3. Install the shaft sleeve and
rotating element as a unit.
a. Place the sleeve in an upright
position with the smaller end
facing up.
b. Lubricate the shaft sleeve and
rotating element.
c. Be sure to install a key (#23A)
in the motor shaft before
installing the sleeve and seal
assembly.
d. Holding the element assembly
between the thumb and index
finger of both hands, refer to
Figure 4-13, slide the assem-
bly over the sleeve until the
spring holder rests against the
shoulder of the sleeve.
e. The element must slide freely
up and down on the sleeve. It
is necessary to maintain some
downward pressure on the
element because the spring
tension could dislodge the
seal portion of the element.
f. Holding the assembled sleeve
between the thumb and index
finger, slide the assembly onto
the motor shaft.
g. Push the sleeve on until it
comes in contact with the
locking collar.
h. Position the collar over the
sleeve end and push the
sleeve on until the holder is 1/
32" to 1/16" below the impeller
wearing surface of the motor
bracket.
i. While maintaining inward
pressure on the sleeve with
one hand, line up the collar
setscrews with the key in the
shaft sleeve, one setscrew on
each side of the key.
j. Tighten the setscrews snugly.
k. Pressure can now be re-
leased, the sleeve should
remain in position. The spring
holder must be below the
impeller wearing surface of
the motor bracket for proper
impeller operation.
4. Install the impeller.
a. Place a key (#23) in the shaft
sleeve.
b. The impeller is a slip fit and
should slide on firmly but
easily until it stops against the
impeller wearing surface.
Force should not be required
to install the impeller in the
correct position.
