NOTE: For assembling purposes, apply a light
coat of oil to the O-rings before installing.
16. With a new O-ring in place, install the oil-injection
pump making sure the pump shaft slot and pump
driven gear shaft align. Secure with two screws
(coated with blue Loctite #243). Tighten the two
screws to 96 in.-lb.
CAUTION
Be sure the oil-injection pump/water pump driveshaft
is properly aligned with the slot of the oil-injection
pump. The pump will be damaged if these two compo-
nents are not aligned.
17. Position the ceramic/rubber seal retainer and seal
into the back side of the water pump impeller with
the ceramic face of the seal directed out.
CAUTION
When installing the seal into the impeller, assure that
all components are clean and free of any dirt or other
contaminants.
18. Using both thumbs, press the seal into position
making sure its marked side is positioned towards
the rubber seal cup; then apply a thin coat of
grease to the seal outer surface.

cap screw and washer. Be sure the rubber side of
the washer is lubricated with a light coat of grease
and directed toward the impeller. Apply blue Loc-
tite #243 to the threads of the cap screw and
tighten to 108 in.-lb.
NOTE: For assembling purposes, lubricate the
rubber side of the washer before installing.
If the rubber side of the washer is not positioned
toward the impeller, a coolant leak will result.

water pump cover seam; then install the dowel
pins into the crankcase.
NOTE: Do not allow sealant into the breather hole
