ADJUSTMENTS
NOTE:
WESTERBEKE
recommends
that
the
following
engine
adjust-
ments
be
performed by a competent
engine
mechanic.
The
information
below
is
provided
to
assist
the
mechanic.
Injection
Pump
Timing
Adjustment
(Spill
Timing)
If
your engine's fuel injection timing
is
not properly adjusted,
the engine
will not operate
properly,
and
may
be
difficult to
start. Have
the
injection
pump
delivery rate checked
by
a
well-established fuel injection
shop.
Adjust
the
injection
as
follows:
NOTE:
The
injection
PTm1P
fuel
rack
needs
to
be
in
the
full
fuel delivery position
when
performing
this
spill
timing.
To
do
this,
unscrew
the fuel shut off solenoid
and
remove
the
side cover
to
expose
the
injection
pump
fuel
rack.
Manually
move
the
fuel rack
to
thefullfuel
delivery
position
(move
fully
to
the
left)
secure
it
in
this
position
then
proceed.
1. Remove
the
high pressure
fuel
line
from
between the
No.
1 injector and the
No.
1
fuel
delivery
valve
holder.
2. Remove
the
No.
1 fuel delivery
valve
holder over
"0"
ring
and
remove the delivery
valve
spring
beneath
the
holder.
3. Reinstall only the delivery valve holder
and
reattach the
high pressure fuel line to the delivery
holder.
Attach it
so
that the
end
that would connect
to
the
fuel
injector
is
pointing
away
from the engine
fuel
will
flow
from
this
line during
the timing
check.
Rotate
the engine's crankshaft
in
its
normal
direction of
rotation
to
position piston
the
No.
1 at
the
beginning of
its
compression stroke.
Move
the
throttle levet
to
its
full
open
position
and
operate
the
electric
lift
pump.
Slowly rotate
the
crankshaft clockwise
(as
viewed
from
the
front),
catching
the
fuel
from
the
No.1
fuel
line,
until
the
instant
the
fuel
completely
stops
flowing
(no
drips).
At
this
instant,
the
11
0
BIDe
timing
mark
on
the
crankshaft pulley should be directly aligned
with
the
timing
indicator on the
front
of
the
gear case ±
.5
degrees.
If
the
specified injection timing
(11
0
BIDC) cannot be
attained,
adjust
the
timing
by
increasing or decreasing
the
thickness
of shim material under
the
injection pump's
mounting
flange
to
change
the
injection timing point.
Changing
the
shim thickness by 0.004 inch
(O.Olmm)
changes
the
injection timing
by
approximately
one
degree.
To
advance
the
timing, decrease
the
shim
thickness,
as
required.
To
retard
the
timing,
increase
the
shim
thickness,
as
required.
Refer
to
your Generator's
Parts
List for
shim
part
numbers.
