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 o-ring groove.
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 the impeller housing.
Lightly coat the exterior rim of the impeller cup
with Triple Guard grease. Install the cup in the
impeller housing. The cup locks in place in the
housing with two square index tabs.
Lightly coat the of the vanes of the impeller with
Triple-Guard grease. With a counterclockwise
rotation, install the impeller into the liner with the
slot for the impeller key facing out.
