age. Clean and polish the shaft sleeve, or replace it
if there are nicks or cuts on either end. If any com­
ponents are worn, replace the complete seal;
never mix old and new seal parts.
If a replacement seal is being used, remove it from
the container and inspect the precision finished
faces to ensure that they are free of any foreign
matter.
To ease installation of the seal, lubricate the pack­
ing rings and seal liner with water or a very small
amount of oil, and apply a drop of light lubricating
oil on the finished faces. Assemble the seal as fol­
lows, (see Figure 5).

Figure 5. GS1500 Seal Assembly
This seal is not designed for operation at
temperatures above 110
_F (43_C). Do not
use at higher operating temperatures.
Inspect the seal plate, seal liner, and the impeller
shaft for burrs or sharp corners, and remove any
that exist. Replace the seal liner (76) if wear or
grooves exist which could cause leakage or dam­
age to the seal packing rings. To replace the seal
liner, position the seal plate (48) on the bed of an
arbor (or hydraulic) press and use a new sleeve to
force the old one out. After the new liner is properly
installed, a 1/4 inch (6,4 mm) diameter hole must
be drilled through it to permit the flow of lubricant to
the seal assembly. Be careful to center the drill in
the threaded grease pipe hole and not damage the
threads. Deburr the hole from the inside of the seal
liner after drilling.
Slide the seal plate onto the shaft until fully seated
against the intermediate. Align the threaded seal
lubricant hole with the intermediate opening and
temporarily secure the seal plate to the intermedi­
ate with two capscrews and nuts (1/2 UNC X 1-1/2
inch long, not supplied).
Install the inboard rotating element with the cham­
fered side facing the shaft shoulder.
Subassemble the stationary seal seats, packing
rings, stationary washers, and spring onto the
