Motor and Pump Assembly & Disassembly Procedures
DISASSEMBLY PROCEDURE:
1 Remove (3) nuts from the back of the adaptor plate. Slide the pump end
out from the volute.
2 Holding the impeller to keep it from turning, loosen the washer head cap
screw, and remove the screw and gasket.
3 Slide the impeller off of the shaft and remove the key.
4 Remove the seal/sleeve as a unit by pulling it off of the shaft. Some
corrosion may prohibit movement and a lubricant may be used to
penetrate between the sleeve and motor shaft. With the impeller and key
removed, the shaft sleeve and the mechanical seal assembly can be
removed.
5 Remove O-ring from the shaft sleeve.
6 With the shaft sleeve removed, the seal rotating assembly can be pulled
off of the shaft sleeve.
7 Mark the adaptor plate and motor to insure proper re-assembly. Remove
(4) screws from the adaptor plate. Take the adaptor plate off the motor.
8 Remove O-ring from adaptor plate.

With the adaptor plate removed, the seal seat can be removed using a
screwdriver or by using your fingers.
INSPECTION OF THE COMPONENTS:
With pump end disassembled, clean all parts and check for worn and damaged
areas. Worn or damaged metal parts should be replaced. The mechanical
seal, gasket, O-ring, O-ring and washer head cap screw are replacement parts
that are provided in the kit. All old parts must be discarded and are not to be
reused.
ASSEMBLY PROCEDURE:
1 Push the mechanical seal seat squarely into the seal bore of the adaptor
plate by using fingers. A little lube can be used on the seal bore of the
adaptor plate. Make sure the ceramic side is up and it is fully seated.
2 Install the adaptor plate and tighten (4) screws, which hold it to the
motor face. Make sure the marks made in step 7 above line up.
3 Install O-ring into the groove of the adaptor plate.
