Reassembly
Assemble injection nozzles in the reverse order
of
disassembly.
Be
sure to assemble nozzle assembly in kero-
sene.
\\hen using
new
needle vavles, remove sealing cover (syn-
thetic resin) from the valves and wash them in kerosene
to remove rust and corrosion inhibitor sprayed over them
by sliding the
valves
in the nozzles immersed in kerosene.
[NOTE]
If
the needle
valve
and nozzle proper have to be
replaced,
be
sure to wash the replacement parts
in the pool
of
kerosine after removing their
protective
fIlm
of
plastic: wash
off
the rust-
preven
tive
oil from the nozzle proper by
stroking the needle
valve
back and forth in the
needle
valve
stem bore.
6. Fuel feed pump
The camshaft in the bottom section
of
the injection
pump has an eccentric cam besides the cams for actu-
ating the individual pump elements.
By
this eccentric
cam, the pumping plunger
of
the feed pump
is
actuated
to draw fuel through the inlet strainer and forward it
to
the injection pump.
A means
of
manually priming the fuel circuit
is
provided
in this pump.
It
consists
of
a plunger and a knob.
Pushing the knob in rapid repetition sends the fuel
forward. The fuel circuit from the feed pump through
the fuel ftlter to the injection pump can be primed in
this manner. This feature is utilized also in bleeding air
out
of
the fuel circuit.
