Figure 6. Seal Assembly
This seal is not designed for operation at
temperatures above 160
_F (71_C). Do not
use at higher operating temperatures.
Install the oil seal (17) in the seal plate (36) with the
lip positioned as shown in Figure 3. Make sure the
oil seal is fully seated.
Install the seal plate gasket (42) and 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 interme-
diate, and secure the seal plate to the intermediate
with the hardware (37 and 38).
Assemble the O-ring into the stationary element.
Press the stationary element into the seal plate
bore until fully seated. Use caution not to damage
the sealing face. After installation, wipe the sealing
face with a clean, lint-free cloth in a concentric pat-
tern to remove any dirt or fingerprints.
Subassemble the rotating element into the rotating
portion of the seal assembly with the chamfered
side facing out. Slide the rotating portion of the seal
assembly onto the shaft sleeve (11) until the rotat-
ing element is just flush with the chamfered end of
the sleeve. Slide the sleeve onto the shaft until the
seal elements contact. Continue to push the sleeve
through the seal until the sleeve seats squarely
against the shaft shoulder. Be careful not to roll or
damage the lip of the seal plate oil seal (17).
Install the seal spring and spring retainer (12).
Reinstall the bottle oiler and piping (14, 15 and 16).
Lubricate the seal as indicated in LUBRICATION,
after the impeller has been installed.
