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.Dispose of all fluids according to local regulations and mandates.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Do not drain the engine lubricating oil when the engine is cold. As the engine lubricating oil cools, suspended waste particles settle on the bottom of the oil pan. The waste particles are not removed with draining cold oil. Drain the oil pan with the engine stopped. Drain the oil pan 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 Lubricating Oil
Note: Ensure that the vessel that will be used is large enough to collect the waste oil.After the engine has been run at the normal operating temperature, stop the engine. Use one of the following methods to drain the engine oil pan:
Illustration 1 g02131361
If the engine is equipped with a drain valve (2), turn the drain valve knob counterclockwise in order to drain the oil. After the oil has drained, turn the drain valve knob clockwise in order to close the drain valve.
If the engine is not equipped with a drain valve, remove the oil drain plug (1) in order to allow the oil to drain. If the engine is equipped with a shallow oil pan, remove the bottom oil drain plugs from both ends of the oil pan.After the oil has drained, the oil drain plug should be cleaned and installed. If necessary, replace the O ring seal. Tighten the drain plug to 34 N m (25 lb ft).Remove the container and disposal of the waste oil in accordance with local regulations.Replace the Oil Filter
Caterpillar oil filters are manufactured to Caterpillar specifications. Use of an oil filter that is not recommended by Caterpillar could result in severe 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.
Place a suitable container below the oil filter assembly. Remove the oil filter with a 1U-8760 Chain Wrench. Note: The following actions can be carried out as part of the preventive maintenance program.

Element with debris
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 filter. Consult your Caterpillar dealer in order to arrange for a further analysis if an excessive amount of debris is found in the oil filter.

Clean sealing surface (1).
Apply clean engine oil to O ring seal (2) for the new oil filter (3).
Do not fill the oil filters with oil before installing them. This oil would not be filtered and could be contaminated. Contaminated oil can cause accelerated wear to engine components.
Install the new oil filter (3). Spin on the oil filter until the O ring contacts the sealing surface (2). Then rotate the oil filter ¾ of a full turn. Remove the container and disposal of the waste oil in accordance with local regulations. Horizontal Oil Filter
