3116 and 3126 Marine Engines Caterpillar

The engine is shipped with an engine oil level gauge that is not marked. The engine oil level gauge is not marked because the angle of installation can be different for each engine. The angle of installation will affect the "ADD" mark (Y) and the "FULL" mark (X) that is engraved on the engine oil level gauge.

The engine oil level gauge must be calibrated after the engine is installed in the vessel. Table 1 and Table 2 list the corresponding "ADD" mark, "FULL" mark and the angle of installation. Use a marking pen in order to engrave "ADD" mark (Y) and "FULL" mark (X) on the engine oil level gauge according to the information in Table 1 or Table 2.

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.

   Show/hide table

   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).
