ACCELERATOR CONTROL CABLE

Component

Removal

1. Adjust Nut

• Loosen the adjust nut on the cable bracket mount-

ed on the inlet manifold.

2. Accelerator Control Wire (Injection Pump Side)

• Remove the control wire from injection pump con-

trol lever.

3. Accelerator Control Wire (Accelerator Pedal Side)

• Remove the accelerator control wire from acceler-

ator pedal.

4. Accelerator Control Cable

• Remove the cable clip from intake manifold duct.
• Remove the cable clip from chassis frame.
• Pull out the wire to the chassis side through the

grommet hole of the floor board, and remove the
control cable.

Inspection

Check the following items, and replace the control cable
if any abnormality is found.

• The control cable should move smoothly.
• The control cable should not be bent or kinked.
• The control cable should be free of damage and

corrosion.

Installation

1. Accelerator Control Cable

• Take care that the core wire of the cable does not

get damaged or kinked.

• Pull the cable through the grommet hole from un-

der the floor.

• Set the groove of the grommet securely into the

floor panel.

• Lower the cab.

2. Accelerator Control Wire (Accelerator pedal side)

• Connect the accelerator control wire to the acceler-

ator pedal.

• Check to see if the idling control knob is fully turned

to the left.

• Tilt up the cab.

3. Accelerator Control Wire (Injection pump side)

• Install the tip end of the wire to the engine control

lever.

4. Lock Bolt

• With the accelerator control lever attached to the

stopper bolt, pull the cable lightly toward the front
of the axis and fasten the cable bracket with the
lock bolt.

• Check to see if the injection pump lever is at the

idle position (with the lever in touch with the stop-
per bolt).

• Connect the battery ground cable.
• Lower the cab.
• Check to see if the accelerator pedal play is in the

range of 5 — 10 mm above the pedal pad.

• Press down on the accelerator pedal fully, and

check to see if the engine rotates at the maximum
speed with the linkage in the smooth operation.

• In the operating range of the accelerator pedal,

check to see if the accelerator pedal and the injec-
tion pump lever return without fail to their original
positions respectively.
