Oil Pressure; Glow Plugs - Westerbeke 7.6 kw EDT Operator's Manual

ENGINE ADJUSTMENTS
NOTE: WESTERBEKE recommends that the following engine adjust-
ments be peiformed by a competent engine mechanic. The information
_ below is provided to
ass~st

OIL PRESSURE
The engine's oil pressure,is constantly monitored by the control
pane\. The red light will illuminate and the generator will
shutdown if the oil pressure fall below 5 psi. Do not restart the
generator without checking the oil and finding the problem.-

NOTE:
A newly started, cold engine can have an oil pressure
reading upwards of 60 psi. A warmed engine can have an oil
pressure reading as low as 35 psi. These readings
will
vary
depending upon the temperature of the engine and the load
placed on the generator. -
LOW OIL PRESSURE
The specified safe minimum oil pressure is 4.3 - 1.4 psi(0.3 -
0.1 kg/cm". An oil pressure of 5 PSI will shut the engine
down. A gradual loss of oil pressure usually indicates worn
bearings. For additional information on low oil pressure read-
ings, see the ENGINE TROUBLESHOOTING chart.
TESTING OIL PRESSURE
To test oil pressure, -remove the oil gallery "T" plug and
install a mechanical oil pressure gauge in its place. After
warming up the engine, read the oil pressure gauge.

TESTING GLOW PLUGS
To inspect the plug, remove the electrical terminal connec-
tions, then unscrew or unclamp each plug from
the
cyIin4er
head. Thoroughly clean each plug's tip and threads with a
soft brush and cleaning solution to remove all the carbon and
oil deposits. While cleaning, examine the tip for wear and
burn erosion; if it has eroded too much, replace the plug.
An accurate way to test glow plugs is with an ohmmeter.
Touch one prod to the glow plug's wire connection, and the
other to the body of the glow plug, as shown. A good glow
plug will have a 0.4 - 0.6 ohm resistance. This method can be
used with the plug in or out of the engine. You can also use
an anuneter to test the power drain (5 - 6 amps per plug).
A
WARNING:
These glow plugs will become very hot
to the touch. Be careful not to burn your fil1gers when
testing the plugs.

the plugs in the engine and test them again. The
plugs should get very hot (at the terminal end) within 7 to 15
seconds. If the plugs don't heat up quickly, check for a short
circuit. When reinstalling the glow plugs, use anti-seize com-
pound on the threads.
