@Hannes to be clear though i have grub screws in the middle of the pulley and the rim. When removing use a good quality allen wrench or they strip out.

I believe TorqueBoards recently changed to this version of motor pulley. I’ve received both versions from them. With the previous version the two screws didn’t protrude. Shouldn’t matter though as others have said if you use grub screws and locktite
careful pulling it off the shaft though its very easy to damage
