Revision: 2006 January2006 M35/M45
ASSEMBLY
NOTE:
Secure oil pump in a vise if necessary.
CAUTION:
Use copper plates when securing in a vise.
1. Apply multi purpose grease to oil seal lips (1). Apply power

INSPECTION AFTER DISASSEMBLY
Body Assembly and Rear Cover Inspection
Check body assembly and rear cover for internal damage. Replace rear cover if it is damaged. Replace oil
pump assembly if body assembly is damaged.
Cartridge Assembly Inspection
Check cam ring, rotor and vane for damage. Replace cartridge assembly if there are.
Side Plate Inspection
Check side plates (front and rear) for damage. Side plates (front and rear) must be replaced as a set if they
are damaged.
