REASSEMBLY
1. Assemble the adjusting legs to the adjusting leg brackets, and assemble the brackets to the
motor. Level the motor by individually adjusting the legs and locking them in place with the set
screws.
2. Install the adapter to the motor, with the drain cavity at the bottom. Insert the four bolts securing
the adapter to the motor. Tighten the bolts securely.
3. Assemble the stub shaft to the motor armature shaft. Do not tighten set screws.
4. Install the backplate by rotating it until the pins in the backplate engage the pins in the adapter
bracket.
For floating retainer models
Rotate the shaft until the floating pin hole is in a horizontal position. Insert the floating retainer, center
it in the shaft, and slide the impeller on the shaft. Hold the impeller tight against the shoulder on the
shaft and rotate the shaft one-fourth turn until the floating retainer drops and engages the impeller.
For threaded shaft models
Slide the impeller on the shaft and replace washer and castellated nut and cotter pin.
For both models
1. Assemble the clamp to the adapter, and install the casing.
2. Push the stub shaft onto the motor shaft until the impeller strikes the inside front face of the
backplate. Locate the stub shaft on the motor shaft allowing
1
/16" (1.5mm) maximum clearance
between the rear face of the impeller and the inside face of the backplate. Tighten the four set
screws on the stub shaft. Remove casing, impeller, impeller pin and backplate.
3. Slide the rubber deflector on the shaft until it seats the groove in the shaft.
Note:
If the deflector cannot be forced on with the fingers, a blunt instrument can be used to provide
additional force at the I. D. of the deflector.
4. Slide drive collar onto stub shaft, and locate per setting instructions in next section. Assemble the
spring, seal cup, o-ring seal and carbon seal, and install as a unit, taking care that slot in seal cup
is aligned with pin in drive collar. Gentle finger pressure will overcome o-ring resistance on the
shaft.
Note:
Do not lubricate seal with any type of oil or grease. The seal faces are lubricated by product
being pumped.
For floating retainer models
Install the backplate by rotating it until the pins in the backplate engage the pins in the adapter.
Rotate the shaft until the floating pin hole is in a horizontal position. Insert the floating retainer, center
it in the shaft, and slide the impeller on the shaft. Hold the impeller tight against the shoulder on the
shaft and rotate the shaft one-fourth turn until the floating retainer drops and engages the impeller.
For threaded shaft models
Install the backplate by rotating it until the pins in the backplate engage the pins in the adapter. Slide
the impeller on the shaft. Install washer's and thread the castellated nut to the shaft in a clockwise
direction until impeller hub contacts shaft shoulder. Use a combination of washers if needed to
ensure that the castellated nut is tight on the impeller before inserting and securing cotter pin.
