_
C). Do not
use at higher operating temperatures.
Install the inboard snap ring (43) in the groove in
the I.D. of the seal housing (7). Make sure the lu-
brication channel in the seal housing alignes with
the opening in the bearing housing and secure the
seal housing to the pedestal with the hardware (10
and 11).
Lubricate the I.D. of the seal housing with light oil.
Position the inboard rotating element on the shaft
with the chamfer facing the shaft shoulder. Slide
the element onto the shaft until fully seated against
the shaft shoulder.
Subassemble the inboard stationary seat, packing
ring and spring washer, and press the subassem-
bly into the lubricated seal liner. A push tube cut
from a length of plastic pipe would aid this installa-
tion. The O.D. of the tuve should be slightly smaller
than the I.D. of the seal liner.
Install the spacer sleeve and spring.
Subassemble the outboard stationary seat, pack-
ing ring and spring washer. Press this subassem-
bly into the seal liner.
Install the outboard rotating element with the
chamfered side facing the impeller end of the shaft.
Install the seal washer (45) with the chamfered side
facing the outboard rotating element.
Install the automatic grease cup (14) in the bearing
housing. After the impeller is installed, lubricate the
seal assembly as indicated in LUBRICATION.
Impeller And Wear Ring Installation
If the wear ring (6) was removed for replacement,
remove the jacking screws, align the mounting
holes, and press the wear ring into the pump cas-
ing until fully seated. Apply ‘Never-Seez’ or equiva-
lent compound to the hardware (4 and 5) and se-
cure the wear ring to the pump casing.
