I'm working on an 82162A printer (HP-IL for HP-41C) but this probably is the same internally as the 82143. There is a very thin round belt, looks like an o-ring, that runs from the motor to the platen drive worm gear. It is about .75" diameter and about .04" in width. This is a tough one to find. Diameter is not a problem, but the width is about half what most places seem to carry.
My question is this. Does anyone know how I could go about obtaining some? I need one for a printer I'm working on now because the existing one has dry rotted and will break soon, but I would expect that my other two printers will need this part soon.
I've looked several places that carry o-rings, but this width is just too thin. .07" seems to be the standard.
Thanks.
