17. Install thrust collar bearing (237) (chamfered side
in) into bore of thrust bearing with the tolerance
ring (Fig. J). Ensure bearing is fully seated in
holder.
NOTE: To ease assembly and minimize the risk of
damage to the thrust bearing (237), the use of an
arbor press is recommended during installation
(Fig. K). Use a small amount of O-ring lube on
the tolerance ring and O.D. of thrust collar before
assembly.
18. Install one of the thrust bearing assemblies onto
the shaft with the bearing facing down (towards
the driven magnet assembly)
(Fig. L). Be careful to align the keyway on the
thrust bearing assembly with the thrust bearing
key (178S) on the shaft.
19. Install thrust bearing holder gasket (428C) into
groove on back of thrust bearing assembly on
shaft (Fig. L). Use a small amount of O-ring lube
in groove to hold gasket in place.
20. Install the other thrust bearing holder onto the
shaft with the bearing facing up (towards the
impeller end) (Fig. L). Again, carefully align the
keyway with the key.
21. Place the third spacer gasket (360) over driven
shaft and shoulder against inboard thrust bearing
assembly (Fig. L).
NOTE: Ensure thrust holder key and keyways are
free of burrs.
NOTE: Take a pencil and make a reference mark
locating the thrust bearing key (178S) in relation
to the frame adaptor. This will help align the
keyway of the thrust bearing assemblies (212) with
the thrust bearing key (178S).
22. Place O-ring installation tool on driven shaft
(122A) and install impeller washer (199) and bolt
(198) as before (Fig. B). Install two shaft O-rings
(497P) and then remove tool.
NOTE: Tape first groove on shaft to allow O-ring
to slide over. O-ring may have to be heated to seat
in groove. Do not overheat O-rings.
