MAINTENANCE & REPAIR PAGE E - 11
Inspect the seal components for wear, scoring,
grooves, and other damage that might cause leak­
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
and O‐rings with a very small amount of light lubri­
cating oil. See Figure 5 for seal part identification.

This seal is not designed for operation at
temperatures above 160
_
F (71
_
C). Do not
use at higher operating temperatures.
Lubricate the stationary seat O‐rings with water or
light oil, and install them in the stationary seat. In­
stall the stationary seal element in the stationary
seat. Press this stationary subassembly into the
front of the seal plate (22) until it seats squarely
against the bore shoulder.
Install the seal plate gasket (3). Position the seal
plate and stationary seat over the shaft and secure
it to the bearing housing (5) with the hardware (20
and 21). Be careful not to damage the stationary
element on the shaft threads.
NOTE
It is recommended that a tapered sleeve be in­
stalled over the threads of the impeller shaft to ease
installation of the rotating seal components.
Lubricate the shaft with a small amount of light oil
and slide the rotating subassembly (consisting of
the rotating element, bellows and retainer) onto the
shaft. Apply firm, steady pressure on the seal re­
tainer until it slides onto the shaft and the seal faces
contact.
Install the seal spring. Lubricate the seal as indi­
cated in LUBRICATION after the impeller is in­
stalled.
