A local machine shop (Job shop type, not production machining) can change
bearings easily, or find someone who does it for a hobby (hey, they are
really small job shop machine shops).  However, don't be shocked if it
costs more than a new pulley.  Figure shop rates of $45/hr and UP, with a
minimum of an hour, plus parts. (the guy with a garage shop might do it
for less)
