use at higher operating temperatures.
Inspect the pinion shaft (35) for distortion, nicks,
scratches, or damage to the shaft keyway. Dress
small nicks or burrs with a fine file or emery cloth. If
excessive wear exists or the shaft is defective, refer
to GEARBOX DISASSEMBLY and replace the
shaft.
Lubricate the stationary seat O-ring with light oil
and install it in the stationary seat. Use thumb pres-
sure to press this subassembly into the pump cas-
ing until fully seated. Be careful not to damage the
seal face. After installation, wipe the seal face in a
concentric pattern with a clean, lint-free cloth to re-
move any fingerprints.
NOTE
It is recommended that a tapered sleeve (see Fig-
ure 3) be installed over the shaft keyway to ease in-
stallation of the rotating portion of the seal. This tool
can be made from steel tubing or black pipe.
