propel endevor F.O.C. 3.0 sensorles

[Grzeny]

Hi everyone,
After about 1.5k km, a bearing in my motor (on the Hall sensor side) failed. I don’t see any way to replace this bearing without destroying the Hall sensor. Is it a good idea to completely remove the sensors in both motors, replace the bearings, and set the remote to “sensorless”?
I’m referring to these motors: https://www.ridepropel.com/electric-skateboard/endeavor-6374-motor/
Does anyone even know the size of this bearing?

I haven’t had that specific motor before, but perhaps this could be helpful?

Assembling a BLDC motor [serious]

How I assemble a BLDC motor. Starting with a stator, a rotor, three bearings, a circlip, a circlip tool, some spacers, oil, three M4x8 bolts and a wrench for them, a hammer, an 8mm shoulder bolt, a dry washcloth, a motor pulley, a motor mount plate, maybe a tiny piece of griptape/sandpaper, and maybe a skateboard wheel bearing spacer: First, I start with the stator [20200629_011846] bolt it to a mount plate [20200629_011955] grab a shoulder bolt or something else [20200629_013245] I l…

Okay, guys, sorry for yesterday’s panic.

I found a solution

The Hall sensors are not glued to the stator

and the entire board is mounted +/- on the bearing. After knocking out the bearing on the other side, everything fell apart nicely.

bearing sizes:

6000RS x1 (10x26x8) & 6800ZZ x1 (10x19x5)

Sorry for the off-topic, but I also checked that:
After disconnecting the sensors and switching F.O.C. 3.0 to the “sensorless” option, the board behaves quite well (after 10 km, there were no problems with temperature or brakes).
