following procedures are to be followed.
Disassembly:

b) Loosen 8 volume bolts and slide pump away from
volume. Volume may be left in piping.
c) Insert large screwdriver between vanes of impeller
to hold the impeller and remove impeller lock screw

180 degrees apart or other suitable levers against

screwdrivers as levers will help. Do not attempt to
salvage the old carbon seal head.
f) Loosen four motor bolts and remove bracket from
motor.
g) Remove seal seat from bracket. Do not attempt to
salvage the old seal seat.
h) Inspect the stainless steel shaft sleeve. If scored,
it should be replaced unless it can be polished to
remove score marks.
i) Remove shaft sleeve if necessary. Heat sleeve to 200-
212 degrees to loosen and then slip from shaft. Force
of any type is not recommended.
Reassembly:
a) Clean motor shaft thoroughly. If solvents or liquids are
used, dry thoroughly. Apply Loctite RC/609 to inside
diameter of shaft sleeve. A vial of Loctite RC/609 is
supplied with the repair kit or replacement sleeve.
b) Install shaft sleeve onto motor shaft, tapping into
place to ensure it is sealed against motor shaft
shoulder.
c) Thoroughly clean seal seat cavity in bracket.
d) Place small amount of vegetable oil on white ceramic
seat cup and start it into seat cavity. Do not scratch
seat surface.
e) Tap white ceramic seat into cavity using a smooth
wood dowel, plastic rod or other soft material tool.
f) Install bracket onto motor using 4 bracket bolts.
Tighten bolts evenly.
g) Place a small amount of vegetable oil on the rubber
parts of black carbon seal head and slip black carbon
seal with black carbon face toward white ceramic
seat over stainless steel shaft sleeve. Turn black
carbon seal head 1/4 turn while pushing towards
white ceramic seat.
h) Push carbon seal head down shaft sleeve until carbon
face touches stationary ceramic seat.
