Make sure you read and understand the
information in the Lubricant Specifications section
of this manual before you proceed with
maintenance of the crankcase lube oil system.
Check Oil Level
1. Check the oil level with the engine stopped. DO
NOT check the oil level with the engine running.
NOTE: Refer to the Refill Capacities chart and
Lubricant Specifications to show the proper
amount and quality of oil to be used at oil
change time, and to determine the correct level
on the dipstick for your application.
2. Maintain the oil level between the ADD (MIN) and
FULL (MAX) marks on the dipstick. Ensure that the
engine oil level is not above the FULL (MAX) mark
on the dipstick. DO NOT overfill to reach above or,
to top of FULL (MAX) mark on the dipstick.
NOTE: Operating your engine when the oil level is
above the FULL (MAX) mark could cause your
crankshaft to dip into the oil. If this happens,
the air bubbles created from the crankshaft
dipping into the oil will reduce the lubricating
characteristics of your oil and could result in
the loss of power.
If the dipstick does not have a FULL (MAX) mark, refer
to calibrating the oil level gauge by consulting your
Caterpillar dealer before operating the engine.
3. Remove the oil filler cap and add oil if necessary.
The minimum capacity (ADD oil mark) is 5.6 liter
(5.9 U.S. quart) for the 3054 engine. See Refill
Capacities and Lubricant Specifications for the size
of your engine crankcase and recommended oil to
NOTE: Remote mounted or auxiliary oil filters will
require additional oil than what the Refill
Capacities chart states. For all information
pertaining to auxiliary oil filters, refer to the
OEM filter manufacturer's instructions.
