Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose of all fluids according to local regulations and mandates. |
Park the machine on a level surface and engage the parking brake. Lower the dump body and stop the engine.
Note: Drain the crankcase while the oil is warm. This allows waste particles that are suspended in the oil to drain. As the oil cools, the waste particles will settle to the bottom of the crankcase. The particles will not be removed by draining oil and the particles will recirculate in the engine lubrication system with the new oil.
- Open the hood.
- Remove the crankcase drain plug. Allow the oil to drain into a suitable container.

- Clean the oil filter base. Make sure that all of the old oil filter gasket is removed.
- Apply a thin coat of engine oil to the gasket of the new oil filter.
- Install the new oil filter by hand. When the gasket contacts the oil filter base, turn the oil filter by 270° more. This will tighten the oil filter sufficiently.
Each new oil filter has rotation index marks that are spaced at 90 degree increments. Use the rotation index marks as a guide for tightening the oil filter.
- Remove oil filler cap (2). Fill the crankcase with new oil. Check the "SAFE STARTING RANGE WITH ENGINE STOPPED AND OIL COLD" side of dipstick (1) while the engine is stopped and the oil is cold. Maintain the oil level within the shaded area of the dipstick. Clean the oil filler cap and install the oil filler cap.
Refer to the Operation and Maintenance Manual, "Lubricant Viscosities and Refill Capacities".

- Start the engine and allow the oil to warm. Check the engine for leaks.
- After the engine has been running for ten minutes and the oil is warm, check the "ENGINE RUNNING AT LOW IDLE WITH WARM OIL" side of dipstick (1). Maintain the oil level between the "ADD" mark and the "FULL" mark. If necessary, add oil.
- Close the hood and stop the engine.
