wstuart Posted May 29, 2022 Share Posted May 29, 2022 Just wondering if anyone could help me with this. Issue #1. Occasional motor knocking noise Here is a video by Ray Rokni that shows a knocking sound that he says is caused by "mis aligned magnets" he is able to make the sound come and go. I have an identical knocking sound that forms about every third time I ride this wheel, but i can't make it go away. I just have to let the wheel sit for a week, and then the sound won't be there for n the first 2-3 riders. What else can I do about this? Is this dangerous?? Issue 2: i have play between the wheel and chassis front to back. I can make the chassis rotate front to back a 2mm before the wheel spins. This feels just like the play I get in my MSP HT with the axel bolt is loose - but this doesn't have an axle bolt - it's hollow!! What could cause this??

Could Imagine the Play is a little bit to much somewhere in the Suspension assembly Edited May 29, 2022 by onkeldanuel Quote Link to comment Share on other sites More sharing options...
EMA Posted May 29, 2022 Share Posted May 29, 2022 it's not dangerous, it's caused by misaligned bearings, the root cause is the motor side cover to not hold bearings well. it's fixable but you need to disassemble the motor and put some spacers inside, it's a workaround but i've done it multiple times and it works 3 Quote Link to comment Share on other sites More sharing options...
alcatraz Posted May 29, 2022 Share Posted May 29, 2022 With larger bearings there's probably also a bit more play in them. Also they might not need to be pressed all the way in. If there's a loose fit use a little retaining compound. Quote Link to comment Share on other sites More sharing options...
onkeldanuel Posted May 29, 2022 Share Posted May 29, 2022 Yeah agree the combination of the knocking Sound and the Play seems to really be somewhat loose Bearing seating Quote Link to comment Share on other sites More sharing options...
wstuart Posted May 29, 2022 Author Share Posted May 29, 2022 Ah I see. Well glad to hear it's not dangerous. I'll see if I can live with it Quote Link to comment Share on other sites More sharing options...
Whalesmash Posted May 29, 2022 Share Posted May 29, 2022 When my wheel makes that knocking sound, I just put the wheel on its side and shove the tire/motor up or down to "reseat" the bearing. Kinda janky way of reseating, but it has made the noise go away and it hasn't come back for months. As for the front to back play, my EX does the same thing. It's a bit annoying but other than that, it has not caused any long standing issues. 1 Quote Link to comment Share on other sites More sharing options...

It's my favorite wheel! Quote Link to comment Share on other sites More sharing options...

I might need to take it apart and use some retaing compound on the bearing. I wonder if I can find new motor bearings for this wheel?

I didnt have to put any crazy amount of force on it, I just laid the wheel on its side and leaned my body weight onto the tire. Think about as much force as someone doing CPR or something like that. I do know that others have done bearing replacements, but I don't know where or what number/size a correct replacement would be. Quote Link to comment Share on other sites More sharing options...
onkeldanuel Posted June 6, 2022 Share Posted June 6, 2022 Its 6832 (61832) bearings Quote Link to comment Share on other sites More sharing options...
