Assembly
Apply a drop of Adhesive 847 in the seal ring
groove at each of the four ribs.
IMPORTANT: Do not allow any sealer to get into
the air bleed groove in the impeller housing. If this
groove is blocked by adhesive, the pump will lose
its prime and will not pump water.
Install the O-ring in groove in the impeller housing.
Lightly coat the exterior rim of the impeller cup
with Gasket Sealing Compound. Install the cup in
the impeller housing. The cup locks in place in the
housing with a square index tab.
Make sure vent hole in impeller cup is open.
Install the water tube grommet with the inside
taper facing up.
Apply Triple-Guard grease to screw threads and
install the impeller housing cover and tighten
screws to a torque of 24 to 36 in. lbs. (3 to 4 N·m).
Apply Adhesive 847 to flat side of the impeller
housing grommet. Install the grommet, flat side
down.
Lightly coat the inside of the liner with Triple-
Guard grease. With a counterclockwise rotation,
install the impeller into the liner with the slot for the
impeller key facing out.
