The flange seated perfectly on the motor shaft and locked the pulley in place without any wobble during a full run. It's a simple part but machined cleanly, and the fit on the X3 was exactly what I needed.

Installed this on my X3 mill's motor shaft and the timing belt pulley sits perfectly secure now. The flange does exactly what it's supposed to do for the drive system, no wobble or play. Solid little part for the price.

The fit on the X3 mill's motor shaft is spot on, so the timing belt pulley sits rock solid and there's no wobble during operation. It's a simple part, but it does exactly what it needs to keep the drive system running smoothly.
