Figure E−5. 12364D Seal Assembly
This seal is not designed for operation at
temperatures above 160
_F (71_C). Do not
use at higher operating temperatures.
Inspect the seal plate (35) and the impeller shaft
(26) for burrs or sharp corners, and remove any
that exist. Install the oil seal (16) in the bore of the
seal plate with the lip positioned as shown in Figure
E−2. Make sure the oil seal is fully seated.
Position the seal plate against the intermediate. Be
careful not to damage the oil seal lip on the shaft
threads. Align the bottle oiler hole with the opening
in the intermediate, and secure the seal plate to the
intermediate with hardware (36 and 37).
Lubricate the stationary seat O-ring with light oil
and press the assembled stationary seat and sta-
tionary element into the seal plate bore until fully
seated. A push tube cut from a length of plastic
pipe would aid this installation. The I.D. of the tube
should be approximately the same as the I.D. of the
seal spring.
Subassemble the stationary and rotating element
into the retainer and bellows. Apply a drop of light
oil on the precision finished faces; never use
grease. Use even pressure to carefully press this
subassembly onto the sleeve (75) with the rotating
element facing the chamfered end of the sleeve.
Position the sleeve on the shaft with the chamfered
end toward the seal cavity. Slide the sleeve onto
the shaft until it seats against the shaft shoulder.
Install the seal spring and spring holder.
Reinstall the bottle oiler and piping (13, 14 and 15).
Lubricate the seal as indicated in LUBRICATION,
after the impeller has been installed.
