The shaft for those motors is .125 inches if I remember correctly. Do the pulleys come with a bore this small? Do the bores have to be finished (reamed/drilled out)?
We buy our belts and pulleys from SDP-SI. The belt we used was a 9mm wide 3mm pitch GT2 belt. We had a bunch of 16T GT2 pulleys with 8mm bores as they were used in our drive gearbox, so we pressed in an insert that would reduce the bore to the correct diameter and then pressed the pulley with this insert onto the 775s. IIRC we just drilled the insert out to the correct diameter.
