Troy-Bilt variable speed drive problem

[Rivets]

If you bent any part of the variable pulley assembly you will probably have to replace the entire assembly. The center sheave may be bent, not allowing it to travel smoothly and pinching one or both belts.

It's not the variable pulley that's bent, it's the engine pulley. The variable pulley seems to be fine. It moves smoothly.

This site has belt information you may find interesting - including clutching / wrapped.

I replaced the engine pulley, but it didn't make a damn bit of difference. (It was a bitch getting that thing off of there too!) So I guess I'm back to the belt.

Edit, just read the reviews of the belt I got. Lots of people have the same problem I did so I'd say it's definately the belt. Off to buy an OEM belt.

Thanks for the update. I also tend to buy from Amazon and not to consider anything on a mower to be "precision part". In my case, it turn out to be ok with a non-OEM kevlar belt, but certainly will keep that in mind next time.

A belt may not be a precision part, but different manufacturers use different belt angles. Using the wrong belt will result in slipping and faster wear.
