Abnonnally high readings
on
all cylinders indicates heavy
carbon accumulations, a condition that might be
accompanied by high pressures and noise.
NOTE:
In
case
of
severe
vibrations and detonation
noise,
have
the
injectors checked and overhauled by
an
authorized fuel
injection service center.
Poor fuel
quality,
contaminates and
loss
of
positive fuel pressure
to
the
injection pump will result
in
injector faults.
When re-installing the glow plugs use anti-seize compound.

SPEED
(PROPULSION
ENGINE)
1. Warm the engine to
nonnal
operating temperature.
2.
Stick a piece
of
suitable reflecting tape on the crankshaft
pulley.
3. Idle the engine.
4.
Use the light
of
a photoelectric strobe type tachometer on
the reflecting tape and compare with the readings
on
the
electric tachometer.
Nonnal

speed
650

950
rpm
NOTE:
The
idle speed may vary according
to
the
transmission and
propeller.
5.
To
adjust the engine idle speed, loosen the lock nut
of
the
idle adjustment bolt and turn the bolt clockwise to
increase idle speed and counterclockwise to reduce.
NOTE:
Should
the
engine
rpm
be
in
question,
verify
the
tachometer
readings
as shown at
the
instrument panel.

ADJUSTMENT
(GENERATOR)
NOTE:
Speed adjustment
of
the
generator (hertz)
is
controlled
by
the
electronic governor
see
ELECTRONIC
GOVERNOR
for speed and gain adjustments.
Early
Models
Without
Electronic
Governing
Engine speed is maintained by the governor mechanism
inside the fuel injection pump (61.5 -
62.0 hertz
at
no-load
and 58.5 -
59.0 hertz
at
full rated generator output). Engine
no-load speed is adjusted by positioning the throttle lever
against the adjustable throttle stop screw, lock wiring
it
at
that position, and tensioning the throttle stop screw against
the throttle lever and securing
it
with its lock nut.
When servicing the injection pump, the service shop must
be
advised
if
the pump is to
be
used in a generator application.
The service shop will have to remove and replace the gover-
nor spring with a propulsion spring.
Once the pump is set to
propulsion specifications, the generator spring is reinstalled
in
the-injection pump and the
pump
remounted
on
the
engine. The throttle is then set for the proper engine no-load
speed
(hertz).
For disassembly, inspection, reassembly and internal
adjustments
of
the injection pump,
it
is recommended the
pump be taken to a qualified injection service shop
authorized to service Diesel KiKi injection equipment.

SOLENOID·
PROPULSION/GENERATOR
This solenoid is installed
on
the top rear
of
the injection
pump and is activated by
12
VDC
electrical current.
NOTE:
To
service generator applications, refer
to
the'
GENERATOR
section
of
this
manual.
Troubleshooting
1. The solenoid does not operate when the keys witch is
turned
"ON'. (Preheat depressed)
a.
Are the engine batteries turned "ON'?
b. Is the
20
amp circuit breaker set?
c. Is
12
VDC
present at the solenoid
connection?
2. The solenoid does not stop the engine
when the keyswitch is switched
"OFF'.
(Stop switch depressed)
a. Check to see
if
12
VDC
is still present
at the solenoid electrical lead with the
key off.
(Stop switch depressed)
b. Remove solenoid from injection
pump and ensure plunger and spring
in the solenoid are not sticking.
