Remove Engine Oil Pump
Start By:a. remove fuel transfer pumpFluid Spillage Containment
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to "Tools And Shop Products Guide", NENG2500 for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose fluids according to local regulations and mandates.1. Drain the coolant from the cooling system into a suitable container for storage or disposal.2. Drain the oil from the engine oil pan into a suitable container for storage or disposal. 3. Remove all bolts (1) and (2) to remove adapter (3) from the engine. 4. Remove all the bolts and remove engine oil pump (4) from the engine. The weight of the engine oil pump is approximately 39 kg (85 lb).Install Engine Oil Pump
The engine oil pump shaft must turn by hand and the pump must have oil for lubrication before it is installed. 1. Put clean engine oil on the O-ring seals and put engine oil pump (1) in position. Make sure the splines on the pump shaft are correctly engaged with the splines of the engine oil pump drive. Install the bolts to hold the engine oil pump in position. 2. Put the gaskets and adapter (2) in position. Install the bolts to hold the adapter and gaskets in position.3. Fill the engine with oil to the correct level.4.
