5. Dispose of cardboard washer and recheck seal
face to be sure it is free of dirt, foreign particles,
scratches and grease.
6. Inspect shaft to be sure it is free of nicks and
scratches.

9. Slide rotating seal member (carbon face first) onto
shaft until rubber drive ring hits shaft shoulder.
NOTICE: Be sure not to nick or scratch carbon face of
seal when passing it over threaded shaft end or shaft
shoulder. The carbon surface must remain clean or
