    Troubleshoot Mac Motor

    For now I'll just buy a new wheel so the bike'll be rideable ... the rest of it ... :oops: One final question before wrapping things up ... when I pulled the clutch off, I noticed that one of the gears' bearing was really wobbly loose ... is that normal? I mean, does that happen alot? Second...

    Voila! Done. I didn't need a puller after all. 3 - 4mm X 70mm bolts pushed the magnet off the stator and I was miffed at myself for not being more careful. Lesson learned.

    Troubleshoot Mac Motor

    At that point I figured there was no reason to be gentle with it, so I hacked off the wires started disassembly of the wires and all that. A little knowledge can go a long way. Because I found what I had overlooked in my eagerness for the quick fix ... the all important circlip.

    That didn't work and I end up with this: While applying moderate pressure, there was also some awful cracking sounds and the shaft got woobly loose in the bearing.

    Troubleshoot Mac Motor

    Well, things didn't work out as I had hoped. Pretty sure all I've got left to hang on the wall of shame is a trophy of what NOT to do. I thought I'd combine parts of the Grin and spinningmagnets guides. Everyone, don't be like me. Spinningmagnets is the only way (certainly for my motor). I've...

    Troubleshoot Mac Motor

    On my way to work today I took my multimeter, tested continuity and all is good, so ... it looks like I'll be pulling it apart tomorrow or next. Cheers everyone that's helped.

    I took a closer look at it; turns out it was just a bad photo....as I think this one shows. Thanks y'all for the help. This is a great board. I appreciate everyone's help so far. I'll get to tearing it apart over the weekend. I took a look at it today and decided I needed more time to tear it...

    Troubleshoot Mac Motor

    I gave each wire a gentle tug, but they seem to be well attached. Tomorrow, when the wife is out, I'll 'borrow' her hairdryer and pull the PCB off the motor; that might reveal something more. Thanks y'all!

    Troubleshoot Mac Motor

    I'm mechanically inclined, but just haven't done a lot of research about this problem ... so I apologize if I ask any 'simple' questions. When you say PBC, do you mean the green part?

    Troubleshoot Mac Motor

    I did that today (took it apart), but left my phone in the car ... and my wife's out all day. I'll post a couple of pics later. I didn't SEE anything broken or unsoldered, but sounds like you have more experience than me and know where to look.

    Troubleshoot Mac Motor

    A day later ... After testing, it was the yellow wire that indicated a problem. Following the testing on Grin, the multimeter doesn't change at all....it's stuck on 5.00. So, I guess the next question is: where do I get the right hall sensor? Thanks.

    Thanks molybdenum for the link. Tons of info. And thanks to motomech .... I'm picking up a multimeter today and should know by nightfall what I'm looking at. Cheers

    Troubleshoot Mac Motor

    I have a mac motor that I bought years ago from Paul at EM3EV. Like many people I've put thousands of trouble-free miles on it. Right up to last week. I hit a curb, that I've hit hundreds of times before (without problem), and the motor stopped working. I have a CA which showing the PAS speed...
