MAINTENANCE AND REPAIR

PAGE E − 7

old seal in an emergency, carefully wash all me-
tallic 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 the preci-
sion 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. If any components are worn, replace the com-
plete seal; never mix old and new seal parts.

Install the shaft seal as illustrated in Figure E−2.

Figure E−2. 26815−115 Seal Assembly

This seal is not designed for operation at
temperatures above 120

_ F (49_ C). Do not

use at higher operating temperatures.

Seal Installation

Do not unwrap a new seal assembly until time of
installation. Cleanliness of seal components is criti-
cal, especially the seal faces.

Clean the rotor shaft (50) and seal cavity area of the
motor housing (10). Be sure the area is dry and free

of lint and dirt. Check the seal bore for burrs or
nicks that might prevent a good seal. Apply a light
coating of oil to the bore.

Carefully remove the material stuffed into the seat
bore (or unwrap the shaft). Be sure no debris
stopped by the material falls into the motor cavity.

NOTE

When pressing seal components onto the shaft,
use hand pressure only. A push tube cut from a
length of plastic pipe will aid in installing seal com-
ponents. The I.D. of the push tube should be ap-
proximately the same as the I.D. of the seal spring.
