Pre-Lubrication of Oil Pump Parts
The oil pump parts must be completely immersed
in clean refrigerant oil to lubricate the pump
assembly thoroughly.
Do not smear oil on with
your fingers!
It cannot be stressed enough that
the oil must be absolutely clean and that it
thoroughly covers the part. Compressor oil and an
oil cup for holding clean compressor oil are
provided in Oil Pump Kit P/N 22-1160. If a
number of pumps are going to be done in quick
succession, the oil may be used for three or four
pumps if it is kept covered and checked frequently
for contamination.
Installation
1. Install a new O-ring on the oil pump shaft.
2. Immerse the O-ring and shaft in oil and then
install the pump shaft into the crankshaft.
3. Immerse the inner wear plate in oil and install
it in the pump housing. Make sure it lines up
with the pin in the bottom of the housing.
Check the plate for proper seating against the
housing, it should not wobble.
NOTE: Both of the pump wear plates and the
gerotor gears can be installed with either
face in or out.
NOTE: The new oil pump gerotor and wear
plates must be kept clean. If the parts pick up
any debris, they must be wiped clean. Parts
must be handled carefully to prevent damage
or contamination.
4. Install the key into the keyway on the shaft.
5. Immerse the inner gerotor gear in oil and
carefully slide it on the shaft. Make sure the
key stays in place.
6. Immerse the outer gerotor gear in oil and
install it.
7. Immerse the eccentric ring and roll it into
pump. The ring should be positioned so that
the pin in the pump cover will align with the
slot in the eccentric ring.
8. Install the Y spring. Roll the pump so it ends
up in the 12:00 o'clock position.

9. Immerse the outer wear plate in oil and install
it in the pump housing. Install the outer wear
plate with the notch aligned with the eccentric
ring.
CAUTION: Do not save oil from one day
to the next.
