MAINTENANCE & REPAIR PAGE E - 6
Inspect the seal components for wear, scoring,
grooves, and other damage that might cause leak­
age. Clean and polish the shaft sleeve, or replace it
if there are nicks or cuts on either end. If any com­
ponents are worn, replace the complete 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. Discard the spring centering washer in­
cluded with the seal. It is not used in this applica­
tion.
To ease installation of the seal, lubricate the shaft
sleeve with water or a very small amount of oil, and
apply a drop of light lubricating oil on the finished
faces. Assemble the seal as follows, (see Figure 2).

Figure 2. Seal Assembly
This seal is not designed for operation at
temperatures above 160
_F (71_C). Do not
use at higher operating temperatures.
Slide the slinger ring (17) onto the shaft. Install the
stationary seat and press this stationary subas­
sembly into the intermediate until fully seated. After
installation, wipe the sealing face lightly in a con­
centric pattern with a clean, lint‐free tissue.
Position the intermediate (22) and stationary sub­
assembly over the shaft and against the motor. Se­
cure the intermediate to the motor with the hard­
ware (20 and 21).
Slide the rotating subassembly (consisting of the
element, bellows and retainer) over the lubricated
shaft sleeve until the rotating element is just flush
with the chamfered end of the sleeve. Slide the
sleeve over the shaft until the sealing faces con­
tact. Continue to press the shaft sleeve through the
seal assembly until it seats squarely against the
shaft shoulder.
Install the seal spring and spring retainer (11 and
12).
