Figure 4. 25271-903 Seal Assembly
This seal is not designed for operation at
temperatures above 160
_F (71_C). Do not
use at higher operating temperatures.
Inspect the impeller shaft for distortion, nicks,
scratches, or damage to the shaft keyway. Dress
small nicks and burrs with a fine file or emery cloth.
If the shaft is defective, refer to GEARBOX DISAS­
SEMBLY and replace the shaft.
Lubricate the stationary element O‐ring with a light
coat of oil. Place a clean, lint‐free tissue over the
seal face, and use thumb pressure to press the ele­
ment and O‐ring into the pump casing until fully
seated. Be careful not to damage the seal face. Af­
ter installation wipe the seal face in a concentric
pattern with a clean, lint‐free cloth to remove any
fingerprints.
NOTE
If the pump casing was removed, install the casing
O‐ring and gasket (18 and 19) on the pump casing
studs. Carefully slide the casing over the shaft, and
secure it to the gearbox with the nuts (15).
Install a tapered sleeve (see Figure 5) over the shaft
keyway to ease installation of the rotating portion of
the seal. This tool can be made from steel tubing or
pipe.
