3. Remove the 3 motor hex cap screws (inner screws) on the seal housing and lift the seal
housing (3a). To ease the removal of the seal housing mount two of the screws removed
in the previous step in the two threaded holes of the seal housing (simultaneously or
alternating 2-3 turns at a time for each of them) (3b).

4. Turn the seal housing upside down and remove the stationary seat and O-ring. Remove
and discard the large O-ring used to seal between the seal housing and the pump
discharge head. Inspect the old seal seat before removal for any burrs or debris.
Lubricate the seat O-ring with a lubricant compatible with the seal elastomer and install
the new seat into the housing by pressing the seal housing with your thumb. DO NOT
USE EXCESSIVE FORCE and, if possible, place a clean soft cloth over the seal face to
protect the seal faces during installation.
5. Lubricate the shaft lightly with a water-based lubricant (e.g. P-80 lubricants). Insert the
small hook tool provided with the seal kit (5a) and rotate it in order to grab the seal with
the end hook (5b). Pull the rotary unit along the shaft (5c). Inspect the pump shaft for any
burns or debris. Any burrs should be ground smooth with (fine grit) emery paper.
