or emery cloth. If excessive wear exists, the shaft
will have to be replaced.

The seal is not normally reused because wear pat-
terns on the finished faces cannot be realigned
during reassembly. This could result in premature
failure. If necessary to reuse an old seal in an emer-
gency, carefully wash all metallic parts in fresh
cleaning solvent and allow to dry thoroughly.

Handle the seal parts with extreme care to prevent
damage. Be careful not to contaminate precision
finished faces; even fingerprints on the faces can
shorten seal life. If necessary, clean the faces with a
non-oil based solvent and a clean, lint-free tissue.
Wipe lightly in a concentric pattern to avoid
scratching the faces.

Inspect the seal components for wear, scoring,
grooves, and other damage that might cause leak-
age. Clean and polish the shaft sleeve (41), or re-
place it if there are nicks or cuts on either end. If any
components 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.

To ease installation of the seal, lubricate the O-
rings, bellows and shaft sleeve with water or a very
small amount of oil, and apply a drop of light lubri-
cating oil on the finished faces. Assemble the seal
as follows, (see Figure E−3).

Figure E−3. 46512−062 Seal Assembly

This seal is not designed for operation at
temperatures above 160

_F (71_C). Do not

use at higher operating temperatures.

Lay the seal plate on a flat surface with the impeller
side down. Press the oil seal (19) into the seal plate
(72) with the lip positioned as shown in Figure
E−1.

Turn the seal plate over so the impeller side is up. If
removed, use a hammer and a drift pin to install the
