FUEL SYSTEM
Fuel Filter Replacement Procedure
1. Remove the fuel filter by turning it counterclockwise
with a filter wrench.
Filter Wrench: 5-8840-0253-0 (J-22700)
Note:
Be careful not to spill the fuel in the filter cartridge.






RTW46ASH000501








2. Clean the fuel filter cartridge fitting faces.
This will allow the new fuel filter to seat properly
3. Apply a light coat of engine oil to the O-ring.
4. Turn in the fuel filter until the sealing face comes in
contact with the O-ring.
5. Turn in the fuel filter an additional 2/3 of a turn with a
filter wrench.
Filter Wrench : 5-8840-0253-0 (J-22700)





6. Operate the priming pump until the air discharged
completely from fuel system.
7. Start the engine and check for fuel leakage.
Note:
The use of an ISUZU genuine fuel filter is strongly
recommended.

If the injection timing is outside the specified range,
continue with the following steps.


10. Loosen the injection pump fixing nuts and bracket
bolts.
11. Adjust the injection pump setting angle.

A: Move the injection pump toward the engine.
R: Move the injection pump away from the engine.

ENGINE CONTROL (4JA1T(L) only)
Idling Speed Adjustment
1. Set the vehicle parking brake and chock the drive
wheels.
2. Place the transmission in neutral.
3. Start the engine and allow it to idle until the coolant
temperature reaches 70 - 80C (158 - 176F).


4. Disconnect the engine control cable from the control
lever.
5. Set a tachometer to the engine.
6. Check the engine idling speed.
If the engine idling speed is outside the specified
range, it must be adjusted.
Engine Idling Speed : 730  25 rpm


Idling Speed Adjustment
1. Loosen the idling set screw lock nut
on the injection
pump idling set bolt.
2. Adjust the idling speed to the specified range by
turning the idling set bolt
.
3. Lock the engine set nut

with the idling set bolt lock
nut.
4. Check that the idling control cable is tight (free of
slack). If required, remove the slack from the cable.

19. Crankshaft Timing Gear
Use the crankshaft timing gear installer (1) to install the
crankshaft timing gear (2).
The crankshaft timing gear setting mark must be facing
outward.
Crankshaft Timing Gear Installer: 9-8522-0020-0


















20. Idler Gear Shaft
21. Idler Gear "A"
1. Turn the crankshaft clockwise to set the DTC of the
No.1 piston.
2. Apply engine oil to the idler gear and the idler gear
shaft.
The idler gear shaft oil hole (A) must be facing up.
3. Position the idler gear setting marks so that they are
facing the front of the engine.

BRUSH AND BRUSH HOLDER
1. Use a vernier caliper to measure the brush length (four
brushes).
Replace the brushes as a set if one or more of the
brush lengths is less than the specified limit.
Brush Length mm (in)
Standard Limit

2. Use a circuit tester to check the brush holder
insulation.
Touch one probe to the holder plate and the other
probe to the positive brush holder.
There should be no continuity.





3. Inspect the brushes for excessive wear.
If the negative brushes have excessive wear, the
entire brush holder assembly must be replaced.
If the positive brushes have excessive wear, the entire
yoke must be replaced.

OVERRUNNING CLUTCH
1. Inspect the overrunning clutch gear teeth for
excessive wear and damage.
Replace the overrunning clutch if necessary.
2. Rotate the pinion clockwise.
It should turn smoothly.
3. Try to rotate the pinion in the opposite direction.
The pinion should lock.
