Figure E‐6. 46513-153 Seal Assembly
This seal is not designed for operation at
temperatures above 160
_
F (71
_
C). Do not
use at higher operating temperatures.
If the wear plate (26) was removed, secure it to the
seal plate (3) with the hardware (24 and 25).
If the seal plate was removed, install the seal plate
gasket (4) and bearing housing O‐ring (5). Lubri­
cate the O‐ring with light grease. Position the seal
plate over the shaft and secure it to the bearing
housing with the hardware (6 and 7).
To prevent damaging the shaft sleeve O‐ring (35)
on the shaft threads, stretch the O‐ring over a piece
of tubing 1‐1/2” I.D. x 1‐3/4” O.D. x 2‐inches long
(38 mm x 45 mm x 51 mm). Slide the tube over the
shaft threads, then slide the O‐ring off the tube and
onto the shaft. Remove the tube, and continue to
slide the O‐ring down the shaft until it seats against
the shaft shoulder.
When installing a new cartridge seal assembly, re­
move the seal from the container, and lubricate the
external stationary seat O‐ring with light oil. Slide
the seal assembly onto the shaft until the external
stationary seat O‐ring engages the bore in the seal
plate.
Clean and inspect the impeller as described in Im­
peller Installation and Adjustment. Install the full
set of impeller shims (34) provided with the seal,
and screw the impeller onto the shaft until it is
seated against the seal (see Figure 7).
