age. If any components are worn, replace the com
plete seal; never mix old and new seal parts.
If a replacement seal is being used, remove it from
the container and inspect the precision finished
faces to ensure that they are free of any foreign
matter.
To ease installation of the seal, lubricate the shaft
sleeve, shaft sleeve O‐ring and the external station
ary seat O‐ring with a very small amount of light lu
bricating oil. See Figure 8 for seal part identifica
tion.

Figure 8. Cartridge 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 seal plate (4) was removed, install the seal
plate gasket (5). Position the seal plate over the
shaft and secure it to the bearing housing with the
hardware (8 and 9).
To prevent damaging the shaft sleeve O‐ring (25)
on the shaft threads, stretch the O‐ring over a piece
of plastic tubing that the I.D. is a little larger than the
O.D. of the shaft. 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,
remove the seal from the container, and remove
the mylar storage tabs, if so equipped, from be
tween the seal faces.
Some cartridge seal assemblies are
equipped with mylar storage tabs between
the seal faces. These storage tabs must be
removed before installing the seal.
