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
The vehicle must be parked on a level surface to perform this maintenance procedure.
1. Check the oil level with the engine stopped.Ensure that the engine when the oil level is not above the FULL RANGE zone on the dipstick. 2. Maintain the oil level between the ADD and FULL marks in the FULL RANGE zone on the ENGINE STOPPED side of the dipstick. Do not fill the crankcase above the FULL RANGE zone. Operating your engine when the oil level is above the FULL RANGE zone 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 also result in the loss of power.If the dipstick does not have a FULL mark in the FULL RANGE zone, refer to Dipstick Calibration in this manual or consult your Caterpillar dealer before changing oil and operating the engine. 3. Remove the oil filler cap and add oil if necessary. See Refill Capacities and Lubricant Specifications for the size of your engine crankcase and recommended oil to use. Remote mounted filter or auxiliary filters require additional oil than what the Refill Capacities chart states. For all information pertaining to auxiliary oil filters, refer to the truck OEM or filter manufacturer's instructions.
