9 Install the new stationary seal seat into the faceplate by
firmly pressing it down until it bottoms. The disk should
be clean. If needed, wipe it with alcohol and a soft lint
free cloth.
10 Replace the faceplate on the motor housing extension,
being careful to avoid shaft contact. This may need to be
gently tapped down until tight to the housing. Be sure to
check that the stainless steel plate is flush to the extender
plate face.
11 Install the special installation tool (item #180212-095) on
the top of the shaft making sure it is tight to the flat base of
the impeller to protect the seal from sharp edges during
seal installation.
12 Apply a liberal amount of non-petroleum based lubricant
on the outside of the special plastic installation tool.
13 Wipe any excess lubricant off of the stationary silicon
carbide seal face with a lint free cloth and alcohol to ensure
the surface is clean.
14 Install the new rotating seal element and spring assembly
by gently pushing it (graphite ring first) over the installa-
tion tool and onto the shaft until the graphite ring presses
tightly against the stationary seal seat. The seal spring may
be compressed slightly.

20 Ensure the gasket is properly seated in the pump casing
(volute) gasket groove. Holding the motor body, insert
the impeller straight into the volute. Verify the gasket was
not dislodged during insertion, and is still seated properly.
Hold the motor body steady while fastening the four bolts
that attach the motor to the pump casing (volute). Tighten
evenly and diagonally. There should be a small, even gap
of about 0.02" (0.5 mm) between the motor flange and the
pump casing (volute).
21 Follow the start up instructions (File no. 10.84)
and check for leaks.
