MAINTENANCE & REPAIR PAGE E − 13
Inspect the seal components for wear, scoring,
grooves, and other damage that might cause leak-
age. Clean and polish the seal liner, or replace it if
there are nicks or cuts on either end. If any compo-
nents 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 E−5).

Figure E−5. GS1250 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 (34), seal liner (74), and the
impeller shaft for burrs or sharp corners, and re-
move any that exist. Replace the seal liner 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 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 in-
stalled, a 1/4-inch (6,4 mm) diameter hole must
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 and gasket (40) onto the shaft
until fully seated against the intermediate. Align the
threaded seal lubricant hole with the intermediate
opening, and secure the seal plate to the interme-
diate with the hardware (35 and 36).
Install the inboard rotating element with the cham-
fered side facing the shaft shoulder. Subassemble
