Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact the skin.
Do not drain the oil when the engine is cold. As the oil cools, suspended waste particles settle on the bottom of the oil pan. The waste particles are not removed with the draining cold oil. Drain the crankcase with the engine stopped. Drain the crankcase with the oil warm. This draining method allows the waste particles that are suspended in the oil to be drained properly.Failure to follow this recommended procedure will cause the waste particles to be recirculated through the engine lubrication system with the new oil.Drain the Engine Oil
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.
Remove the oil drain plug from the oil pan or use one of the following methods in order to drain the engine oil into a suitable container. Dispose of the used oil in accordance with local regulations.Drain Valve (If Equipped)

Drain valve for the engine oil
The oil drain valve may be connected to the used oil tank for the vessel. The drain valve may have a plug that is threaded into the end of the valve or the fittings on the valve. If there is a plug, remove the plug.
Open the drain valve and allow the oil to drain into a suitable container or the piping for used oil on the vessel. Dispose of the used oil in accordance with local regulations. Replace the Oil Filter
Caterpillar oil filters are built to Caterpillar specifications. Use of an oil filter not recommended by Caterpillar could result in severe engine damage to the engine bearings, crankshaft, etc., as a result of the larger waste particles from unfiltered oil entering the engine lubricating system. Only use oil filters recommended by Caterpillar.
Remove the oil filter with a 1U-8760 Chain Wrench.
Cut the oil filter open with a 175-7546 Oil Filter Cutter. Break apart the pleats and inspect the oil filter for metal debris. An excessive amount of metal debris in the oil filter may indicate early wear or a pending failure. Use a magnet to differentiate between the ferrous metals and the nonferrous metals that are found in the oil filter element. Ferrous metals may indicate wear on the steel and cast iron parts of the engine.Nonferrous metals may indicate wear on the aluminum parts, brass parts or bronze parts of the engine. Parts that may be affected include the following items: main bearings, rod bearings, turbocharger bearings and cylinder heads.Due to normal wear and friction, it is not uncommon to find small amounts of debris in the oil
