ENGINE BREAK-IN PROCEDURE
ENGINE BREAK-IN PROCEDURE
Although your engine has experienced a minimum of one hour of
test operations at the factory to make sure accurate assembly pro-
cedures 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 50 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 scored, which is
caused by overloading the engine during the break-in period.
Your new engine requires approximately 50 hours of initial condi-
tioning operation to break-in each moving part in order to maxi-
mize the performance and service life of the engine. Perform this
conditioning carefully, keeping in mind the following:
1. Start and stop the engine according to the STARTINGISTOP-
PING PROCEDURE section. Run the engine at fast idle
while checking that all systems are functioning.
2. Allow the engine to warm up, preferably by running at fast
idle.
NOTE: Some unstable running may occur in a cold engine. This
condition should abate as normal operating temperature is
reached and the propeller load is applied
3. While using the vessel, run the engine at various engine
speeds for the first 25 hours. Avoid prolonged periods of
idling.
4. Avoid rapid acceleration, especially with a cold engine.
S. Use caution not to overload the engine. The presence of a
grey or black exhaust and the inability of the engine to reach
its full rated speed are signs of an overload.
6. During the second 25 hours, the engine may be operated at
varying engine speeds, with short runs at full rated rpm.
Avoid prolonged idling during this break-in period.
Break-In Check List
Monitor the following during the 50 hour break-in period:
o Check for fuel, engine oil and water leaks.
o Check for abnormal noise such as knocking, friction, vibration
and blow-back sounds.
o Confmn the exhaust smoke:
When the engine is cold - white smoke.
When the engine is warm - almost smokeless.
When the engine is overloaded - some black smoke and soot.
Also see the DAILY OPERATION CHECKllSTfor additional
items to check each day.
The MAINTENANCE SCHEDULE section gives the maintenance
procedures to follow after the 50 hour break-in period.
Transmission Break-In
See the HURTH HBW TRANSMISSION section of this manual for
break-in information on your transmission.
DAILY OPERATION
DAILY OPERATION
Start and stop the engine according to the instructions given in the
STARTINGISTOPPING PROCEDURE section. Also follow the
instructions given in the ENGINE BREAK-IN PROCEDURE sec-
tion during the first 50 hours of operation. Make sure all periodic
maintenance is performed according to the MAINTENANCE
SCHEDULE.
Daily Operation Check List
Follow this check list each day before starling your engine.
o Record the hourmeter reading in your log (engine hours
relate to the maintenance schedule).
o Visually inspect the engine for fuel, oil or water leaks.
o Check the oil level (dipstick).
o Check the transmission fluid level.
o Check your diesel fuel supply.
o Look for clean fuel in the fuel filter/water separator transparent
bowl.
o Check for loose wires at the alternator and make sure its
mounting is secure.
o Check the starting batteries (weekly).
o Check drive belt for wear and proper tension (weekly).
o Check the raw water pump to make sure its mounting is
secure.
After starting the engine, check the following:
o Check for abnormal noise such as knocking, vibration and
blowby sounds.
o Confmn exhaust smoke:
When the engine is cold - white smoke.
When the engine is warm - almost smokeless.
When the engine is overloaded - some black smoke and soot.
o Make sure the cooling water is discharging properly, outboard
from the exhaust outlet.
