ENGINE ADJUSTMENTS ·
DRIVE BELT ADJUSTMENT
For your safety, WESTERBEKE generator models come
equipped with belt guards that cover the belt(s) on the front
of the engine. ("Out of Sight-Out of Mind". The belt guard is
NOT installed for that purpose). Operators are advised that
proper inspection, service and maintenance is required.
The drive belts must be properly tensioned. Excessive drive
belt tension can cause rapid wear of the belt and reduce the ·
service life of the fresh water pump's bearing. A slack belt or
the presence of oil on the belt can cause belt slipping,
resulting in high operating temperatures.
The generator has one drive belt that drives the DC alternator.
The tension adjustment procedure for the belt is as follows:
A
WARNING:
Never attempt to check or adjust the
drive belt's tension while the engine is in operation.
1. Remove the belt guard.
2. Loosen the alternator adjusting strap bolt and the base
mounting bolt.
3. With the belt loose, inspect for wear, cracks, and frayed
edges.
4. Pivot the alternator on the base mounting bolt to the left or
right as required, to loosen or tighten.
5. The drive belt is properly adjusted if it can be deflected no
. less than 3/8 inch (10mm) and no more than 1/2 inch
(12mm) as the belt is depressed with the thumb at the
midpoint between the two pulleys on the longest span of
the belt.
6. Operate the generator for about 5 minutes then shut down
and recheck the belt tension.
7. Replace the belt guard.
FUEL INJECTORS
Fuel injectors should be removed for service/rebuild and
reinstalled by a competent mechanic. Information regarding
fuel injector removal/inspection/rebuild/testing is found in the
Service Manual for the models listed in thus manual.
An authorized Fuel Injection shop should be contacted when
fuel injection is required. Injector servicing at a Fuel
Injection shop is performed in a "clean room" environment
generally not fo1;1nd in your standard diesel service shop.
Authorized Fuel Injection Repair Shops can be located
through your area yellow pages.
NOTE: Clean the area around the base of the injector
prior to lifting it out of the cylinder head to help prevent
any rust or debris from falling down into the injector
hole. If the injector will not lift out easily and
is
held in
by carbon build up or the like, work the injector si9-e to
side with the aid of the l7mm deep socket wrench to free
it and then lift it out.

TROUBLESHOOTING WATER TEMPERATURE AND OIL PRESSURE GAUGES
If the gauge reading is other than what is normally indicated
by the gauge when the instrument panel is energized, the first
step is to check for 12 volts DC between the ignition (B+)
and the Negative (B-) terminals of the gauge.
Assuming that there is 12 volts as required, leave the
instrument panel energized( engine on( and perform the
following steps:
1. Disconnect the sender wire at the gauge and see if the
gauge reads zero, which is the normal reading for this
situation.
2. Remove the electrical connection at the sender on the
engine and ground it to the engine metal. The gauge
should register full scale, which is the normal reading for
this situation.
If both of the gauge tests are positive, the gauge is
undoubtedly OK and the problem lies either with the
conductor from the sender to the gauge or with the sender.
If either of the gauge tests are negative, the gauge is probably
defective and should be replaced.
Assuming the gauge is OK, check the conductor from the
sender to the sender terminal at the gauge for continuity.
Check that the engine block is connected to the ground.
Some starters have isolated ground terminals and if the
battery is connected to the starter (both plus and minus
terminals), the ground side will not necessarily be connected
to the block.
