Refitting
5 If a new pump is being fitted. it should be primed with engine oil before installation. Do this by turning its shaft while filling it with clean engine oil.

6 Locate a new gasket on the pump mounting flange, insert the pump shaft and bolt the pump into position.

7 Grease the rubber sealing ring of a new filter and screw it into position on the pump, using hand pressure only, not the removal tool.

8 Top-up the engine oil to replenish any lost during the operations.
