Figure 3. Seal Assembly
This seal is not designed for operation at
temperatures above 160
_F (71_C). Do not
use at higher operating temperatures.
Position the seal plate (36) on a flat surface with the
impeller side down. Apply a light coat of oil to the oil
seal (14) and press it into the seal plate with the lips
positioned as shown in Figure 1.
With the seal plate on a flat surface with the impel­
ler side up, press the stationary subassembly (con­
sisting of the stationary seat, O‐rings and station­
ary element) into the seal plate until the stationary
seat bottoms against the seal plate bore. A push
tube cut from a length of plastic pipe would aid this
installation. The I.D. of the pipe should be approxi­
mately the same diameter as the I.D. of the seal
spring.
Slide the seal plate over the shaft until fully seated
against the pedestal (19). Be careful not to dam­
age the oil seal lip on the shaft threads.
Align the threaded seal lubricant hole with the ped­
estal opening and temporarily secure the seal p
late using two capscrews and nuts (3/8‐16 UNC X 1
1/2 inch long, not supplied).
Slide the rotating subassembly (consisting of the
rotating element retainer and bellows) onto the lu­
bricated shaft sleeve until the rotating element is
just flush with the chamfered end of the sleeve.
Slide the sleeve and rotating subassembly onto
the shaft until the seal elements contact. Continue
to push the sleeve through the seal until it bottoms
against the shaft shoulder. Be careful not to dam­
age or roll the lips of the oil seal (14).
Install the seal spring and spring centering washer
(59).
Reinstall the bottle oiler and piping (10, 11, 12 and
13), and lubricate the seal assembly as indicated in
LUBRICATION, after the impeller has been in­
stalled.
