Help with Novak SS13.5 dissassembly
 

This probably sounds stupid, but I need to sort this out so if anyone could give some insight on this it would be greatly appreciated and I know you guys are the brushless gurus so hopefully you can help.

Ok here goes, I have a Novak ss13.5 system for my 1/10 pan car, I picked the motor system up used and it runs great, however one of the mounting holes is stripped out, of course its on of the ones I need :whip: . Anyway there are multiple different mounting holes on the end bell, and three screws that bolt it on so I thought (always a bad thing) that I would just rotate undo the end bell and rotate it to a different orientation so I could get a new mounting hole. Well I did this and now when I spin the motor by hand its very notchy, much like my Neu or my Medusa, like you can feel the poles on it, it was never like this before, it would spin very smoothly by hand. Did I do something wrong, should I have not tried to clock that peice without changing endbell orientation as well?

Anybody got any insight on this?

According to the Novak website what I did shouldn't be a problem, there are actually instructions on their on how to clean the motor and their description is exactly what I did so I really don't understand why the motor is notchy now. Could it be that I tightened the screws to tight?

I've torn down several Novak motors,and never had a problem.The only thing I wonder about is did you get your shims and spacers in right?Is it possible one of the shims fell into the motor while you were disassembling/assembling?The endbell position should not have an effect,that I've noticed,anyway.

I suppose the there is the possibility a shim could have got inside, but I assume the shims go on the rotor shaft and I didnt remove the rotor and I have also run the motor and it seems to run OK, Im thinking that maybe I have the end bell too tight and its clamping on the rotor too hard and what im feeling is the bearing being loaded too hard, perhaps I need to actually remove a shim?
