The angle indicates the number of degrees that the front of
the engine is raised. A negative angle indicates the number of
degrees that the front of the engine is lowered.
Verifying the Calibration of the Oil
Level Gauge
Caterpillar recommends verifying the calibration of
the oil level gauge at the first oil change. Use the
following procedure to verify the “FULL” mark on
the oil level gauge:
Note: The vessel must be level in order to perform
this procedure.
1. Operate the engine until normal operating
temperature is achieved. Stop the engine.
Remove one of the drain plugs for the engine
crankcase. Allow the engine oil to drain.
2. Remove the used engine oil filter. Install the new
engine oil filter. Install the crankcase drain plug
and tighten the crankcase drain plug.
3. Add 25 L (26.5 qt) of the recommended oil grade
and weight of engine oil to the crankcase.
Note: The engine may be equipped with auxiliary
engine oil filters which require additional oil. Refer
to the OEM specifications.
NOTICE
To help prevent crankshaft or bearing damage, crank
engine to fill all filters before starting. Do not crank
engine for more than 30 seconds.
NOTICE
Do not crank the engine for more than 30 seconds.
Allow the starting motor to cool for two minutes before
cranking again.
Turbocharger (if equipped) damage can result, if the
engine rpm is not kept low until the engine oil light/
gauge verifies the oil pressure is sufficient.
4. Start the engine. Ensure that the lubrication
system and the new engine oil filter is filled.
Inspect the lubrication system for leaks.
5. Stop the engine and allow the engine oil to drain
into the engine crankcase for approximately ten
minutes.
6. Check the engine oil level. If necessary, use a
marking pen in order to correct the “FULL” mark
(X).

In addition to a good preventive maintenance
program, Caterpillar recommends using S·O·S oil
analysis at regularly scheduled intervals in order
to monitor the condition of the engine and the
maintenance requirements of the engine.
Obtain the Sample and the Analysis
Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.
Before you take the oil sample, complete the Label,
PEEP5031 for identification of the sample. In order
to help obtain the most accurate analysis, provide
the following information:
