Benerator Break-In Procedure; Daily Routine - Westerbeke 29.0 EGED 60Hz Operator's Manual

GENERATOR BREAK-IN PROCEDURE
DESCRIPTION
Although your engine has experienced a minimum of one
hour of test operations at the factory to make sure accurate
assembly procedures were followed and that the engine
operated properly, a break-in time is required. The service
life of your engine is dependent upon how the engine is
operated and serviced during its initial hours of use.
Breaking in a new engine basically involves seating the
piston rings to the cylinder walls. Excessive oil consumption
and smoky operation indicate that the cylinder walls are
glazed or scored, which is caused by overloading the engine
during the break-in period.
Your new engine requires approximately
50
hours of initial
conditioning operation to break in each moving pari in order
to maximize
the
perfonnance and service life of the engine.
Perform this conditioning carefully, keeping in mind the
following:
Start the engine according to the STARTING PROCEDURE
section. Run the engine while checking
that
all systems (raw
water pump, oil pressure, battery charging) are functioning.
AFTER START·UP
Once the generator has been
started,
check for proper
operation and then encourage a fast warm-up. Run the
generator between 20% and 60% of full-load for the first
tO
hours.
After the
first
10
hours of the generator's operation, the load
can be increased to the full-load rated output, then
periodically vary the load.
Avoid overload
at
all times.
An
overload is signaled by
smoky exhaust with reduced output voltage and frequency.
Monitor the current being drawn from the generator and keep
it within the generator's rating. Since the generator operates
at 1800 rpm to produce 60 hertz (or at 1500 rpm to produce
50
Hertz), control of the generator's break-in is governed by
the current drawn from the generator.
NOTE: Be aware of motor starting loads
and
the high current
draw required for starting motors. This starting amperage
draw can be 3 to 5 times normal running amperage. See
GENERATOR INFORMATION in this manual.
GENERATOR' ADJUSTMENTS
Once the generator has been placed in operation and during
the initial 50 hours ofbreak.-in operation or after, the no-load
AC voltage output may need adjustment using the voltage
pod on the AVR found in the generators control box. Review
the GENERATOR section of this manual for infonnation.
THE DAILY ROUTINE
CHECK LIST
Follow this check list each day before starting your generator.
• Check that all generator circuit breakers (power panel) are
in the off position before starting.
• Record the hounnete:r reading in your log (engine hours
relate to the maintenance schedule).
Any deficiency or problems
in
the following items must
be corrected before
start-up.
• Visually inspect the engine for fuel, oil, or water leaks.
• Check the oil level (dipstick).
• Check the coolantlevel in
the
coolant recovery tank.
• Check your fuel supply.
• Check the starting batteries (weekly).
• Check drive belts for wear and proper tension (weekly).
CHECK WITH ENGINE RUNNING
• Check for abnormal noise such as knocking, vibration and
blow-back sounds. ·
• Confirm exhaust smoke:
When the engine is cold - white smoke.
When the engine is warm- almost smokeless.
When the engine is overloaded - some black smoke.
NOTE: Some unstable running
may
occur in a cold engine.
This condition should abate as normal operating temperature
is reached
and
loads are applied.
CAUTION:
Do not operate the generator for long
periods of time without a load being placed on the
=generator.
STOPPING THE GENERATOR
Remove the AC amperage loads from the generator one at a
time. Allow the generator to run for 3-5 minutes to stabilize
the operating temperatures. Then depress the STOP switch
and ·hold. depressed until the generator comes to a complete
STOP.
