CYLINDER GP 4T4575 - Caterpillar

Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
Ensure that the engine is stopped before performing this procedure. Attach a DO NOT OPERATE tag to the starting controls.
Drain the crankcase with the engine oil warm, immediately after the engine is stopped. This draining method allows the waste particles that are suspended in the engine oil to be drained properly. 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.
Shut off the valve on the makeup oil tank.
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.
Use one of the following methods to drain the engine oil. Use the method that corresponds to the equipment on the engine.Note: If a suction device is used in order to remove the engine oil, ensure that the suction device is clean. This will prevent dirt from entering the engine oil pan. Be careful not to strike the engine oil pump's suction tubes or the piston cooling jets.

Location of the drain or plug for the engine oil
If the engine has an drain valve, open the valve. After the engine oil has drained, close the valve.
If the engine has a pump for removing the engine oil, connect one end of the hose to the outlet of the pump. Place the other end of the hose in a suitable container. Open the valve for the drain line. Operate the pump until the crankcase is empty. Close the valve to the drain line. Disconnect the hose.
If the drain valve has a quick connect coupler, attach the coupler. Open the drain valve. After the engine oil has drained, close the drain valve. Disconnect the coupling.
If the engine does not have a drain valve or a pump, remove the engine oil drain plug. After the engine 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).Note: Make sure that all of the used engine oil is removed. If necessary, remove a side cover and inspect the engine oil pan. Dirty engine oil that remains in the oil pan will act as a catalyst which drastically reduces the service life of the new engine oil. If care is not taken, as much as 95 L (25 US gal) of used engine oil can remain in the engine oil pan.
Replace the engine oil filter elements before filling the crankcase
