I am cleaning up my Sheldon horizontal mill and am not sure what to lube the motor bearings with. Both end bells are plugged with plug screws, so I'm not sure if they need grease or oil. Looking down in them one is clean as a whistle with no signs of grease. The other side has a small amount of grease visible but not much. Access to the motor is tight, so I want to lube it good before I reinstall the motor. I'd also like to install either zerks or oil cups depending. I think it's around 1950 vintage.
Any thoughts?
It's a Marathon 1hp 3 phase motor
Thanks
