Jeep 68195993AD Engine Oil Pump

On this type of engine, the oil pressure relief valve cannot be unbolted from the oil pump housing; if you unbolt it, then the whole oil pump must be replaced by a new one. That is why, for the Hemi engine, only complete oil pumps are produced, which are installed directly in the engine. However, to remove the oil pump it is necessary to first disconnect the cable coming from the negative terminal of the battery and later drain the cooling system. Then, first, take off the timing chain cover and the oil pan. Subsequently, take out the bolt holding the pick-up tube assembly with the tube lowered away from the OIL pump The OIL pump with the mount bolts is then taken out of the engine block. To install, locate the pump on the engine smartly so that the rotor of the pump stands in parallel to the crankshaft drive and then fasten and tighten the oil pump mounting screws. Insert another O-ring to the oil pump pick-up tube and screw the tube to the pump and tighten the bolt. The rest of the installation is in contrast done in the reverse of the removal sequence. Last, add the type and amount of engine oil into the crankcase, replace the oil filter and coolant as required. Revolutionize the engine and make sure the oil pressure and whether there is any leakage or not.
