My wife complained last week that her elliptical trainer was not running smoothly. I tore it down tonight. It is basically a big crank and a flywheel. There is a v-groove belt that drives the flywheel. The belt was up on the shoulder of the crank and was rubbing a bracket on the side of the flywheel. I recentered it and it is running ok now but the belt is chewed up. I want to replace it. The replacement for her model machine costs 20 bucks. Is there a way to identify size, etc for the belt to buy a cheap replacement, other than measuring? It has 'MicroV 475J" printed on it. I googled that but came up with bupkus.

MicroV belts are made by Gates Corp. Perhaps going here or contacting them directly will get you the specs you need to look for something comparable, but less costly. -
all the info you need is on the belt. you need a "J" profile belt, 475 length. you'll need to count the number of ribs. Gates doesn't list a 475 length so it might be OEM supplied parts only. a local "bearing" shop or industrial supplier should be able to help. Motion Industries is a nationwide specialist in this kind of stuff.Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas EdisonComment

Thanks fellas. I went and looked at the belt again and it is actually a 47J5. Looking at the gates site I don't see the belt listed, but at least now I know it is J profile, 5 ribs and length is 47. Now I am wondering why it moved in the first place, unless the frame racks or something when you are using it. I put a straight edge across the flywheel and crank and they are in line.David

Wouldn't worry about why it moved unless the new belt moves also. If it does, then one likely culprit would be bearings with some runout.Comment
