![]() ![]() Now that i know what I'm doing it'll go way fasterĪlso kind of amazed that all of the motor torque gets transferred through that thing with the pawls, especially since it's so buried in the motor - seems like that mechanism could have been external to the motor. I also asked iZip if they sold parts, I'd feel better about it if they could sell me that whole gear assembly and I could just replace it. There is one video of someone disassembling one, although not as far as I went. I was surprised not to find any shop manuals or parts diagrams on the net - does anyone know where I might find one? I wrote to iZip, waiting to hear back, but this really should be a thing they just make available. I also worry the housing that bearing presses into may have already been damaged (there were some metal shards when I took it apart and I think I know where they broke off from) which may have been the source of the problem, so maybe the whole thing will just break again.Īnyways, not really how I wanted to spend 10 (!) hours on a Saturday. I reassembled the whole thing and rode around the block and it works! Although it's noisier than it used to be, I'm not 100% sure I put it back together perfectly (there were a couple washers I should have paid more attention to). But, I put the pawls back (which was tricky) and confirmed that it would now "lock up" in one direction so the gears would turn together. I wish I'd have gone a little slower taking it apart to get a good look at the state of it. So, I took that all apart and you can see a bunch of pawls fell out. If I turned the big gear by hand, the little gear that drives the crank wasn't turning. I confirmed that seemed to be the problem, the motor was running but not providing any power. The part with the pawls only engages in one direction when it's engaged both gears turn together, when it's not they just spin freely. Sorry I don't have a good picture of the thing assembled, but roughly the thing with all the pawls goes around the shaft part, then that whole thing goes inside the bigger gear, then the small gear also gets mounted on the shaft. I did some tweeting about the disassembly if you want to follow along but the important part is probably what's in the picture - that transfers power from the motor to the crank. I suspect that the issue is probably related to the hall effect sensors or wiring and I'm wondering if there is anything else I can test.ĭoes anyone know the pinout of the hall effect sensors? It's a 10-pin harness (2 large, 8 small).Hey all, my e3 Dash mysteriously stopped boosting last week, and Saturday I tried to diagnose/repair it (successfully for now). There isn't any visible tearing of the hub motor wire, but the bundle does have a slight kink in the middle that could indicate it was damaged. Because of this, I have focused on that connection and made sure it looks good, is firmly seated, and cleaned with electrical contact cleaner. That seemed to resolve itself when I unplugged and plugged back in the cable harness on the chainstay. There was a short period when I couldn't get it to show the motor speed and it would throw an E5 (motor speed sensor error) when applying throttle. I can only get it to run the motor once every few attempts of twisting the throttle while pedaling. The motor sound lasts from a fraction of a second to a couple of seconds and then cuts out. If I get it into a speed range where it is showing a speed and give it throttle while pedaling, I can sometimes hear it give a momentary burst of motor torque. Below this speed, the throttle doesn't do anything. The issue I'm experiencing is that it doesn't start to detect or display wheel speed until about 10-15 mph. The connections to the controller and to the motor look ok and have been cleaned and reseated. The battery is fine and all of the diagnostics look good in terms of cadence sensing, throttle/motor command, brake lever values. This is a Currie / Tranzx hub motor system, 48V, 500W. I was given a 2015 iZip E3 Dash that is having some issues with the wheel speed sensing and possibly the motor. ![]()
