I thought I had a bent axle on my 41, got one from a FB guy and when it arrived I checked it out and it was good. I noticed how the key was installed, it was backwards from mine. Little light comes on, mine was in the wrong direction. The bottom of the key is tapered on one end to fit the taper in the key slot which was preventing the drum from going on all the way, the threads on my axle were screwed up any way so glad to get the replacement. been going to get the threads fixed but haven got around to it.
