4. After ensuring that the cap screws securing the retaining seal cap to the overhung load
adapter remain at 25 ft. lbs., check the gap between the retaining seal cap and the adapter
housing between cap screws using a feeler gauge. This gap should be between 0.0015”
and 0.010”.
5. Remove the retaining seal cap. To assist in
removal, two cap screws may be installed into the
push off holes in the retaining seal cap.
6. If a minimum gap of 0.0015” did not exist
between the retaining seal cap and bearing
housing inspect the bearing for signs of
“creeping”. If any signs of bearing creep have
been detected, the retaining seal cap should be
replaced.
NOTE: When the bearing is trying to “creep” out of its
normal location and pushing out on the retaining seal
cap, there will be signs of wear on the outer rim of the
bearing where it comes into contact with the retaining
seal cap.

Push off holes in the retaining seal cap should be aligned with counter bore holes in housing to
prevent damage to housing during future maintenance. Secure in place using existing .31” socket head
cap screws and loctite 271. Torque to 25 ft. lbs.
11. Repeat step #4 to assure a minimum gap of 0.0015” and a maximum gap of 0.010” remains.
