Drain the Oil
Hot oil and components can cause personal injury.Do not allow hot oil or 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, "Cat Dealer Service Tool Catalog" or refer to Special Publication, PECJ0003, "Cat Shop Supplies and Tools Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Do not drain the oil when the engine is cold. As the oil cools, waste particles settle on the bottom of the oil pan. The waste particles are not removed when the cold oil is drained. Drain the crankcase when the oil is warm. This method allows proper draining of the waste particles that are suspended in the oil.Failure to follow this recommended procedure will allow the waste particles to be recirculated through the engine lubrication system with the new oil.
After the engine has been operated at normal operating temperature, STOP the engine.
Drain the oil according to the equipment on the engine.Note: Drain the oil into a suitable container. DO NOT drain the oil into the bilge sump. Dispose of the oil according to local regulations.

Oil drain plugNote: If a suction device is used to remove oil from the oil pan, ensure that the suction device is clean to keep dirt out of the oil pan. Be careful not to strike the engine oil suction tubes or the piston cooling jets.
If the engine does not have a drain valve or a pump, remove an oil drain plug. Allow the oil to drain. After the oil has drained, clean the drain plug and clean the fitting for the drain plug. Install the drain plug. Tighten the drain plug to 145 15 N m (105 10 lb ft).
If the engine has an oil drain valve, open the valve. After the oil has drained, close the valve.
If the engine has a pump for removing dirty oil, connect a hose to the outlet of the pump. Place the hose in a suitable container. Open the valve for the drain line. Turn the two marks on the valve so that one mark points to the pump and the second mark points to the drain line. Operate the pump until the crankcase is empty. Close the valve to the drain line. Disconnect the hose.
If the oil drain valve has a "quick connect" coupling, attach the coupling. Open the drain valve in order to drain the crankcase. After the oil has drained, close the drain valve. Disconnect the coupling.
Replace the engine oil filter elements before filling the crankcase with new oil.Replace the Oil Filter Elements
Replace the engine oil filters when any of the following conditions occur:
Every oil change
The engine oil filter differential pressure reaches 103 kPa (15 psi).
The oil filter elements have been used for 1000 service hours.Note: Do not attempt to clean the used oil filters. Used oil filters will retain waste particles. The used oil filters would not filter the oil properly.Service tools are available to aid in the service of oil filters. Consult your Cat dealer for the part names and the part numbers. Follow the instructions that are supplied with the service tools. If the service tools are not used, perform the following appropriate procedure.Replacing the Engine Oil Filters With the Engine Stopped
Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
Perform the following procedure after the oil has been drained.Note: Use this procedure if the engine oil filters do not have a control valve.

(1) Bolts (2) Cover (3) Plug (4) Drain valve (5) DrainNote: Drain the oil into a suitable container. Dispose of the oil according to local regulations.
Connect a hose to drain (5). Place the other end of the hose into a suitable container in order to collect the oil.
Open drain valve (4). Remove plug (3). Allow the oil to drain. Clean the plug and install the plug. Close the drain valve. Remove the hose from the drain.Note: Some oil will remain in the housing after the oil has been drained. This oil will pour out of the housing when cover (2) is removed. Prepare to catch the oil in a suitable container. Clean up any spilled oil with absorbent pillows or towels. DO NOT use absorbent particles to clean up the oil.
Personal injury can result from parts and/or covers under spring pressure.Spring force will be released when covers are removed.Be prepared to hold spring loaded covers as the bolts are loosened.
