1. Assemble the impeller key (3–911–1) in the shaft key slot.
2. Check the impeller (4–002–0) and casing to determine the correct impeller rotation
and locate the impeller on the shaft per dimension “A” given in table.
NOTE: For impellers with replaceable rings, heat each new ring (4–004–9) and slide it
onto the impeller. Hold the rings against the impeller shoulder until they cool.
3. Apply 1/2” wide bead of Loctite or Permatex sealant to outboard end of shaft — 3” from
the impeller hub.
4. Slide sleeve (3–009–9) onto shaft, rotating the sleeve to evenly distribute the sealant
that is applied in step 3. On pumps that are built after 1991, install sleeve O-ring onto
the shaft, into the sleeve counterbore.
IMPORTANT: The pin in sleeve must seat in the impeller keyslot for proper sleeve
alignment.
5. Assemble the shaft sleeve nut (3–015–9).
IMPORTANT: Assure that dimension “C” is maintained. Drill a shallow recess in the
shaft through the set screw hold in the nut. Lock the nut in position with the set screw
(3–902–3).
6. Repeat steps 3 through 5 for the inboard shaft sleeve.
7. Assemble O-rings (3–914–2) in each casing ring (3–003–9) and slide ring onto the
impeller.
8. Press a new oil seal (3–177–9) into each stuffing box (3–073–9).
NOTE: Seal lip must point away from the bearing.
9. Lubricate and roll O-ring (3–914–1) into the groove in each stuffing box.
10.Slide each stuffing box onto the shaft but do not enter the oil seal. This will permit
installation of the deflector (1–136–9).
11.Slide the deflector over the shaft end; then push the shaft end through the oil seal and
slide the stuffing box fully onto the shaft.
12.Heat ball bearing (3–026–4), using either dry heat or a 10–15% soluble oil and water
solution.
IMPORTANT: Do not exceed 275°F.
13.Using gloves, press the heated bearing onto the shaft against the shaft shoulder.
