Sorry if this is the wrong place to post this.. only section I could find pertaining to motors.
I have a Westinghouse 3/4 HP motor on my lathe. I had it apart to redo the wiring and decided to look at the bearings. It has a single row ball bearing type on each end. It is sealed on the armature side, but the outer side is open and slides into a round pocket a little wider than the width of the bearing . On the outside on each end cover of the motor is a single screw in plug with a channel angled toward the round pocket. Even If I did pump grease into the hole, there would be nowhere for the pressure to go, and might pop out the seal. When I filled the pocket with grease and pushed the end cover on the motor, grease was forced out of the open hole.. maybe this was the right procedure?
OR..
I am wondering if I am suppose to use some kind of oil instead of grease?? Seems oil would leak out.. any thoughts?
Another interesting note.. when the motor is mounted, the plugs are facing downward.
