6.3 Reassembly
6.3.1 Replace the seal
The inside and outside seal can be replaced without removing the motor.
1. Remove the coupling guard.
2. Remove the flush line from the seal cap.
3. If an outside seal, put seal clips/pins (remove setscrew for where the pin needs to be
placed) in the seal and then loosen the set screws that hold the seal on the shaft.
4. Remove the coupler halves. Tape the collar rings together in pairs as assembled
previously.
The shaft drops down when the coupling is removed.
5. If an outside seal, remove the seal.
6. Remove the seal cap or seal gland through the space between shafts.
a) Remove the seal seat from the seal cap or gland.
b) If an inside seal, remove the seal using a pair of screwdrivers, to pry out the seal.
7. Clean the seal box, seal cap, or gland and shaft.
CAUTION:
Avoid touching the faces of the seal and getting them dirty.
8. Place the seal seat in the seal cap or gland.
9. For an outside seal:
a) Install the seal seat with seal cap or gland (including the gaskets on either side of the
seat) over the end of the shaft and fasten to the motor bracket with four cap screws
and washers. Tighten seal gland cap screws evenly to avoid misalignment one
quarter turn past hand tight.
b) Leave the seal holding clips/pins on the rotating part of the seal, lubricate the bore of
the seal with soapy water or other suitable lubricant such as International Products
Corporation P-80
®
, and install the rotating part of the seal on the shaft with the
rotating face toward the seal seat.
c) After the coupling assembly (see below), tighten the seal set screws on the shaft and
remove the seal holding clips/Pins. If pin used remove pin and tighten setscrews on
shaft. The seal is now set. Keep the seal holding clips/pins in case the seal has to be
removed in the future
