non-oil based solvent and a clean, lint-free tissue.
Wipe lightly in a concentric pattern to avoid
scratching the faces.
Inspect the seal components for wear, scoring,
grooves, and other damage that might cause leak-
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 seal
liner (8) with water or a very small amount of oil,
and apply a drop of light lubricating oil on the fin-
ished faces. Assemble the seal as follows, (see Fig-
ure 3).

Figure 3. GS1000 Seal Assembly
This seal is not designed for operation at
temperatures above 110
_F (43_C). Do not
use at higher operating temperatures.
Before installing the seal, inspect the bore of the
seal liner (8) for wear or grooves which might cause
leakage or damage to the seal packing rings. If the
seal liner requires replacement, remove the seal
plate assembly as described in Seal Removal
And Disassembly, and position it on the bed of an
arbor (or hydraulic) press. 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
piping hole and not damage the threads. Deburr
the hole from the inside of the seal liner after drill-
ing.
Slide the seal plate assembly over the impeller
shaft (18) and temporarily secure the seal plate to
