Notes on fuel system
See on facing page a typical
explode~
view of a fuel system for a
two cylinder engine.
It is also illustrative of the self-bleeding
system used on the Westerbeke 3 KW marine generator set.
The Westerbeke self-bleeding
fuel
system is automatic in opera-
tion.
While it is unlikely that the operator will be forced to
service the system at sea, the possibility does exist.
Therefore,
it is recommended that the following parts be carried onboard.
Banjo washers #'s 11, 30, 31, 33, 34, 45
Injector seat washers #42
Lift pump filter and gaskets #'s 6, 7, 8
Fuel filter element and gaskets #'s 13, 14 ,15
I f
a
leak
should develop at
a
banjo or
washer
that cannot be
remedied by a simple tightening of the screw, renew the washers.
The engine can be started by taking the steps described on pages 8
and 9.
In cases where the engine cannot be started easily, loosen
two
injection nuts on
the
nozzle
side,
turn
the
speed control
lever
to "full open" position,
turn the starter motor and then
tighten the nuts firmly.

Cleaning fuel filter and replacing filter element
After the first 50 hours of operation, loosen the retainer ring
#16 and discard filter element #15.
Clean bowl #17 and re-install
new filter, using new gasket #13 and #14.
This same treatment is required of the filter element #6 in the
fuel lift pump.
Similarly,
replace new filter element #6 using
new gasket #7 and #8.
After the first 50 hour change, the change period may be increased
to 200 hours or once per season.

Fuel injection pump
The fuel injection pump is one of the most important components of
the diesel
engine
and
thus
it calls for
the ,utmost caution in
handling.
Furthermore,
the
fuel
injection
pump
has
been
thoroughly
shop-adjusted
and
should
never
be
readjusted
care-
lessly.
Such
adj ustment,
whenever
necessary,
should
be per formed
at an
authorized service station, as a precision pump tester and skills
are required.
To obtain long and satisfactory use of your injection pump:
Always use fuel which is free from impurities.
Clean and renew the fuel filter periodically.
Inspect water entrapment filter regularly.
