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 and other foreign matter.
replacing Fuel Filter
Replace the fuel filter cartridge with a new one every
500 hours.
Loosen the drain plug at the lower top of the fuel filter.
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.
Refer to the Cummins engine manual for details.
CHeCK oil level
Check the crankcase oil level prior to each use, or when
the fuel tank is filled. Insufficient oil may cause severe
damage to the engine. The oil level must be between the
two notches on the dipstick.
replacing oil Filter
1. Remove the old oil filter.
2. Apply a film of oil to the gasket on the new oil filter.
