WATER PUMP SERVICE
Disassembly
Rotate the driveshaft counterclockwise to unlock
the impeller key. Remove the four impeller hous-
ing screws.
Slide the water pump off the driveshaft. Remove
the impeller key, O-ring, impeller plate, and gas-
ket. Discard the gasket.
Remove all the parts from the housing.
Inspection
Check impeller for overheating, hub separation,
and other wear or damage.
Check liner and wear plate for scoring, distortion,
and impeller material transfer.
Inspect the housing for cracks or melting.
Make sure gasket surface is clean and smooth.
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.
