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 end plate gasket (4) and bearing
housing O‐ring (5). Position the seal end plate and
stationary seat over the shaft 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 45 ft. lbs. (540 in. lbs. or 6,2 m. kg.). Be
careful not to damage the stationary 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 and slide it 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.
Proceed with Impeller Installation and Adjust­
ment.
