ENGINE MAINTENANCE
Refer to the MAINTENANCE SCHEDULE for a complete
listing of required maintenance and the frequency at
which it should be performed. Some procedures may
be performed by the owner/operator while others should
be performed by an authorized PCM Engines Dealer.
Before performing any maintenance or repair procedure
not covered in this manual, it is strongly recommended
that a PCM Engines repair manual be purchased and
read thoroughly.
CHECKING FLUID LEVELS
Engine Crankcase Oil
CAUTION
Do not overfi ll engine crankcase with oil, as excess
oil will be splashed by reciprocating engine parts onto
the cylinder walls in greater quantity than the rings
can control. The oil, subsequently, will be drawn into
the combustion chamber and burned. Continuous
operation under these conditions can cause carbon
to form on combustion chamber surfaces, which will
adversely affect engine performance and may lead
to premature engine failure. Splashing or agitation
of oil also may cause it to become aerated, which
will affect the oil pressure, and may result in internal
engine damage from lack of lubrication.
1. Stop the engine if running. Allow approximately 5
minutes for the oil to drain back into the oil pan.
2. Remove the dipstick, wipe it clean, and reinstall it
fully into the dipstick tube.
3. Remove the dipstick and observe the oil level.
The oil level must be between the “FULL” and
“ADD” marks. If the oil level is below the “ADD”
mark, add specifi ed oil to bring the level up to,
but not over, the “FULL” mark on the dipstick.
(Figure 11-1).
WARNING
The machinery space must be closed anytime the
engine is running to prevent injury to you or others
on board. Never operate the engine with the engine
machinery space open while someone is in the
machinery space, either closed or open. Never open
the machinery space unless the engine is shut
off and the engines rotating parts are stationary.
Rotating machinery can cause injury and even death
if an accident should occur. Extreme care must be
exercised if a problem exists that requires operation
of the engine with the machinery space open.
IT
IS RECOMMENDED THAT UNCOVERED ENGINE
OPERATION BE ATTEMPTED BY TRAINED AND
QUALIFIED SERVICE PERSONNEL ONLY.
