Type 1 Fuel Filters
Illustration 1 g02791865
Typical example
Loosen the vent screw (1) on the secondary fuel filter base.
Operate the priming lever of the fuel priming pump to eliminate any air between the fuel priming pump and the fuel filters. Note: The fuel priming pump is mechanically operated by the camshaft. If the lobe of the camshaft is acting upon the arm of the fuel priming pump, the ability to hand prime the fuel system will be reduced. If the resistance on the priming lever is low, rotate the crankshaft in order to move the camshaft lobe off the fuel priming pump arm.
Operate priming lever of the fuel priming pump by hand. Check that there is correct resistance on the fuel priming pump. Operate the fuel priming pump until fuel, free of air, comes from the vent screw.
Tighten the vent screw (1) to a torque of 20 N m (15 lb ft)
Energize the stop solenoid on the fuel injection pump. Operate the priming lever of the fuel priming pump several times.
Crank the engine with the throttle lever in the CLOSED position until the engine starts.
Start the engine and run the engine at idle for 1 minute.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
Cycle the throttle lever from the low idle position to the high idle position three times. The cycle time for the throttle lever is one second to 6 seconds for one complete cycle. Note: To purge air from the fuel injection pump on engines with a fixed throttle, the engine should be run at full load for 30 seconds. The load should then be decreased until the engine is at high idle. This should be repeated three times. This will assist in removing trapped air from the fuel injection pump.
Check for leaks in the fuel system. Type 2 Fuel Filters
