ENGINE LUBRICATION SYSTEM
Continental industrial diesel engines have full pressure
lubrication to all main, connecting rod, and camshaft
bearings-as well as rocker arms and timing gears.
Tappets are lubricated by overhead oil return.
OIL PUMP
On all engines, a large capacity gerotor-type oil pump is
driven off the crankshaft and protected by a screened
inlet.
A bypass valve maintains suitable oil pressure from idle
to maximum speed automatically. Higher oil pressure
may be experienced during cold starts.
Refer to Section 2 for complete oil pressure figures.
If the oil pressure s erratic or falls
below these limits, atop the engine
IMMEDIATELY and find the cause of
the trouble or damage to equipment
could result Refer to troubleshooting
section for this Information.
A full flow oil filter is provided to remove dirt and foreign
elements from the oil. The removal of grit, sludge, and
foreign particles causes filter elements to clog and
become ineffective unless they are normally replaced
every 100 hours, or more often if conditions require.
OIL CHANGE FREQUENCY
Engine oil does not Swear out"-however, the lubricating
oil
in
internal-combustion
engines
becomes
contaminated from the by-products of combustion: dirt,
water, and unburned fuel entering the crankcase, and
the detergents holding the carbon particles in suspension
in the crankcase.
NOTE
On engines equipped with remote oil
filters,
always
fill
the
oil
filters
element with motor oil
prior
to
Installation. Failure to do so may
result In engine damage due to
momentary oil starvation at start up.
ON Filter
The schedule for changing oil is directly dependent upon
the operational environment: an extremely clean
operation could go 100 hours while a dirty operation
(foundry or cement factory) could be 50 hours or less
(See suggested oil and filter change intervals).
