e) During installation, simply discard any O-ring
material pinched or sheared by the bore. Make
sure the face is perpendicular to the shaft.
f) Once a Bearing Gard™ is in place you may
remove and plug the bearing housing vent.
Bearing Gard™ is self-venting and will not
allow pressure build up in the housing.
Plugging the bearing housing vent will reduce
the entry of contamination into the housing.
g) Refill the bearing housing to the correct oil
level.
