Which direct drive? I’m guessing it’s an elofty/boundmotor/esk8supply. Rattling was also an issue for me. There was some slack where the motor rests on the axle. I just used some brass shims to fill in the space and some steel epoxy 🤷. But you should open it up to see. You could just be missing something easy. Maybe provide photos or videos?
Also they sell adapters or you can 3D print one or find someone to do so.
It’s Torqueboards DD 75kv - sorry, thought i included that information. As far as i know these are hard if not impossible to open. Right - wrong?
Asked Dexter about the cost of the adapters. 140€, shipping included, is far more than I’d like to spend as long as i don’t know if the motors are prone to failing. Finding someone who can print might be a solution though.
I had that rattle on my TB DDs fresh out of the box, but only on one side. Like others have said above, just slide the motor can off the axle and wrap some tape around the axle (I needed only one layer of insulation tape) and slide the motor can back over it. The tape then takes up the slack and the rattle has gone. I agree the noise sounds like an expensive fault, but it is easily fixed. A metal shim would be better, but I didn’t have any to hand at the time and the rattle has still not come back even with the tape ‘fix’.
The noise does definitely not come from the motor mounts. I already tried lubricating through the seal, but the grinding and clicking stays.
I’d be ready for instructions on how to change the bearings. Would using c-clip-pliers to be able to remove the bearing seal be advisable? No idea if cleaning a bearing without being able to fully remove it from the can is even possible…
