MODEL IDENTIFICATION 

Engine Serial Number 

The engine number is stamped on the rear left hand side 
of the cylinder body. 

The engine number is stamped in the plate in front of the 
engine room as well. 

 

 

AIR CLEANER 

Element cleaning procedures will vary according to the 
condition of the element. 

 

Dust Fouled Element (Except wet type element)

Rotate the element with your hand while applying 
compressed air to the inside of the element. This will blow 
the dust free.

LUBRICATING SYSTEM 

Main Oil Filter (Cartridge Type Paper Element) 
Replacement Procedure 

1.  Drain the engine oil. 

2.  Retighten the drain plug. 

3.  Loosen the used oil filter by turning it counterclockwise 

with a filter wrench.

4.  Clean the oil cooler fitting face. This will allow the new 

oil filter to seat properly. 

5.  Apply a light coat of engine oil to the filter O-ring. 

6.  Turn in the new oil filter until the filter O-ring is fitted 

against the sealing face. 

7.  Use the filter wrench to turn in the filter an additional 

2/3 turns.  
Filter Wrench: 5-8840-0200-0 

8.  Check the engine oil level and replenish to the 

specified level if required.

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.

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.

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.

Draining Procedure 

The indicator light will come on when the water level in the 
water separator exceeds the specified level. 

Drain the water and foreign material from the water 
separator (inside chassis frame) with the following 
procedure. 

 

 

 

 

 

 

1.  Place the drain pan under the drain plug. 

2.  Loosen the drain plug and drain water. 

3.  After draining the water, tighten the drain plug. 

4.  Operate the priming pump on the fuel filter several 

times and check for fuel leakage. 

5.  Check the water separator indicator light. It should be 

off.

Air Bleeding 

1.  Operate the priming pump until strong resistance is 

felt. 

2.  Wait 1 minute, and operate the priming pump until 

strong resistance is felt. 

3.  Once more wait, and operate the priming pump until 

strong resistance is felt. 

4.  Turn the ignition switch to the "ON" position. Wait until 

the glow indicator lamp turns off. 

5.  Turn the ignition switch to the "START" position and 

crank the engine until it starts. 

6.  If the engine does not start, repeat Step 3 - 5. 

7.  Allow the engine to idle for 3 minutes to bleed air 

completely form the fuel system and check for fuel 
leakage. 

Note: 

Insufficient air bleeding may cause the Diagnostic 
Trouble Code (DTC) store or improper engine 
performance.
