Purchase a pulley of the proper diameter and bore.
Any recommendations on where to go for one?
Local hardware for a start, motor shops and/or auto parts places and
other industrial distributors.
There's always the online route of McMaster-Carr, Grainger, et al, but
ordinary items like this shouldn't be any problem locally.
Rather than a flat side section on the spindle like most motors I've
seen, my motor has a notch cut out of the spindle in which a small
square metal peg was inserted.
That's typical keyed way -- more than likely 3/16". Key stock or precut
keys are a dime at the hardware store or may well come w/ the pulley.
Did the original motor run at the same rpm as the replacment?
....
... The replacement is a 1750rpm, and I'm pretty sure a machine of
this level wouldn't spin at the 3000rpm mark.
That's why I asked -- if you had a common 3450 rpm motor, I was betting
the original was likely 1725.
