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.
3.
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.
4.
Tighten the vent screw (1) to a torque of 20 N·m
(15 lb ft)
5.
Energize the stop solenoid on the fuel injection
pump. Operate the priming lever of the fuel priming
pump several times.
6.
Crank the engine with the throttle lever in the
CLOSED position until the engine starts.
7.
Start the engine and run the engine at idle for 1
minute.
NOTICE
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.
8.
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.
9.
Check for leaks in the fuel system.
Type 2 Fuel Filters

Typical example
1.
Loosen the vent plug (1) on the primary fuel filter
base.
2.
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.
3.
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.
4.
Tighten the vent plug (1).
5.
Energize the stop solenoid on the fuel injection
pump. Operate the priming lever of the fuel priming
pump several times.
6.
Crank the engine with the throttle lever in the
CLOSED position until the engine starts.
7.
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
