CAP 4799786 - Caterpillar

Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.
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 Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
The oil drain for the tractor engine is located on the engine oil pan. A guard covers the oil pan.The oil filters are located on the right side of 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 the oil and the particles will recirculate in the engine lubrication system with the new oil.
Park the machine on a level surface and engage the parking brake. Stop the engine.
The crankcase drain valve is located under the left side of the tractor.

Remove oil filters (3) with a strap type wrench. See Operation and Maintenance Manual, "Oil Filter - Inspect". Discard the used oil filters properly.
Clean the filter housing base with a clean towel. Make sure that all of the old filter gasket is removed.
Apply a thin coat of engine oil to the sealing surface of the new filters.
Install the new filters by hand. When the gasket contacts the filter base, turn the filter by 270 degrees more. This will tighten the filter sufficiently.
Every new oil filter has marks which are for determining the rotation index. These marks are spaced at 90 degree increments. Use the rotation index marks as a guide for tightening the oil filter.
Clean oil filler cap (4). Remove oil filler cap. Fill the crankcase with new oil. See Operation and Maintenance Manual, "Capacities (Refill)". Clean the oil filler cap and install the oil filler cap.
Start the engine and allow the oil to warm. Check the engine for leaks. Check the filters for leaks.
Run the engine and check oil gauge (5) after the engine has been running for ten minutes. Maintain the oil between the marks on the "SAFE OPERATING RANGE" side of the oil gauge. If necessary, add oil.
Close the engine access door and stop the engine.
