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
contaminents.
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.
19. Place the impeller into position and secure with a
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.
CAUTION
If the rubber side of the washer is not positioned
toward the impeller, a coolant leak will result.
20. Apply high-temperature sealant to the crankcase/
water pump cover seam; then install the dowel
pins into the crankcase.
NOTE: Do not allow sealant into the breather hole
in the crankcase. If sealant gets into the hole, care-
fully remove before proceeding.
