So weird right? My mind almost could not comprehend it so I created a scenario where they welded it to the shaft because reasons So the shaft have a tapered shaft? So the straight bore pulley needs to be modified by a sleeve of sorts?

I do not own it yet. I have read om this forum people suggested the JK 563A1 so i asked CS about the shaft diameter/pulley inner diameter and got the response you cant remove the pulley. I guess 13 or 15 does not matter for me. Were the shafts in the motors you got tapered or straight?

Was the pulley easily removable? Was the shaft straight of tapered? Mind telling me where you found the smaller pulley? I have been in contact with college sewing and they told me the pulley is not removable.. very weird

I have recently been in contact with a supplier regarding this motor (JK-563A-1) and was told it is not possible to remove the pulley! As I read this thread I got confused. Did you find it easy to remove the pulley? Could you share the measurement for the inner diameter of the pulley? Was it straight of angeled?
