It should, it is the headstock pulley that has an odd sized bore, 13/16". The motor pulley is a standard bore and should be matched to whatever size your motor shaft is. Typically, they are either 1/2" or 5/8" in diameter.

I am away from 'home' in Gatlingburg, TN. this week, but I thought the pulleys were 2", 3", 4". The Grainger one has smaller sized mid and large step pulley.

Are the ss version larger(actually 3",4")?

I am never sure what folks are wanting to accomplish speed wise. The following is Grainger's 2x3x4 http://www.grainger.com/Grainger/wwg/search.shtml?searchQuery=4X559&op=search&Ntt=4X559&N=0&sst=subset

THAT is more what I would have expected as a replacement for a '10' motor pulley. IMHO one needs to maintain identical cone pulleys so as to NOT affect the tension when the belt is relocated.

Again, you never know what speed(s) people are trying to achieve. I have seen these machines with 3450 rpm motors. I have toyed with setting one up as a shaper with the higher speed motor. Anyway in theory, tension should be released before moving the belt position and then retensioned after.

Upon more thought(on my part) you be correct re tensioning. My 'thinking' was more towards drill presses with 5-6 steps which have 'automatic tensioning'.
