شفة، بكرة عمود المحرك، مطحنة صغيرة

The lower flange seats onto the motor shaft pulley without any wobble, and the bore tolerance is spot-on for the X3 mill. Took me about ten minutes to swap out the old one, and it’s been running smooth ever since.

Fits perfectly on the X3 mill motor shaft and the replacement pulley went on without any issues. Exactly the OEM part I needed to get the timing belt back in working order.

Machined surfaces are clean and the bore alignment is spot-on, so the belt runs true without any wobble. Bolted right up in a few minutes and took up the old slop in the pulley. Exactly what the X3 needed.
