To install the bearing frame cap, lightly apply a small bead of grease in the O-ring groove in the
bearing cap. The grease will keep the O-ring from falling out of its seat when the bearing cap is
bolted down. Install the bearing cap over the shaft and bolt down with the four supplied 3/8-16 UNC
bolts. Rotate the shaft to insure that the shaft spins freely. Make sure that the rotors on both ends of
the bearing frame are seated against the stator by pressing them together with hand pressure.

Secure the bearing frame on a
level plane before filling with oil.
Remove the breathing tube and
filling until the oil level is in the
middle of the bull’s eye in the
sight glass.
If the bearing frame is filled on an
uneven surface or tilted afterward,
oil will fill the labyrinth seal. Oil
will slowly leak out of the seal
port at the 6 o’clock position until
the labyrinth seal is fully purged.
