DRIVE
BELT
ADJUSTMENT
Proper inspection, service
and
maintenance of
the
drive
belts
is
important for
the
efficient operation of your engine
(see
Drive Belts under MAINTENANCE SCHEDULE).
Drive
belts must
be
properly tensioned. Loose
drive
belts will
not provide proper alternator charging
and
will eventually
damage
the
alternator.
Drive
belts that are too tight will pull
the
alternator out of alignment and/or cause
the
alternator
to
wear out
prematurely.
Excessive
drive
belt tension can also
cause rapid wear of
the
belt
and
reduce
the
service life of
the
fresh water pumps bearing. A slack belt or
the
presence of oil
on
the
belt can cause belt slipping, resulting in high operating
temperatures.
The
drive
belt
is
properly adjusted if the belt can be deflected
no
less
than
3/8
inch
(lOmm)
and
no
more than
1/2
inch
(12mm)
as
the
belt
is
depressed with
the
thumb
at
the
mid-
point between
the
two
pulleys
on
the longest span of
the
belt.
A spare belt or belts should always be carried
on
board.
A
WARNING:
Never
anempt
to
check
or
adjust
the
drive
belt's
tension
while
the
engine
is
in
operation.
Adjusting
Belt
Tension
1. Loosen
the
alternator adjusting strap bolt
and
the base
mounting bolt.
2.
With
the
belt
loose,
inspect
for
wear,
cracks
and
frayed
edges.
3.
Pivot
the
alternator
on
the
base mounting bolt
to
the
left
or right
as
required,
to
loosen or tighten.
4.
Tighten
the
base
mounting
bolt
and
the
adjusting
strap
bolt.
5.
Run
the
engine for about 5 minutes, then shut
down
and
recheck the belt tensions.
ENGINE
SPEED/ENGINE
SHUTDOWN
Generator frequency (hertz)
is
a direct result of engine speed.
The engine speed throttle adjusting screws
have
been pre-set
at
the
factory.
A
fuel
shut off solenoid, located
at
the
injection
pump,
shuts
the
generator
down
when
tl1e
control panel toggle switch
is
depressed. This solenoid
is
pre-set
at
the
factory.

ELECTRONIC
GOVERNOR
(OPTIONAL)ยท
The Electronic Governor regulates
the
engine speed
by
sensing
the
engine's RPM
with
a magnetic pick
up
at
the
flywheel.
The governor's controller continuously
monitors
the
engines speed
and
if there
is
any
discrepancy,
the
controller signals
the
actuator
and
the actuator adjusts
the
engine
to
the
desired speed electronically.
ACTUATOR
Actuator
The following instructions are
for
adjusting
or
replacing
the actuator.
1.
Shut-off the
DC
power
to
the generator.
2.
Disconnect
the
actuator
wires
from
the
wiring
harness.
3.
Measure
the
distance between the actuator
and
the
engine
mounting surface
as
shown.

4.
Back-off
the
1 7/16" jam nut
and
unscrew
the
actuator.
5.
Apply
a small amount of teflon sealant
to
the
replacement
actuator
and
screw
the
actuator into
the
engine's
mounting
boss.
Maintain
the
same distance between
the
actuator and the engine mounting surface
as
previously
measured Secure the actuator's position
with
the
jam
nut.
(The
standard distance
is
13/16"
to
7/8").
6.
Reconnect
the
actuator wires
and
test
the
unit.
