Oil Pump Assembly (Style B)

Oil pump is mounted inside oil pan. If service is required,
continue with Disassembly, Inspection, and Reassembly.
Disassembly
1. Remove screws.
2. Lift oil pump assembly from oil pan. Remove outer
gerotor gear from oil pan.

relief hole of oil pan. If ball and spring fall out of
pressure relief hole, see reassembly for correct
installation.
Inspection
Inspect oil pump housing, gear, and rotors for nicks,
burrs, wear, or any visible damage. If any parts
are worn or damaged, replace oil pump assembly.
Check oil pickup screen for damage or restriction,
replace if necessary. Disassembly of oil pump is not
recommended.
Reassembly
1. Lubricate outer gerotor gear with oil. Install outer
gerotor gear through shaft of oil pump, around inner
gerotor gear. Matching molding dots on inner and
outer gerotor gears is not necessary and will not
affect oil pump effi ciency.
2. Reinstall ball, then spring into pressure relief hole of
oil pan.
3. Install oil pump inserting center shaft into
corresponding recess in oil pan. Secure oil pump by
torquing screws (in no specifi c sequence) to 9.0 N·m
(80 in. lb.).
4. After torquing, rotate gear and check for freedom of
movement. Make sure there is no binding. If binding
occurs, loosen screws, reposition pump, retorque
screws and recheck movement.
