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 circular 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. Seal Assembly
This seal is not designed for operation at
temperatures above 120
_ F (49_ C). Do not
use at higher operating temperatures.
Do not unwrap a new seal assembly until time of
installation. Cleanliness of seal components is criti­
cal, especially the seal faces.
Carefully remove the material stuffed into the seat
bore (or unwrap the shaft). Be sure no debris
stopped by the material falls into the mounting
plate.
Install the dust seal (109) in the lower mounting
plate (98) as shown in Figure E‐1.
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.
Install the snap ring on the rotor shaft just below the
dust seal.
Unpack the stationary seat and stationary element.
Place a clean tissue over the sealing face of the sta­
tionary element and subassemble the stationary
element into the stationary seat.
Apply a light coating of oil to the seal seat bore in
the seal chamber (9). Position the stationary sub­
assembly in the seal chamber bore with the sealing
face up and cover the seal face with a clean tissue.
