In this design, the oil pump is a complete unit that cannot be serviced or repaired and no spare parts or repair procedures are offered by the manufacturer. To demould the oil pump, it requires dismantling the oil pan and, in addition, two bolts holding the oil pump pick-up tube to the oil pump. Third, take off the
Timing Chain cover, timing chains, chain guides and crankshaft sprocket. That is followed by the removal of the oil pump mounting bolts and the removal of the pump from the engine block. For instance, in installation, one should check the condition of the O-ring gasket of the pick-up tube, and replace if necessary. Mount the oil pump on the engine and secure it with the appropriate bolts to the tightness required and with the primer oil the oil pick up port the oil pump should be rotated manually. The final steps on the installation process are the exact opposite of the removal process of Mutual TLS. Last but not the least, add the recommended grade of oil and the needed volume, switch on the engine and look for any sign of leakage.
