How hard is it to lubricate a motor from a Super J. I know how to take it out, I'm just curious if I have to tear the entire thing down to lubricate it. Also if I do are all the fan blades keyed so I don't put them on in the wrong position?
. . . that will give you the info you need. This one is about the teardown:
and this one is about re-assembly:
However, don't use grease in the rear sleeve bearing. It has a large felt wick to hold non-detergent motor oil. That is the only proper lubricant for this bearing, and if it doesn't run dry, it will outlast the rest of the motor. Otherwise the videos are good IMO.
