FUEL INJECTION PUMP I FUEL LIFT PUMP
CHECKING CAM LIFT
1. Turn the crankshaft in the direction of normal engine
rotation and read the maximum value which the dial
indicator pointer on the measuring device shows. This
value is cam lift.
.
Amount of Cam Lin 0.08 in (2.2 mm)
2. After this check, remove the measuring device and install
the plug and sealing washer.
3. Reinstall the
0.032 inch thick timing washer in the injec-
tion pump.
BLEEDING THE INJECTION PUMP
1. The injector pump and injector high pressure lines will
have to be bled
of air after the lines have been reinstalled.
To bleed the injection pump, first loosen the return con-
nection (a). Then, by priming with the lever on the engine
mounted fuel filter, supply fuel to the injection pump to
remove the
air from the injection pump. Continue until
fuel clear
of air passes out of the loosened return connec-
tion.
2. Next, bleed the high pressure lines by loosening them at
their attachment to the fuel injectors. Loosen the attach-
ing nuts (one to two turns) on all four fuel lines. Tum the
key on and crank the engine with the starter until fuel
spurts by the loosened connections.
Stop cranking the
engine. Tighten the attaching nuts and start the engine in
the usual manner.

Troubleshooting
This pump operates during the start sequence when preheat is
pressed. Simulate a start and depress preheat, the pump
should produce a clicking sound indicating the pumping
piston in the pump is working.
If no clicking is heard, check
that 12 volts are present at the pump connection and the
pump is properly grounded.
1. Test the pump by connecting a battery and fuel line as
illustrated. Fuel delivery must be
0.5 pints (225 cc) or
more every fifteen seconds.
