MAINTENANCE

If the engine is operating in very dusty or dry grass

conditions, a clogged air cleaner will result. This can lead to

a loss of power, excessive carbon buildup in the combustion

chamber and high fuel consumption. Change air cleaner

more frequently if these conditions exists.

FUEL ADDITION

Add diesel fuel (the grade may vary according to season

and locations).

Removing Water from the Fuel Tank

After prolonged use, water and other impurities accumulate

in the bottom of the tank. Occasionally inspect the fuel

tank for water contamination and drain the contents if

required.

During cold weather, the more empty volume inside the

tank, the easier it is for water to condense. This can be

reduced by keeping the tank full with diesel fuel.

Cleaning Inside the Fuel Tank

Drain the fuel inside the fuel tank completely. Using a spray

washer (Figure 59) wash out any deposits or debris that

have accumulated inside the fuel tank.

Figure 59. Fuel Tank Cleaning

FUEL TANK INSPECTION

In addition to cleaning the fuel tank, the following

components should be inspected for wear:

 Rubber Suspension — look for signs of wear or

deformity due to contact with oil. Replace the rubber

suspension if necessary.

 Fuel Hoses — inspect nylon and rubber hoses for signs

of wear, deterioration and hardening.

 Fuel Tank Lining — inspect the fuel tank lining for signs

of excessive amounts of oil or other foreign matter.

Replacing Fuel Filter

 Replace the fuel ﬁ lter cartridge with new one every 500

hours or so.

 Loosen the drain plug at the lower top of the fuel ﬁ lter.

Drain the fuel in the fuel body together with the mixed

water. DO NOT spill the fuel during disassembly.

 Vent any air

AIR REMOVAL

If air enters the fuel injection system of a diesel engine,

starting becomes impossible. After running out of fuel,

or after disassembling the fuel system, bleed the system

according to the following procedure. See the ISUZU

Engine Manual for details.
