Can not say it often enough: check out http://www.mcmaster.com for parts
McMaster-Carr probably has what you need or want, even if you don't
know it yet, with almost a 1/2 million items listed, 75% of which is
in stock.

They have a branch in Ohio. I live north of Detroit, and if I order
around 11 p.m. tonight, it will be on my doorstep around 3 p.m.
tomorrow.  You may be able to find it cheaper some place else, but at
what cost in time and Googling around on the web?  You can order from
the McMaster-Carr website; they take charge cards or offer accounts.
(I do not work for them, nor have I ever.)

They have the link belts systems; leather belts, flat and round; all
styles of rubber and poly belting, flat and round; and also most
importantly, the tool for round leather belting, the clips for flat
belting, glue, and replacement belts for older machines.
