Oil pump disassembly

Disassembly

Remove the pump from the engine. Unscrew the fixing screws and remove the pump cover. Remove the O-ring (see fig. 2B.51).

Examination

Clean the rotors and the inside of the pump housing, and visually inspect the pump parts for wear and damage. Check pump clearances using a feeler gauge blade (see corresponding description for HCS and Endura-E engines).

Assembly

When assembling the pump, ensure that the installation marks on the inner and outer rotors are aligned (see fig. 2V.52).
