATION Steps 1 - 10.
CHECK OPERATION
WARNING
If you work on a carrier that has been running, you could be burned. All tasks begin with a
cooled down carrier. Allow carrier to cool or use care if you work on a hot carrier.
1.
Install power plant rear access panel (WP 0431 00 or WP 0433 00).
2.
Install driver’s power plant access panel (WP 0430 00).
3.
Close power plant front access door and raise trim vane (see your -10).
4.
Raise and lock ramp (see your -10).
5.
Operate carrier until engine and transmission are at normal operating temperatures (see your -10).
6.
With transmission range selector in 1 - 3 or 2 - 3 range and foot pedal held at full throttle position (detent plunger
contacting detent screw but not compressing detent plunger), upshift from second lockup to third converter should
occur at engine speed of 2640 to 2800 RPM.
7.
If engine speed is not within specified range, park carrier and stop engine.
