Figure E‐5. 46512-192 Seal Assembly
This seal is not designed for operation at
temperatures above 160
_
F (71
_
C). Do not
use at higher operating temperatures.
Lubricate the stationary seat O‐rings with water or
light oil, and install them in the stationary seat. In­
stall the stationary seal element in the stationary
seat. Press this stationary subassembly into the
front of the seal end plate (3) until it seats squarely
against the bore shoulder. Be careful not to dam­
age the seal face.
Install the seal plate gasket (4) and seal plate O‐
ring (33). Position the seal plate and stationary seat
over the shaft. Position the seal plate so that the
cast word “TOP” is upper most and secure it to the
bearing housing (9) with the hardware (6 and 7).
Torque the hardware to 90 ft. lbs. (1,080 in. lbs. or
12,4 m. kg.). Be careful not to damage the station­
ary element on the shaft threads.
NOTE
It is recommended that a tapered sleeve be in­
stalled over the threads of the impeller shaft to ease
installation of the rotating seal components.
Lubricate the shaft with a small amount of light oil
and slide the rotating subassembly (consisting of
rotating element, bellows and retainer), onto the
shaft. Apply firm, steady pressure on the seal re­
tainer as it slides onto the shaft until the seal faces
contact.
Install the seal spring. Lubricate the seal as indi­
cated in LUBRICATION after the impeller is in­
stalled.
If necessary to reuse an old seal in an emer­
gency, carefully separate the rotating and station­
ary seal faces from the bellows retainer and sta­
tionary seat.
A new seal assembly should be installed
