Product review (5 stars): Good belt, but installation was not-so-easy
Exactly the right belt, and seems to be reasonably sturdy. The original lasted for about 40 years - I hope this one lasts as long, although I doubt that I will care by the end of that time.

Installation was a bit tricky. If I followed their instructions, it would have been impossible - my hands are too fat to get into the small spaces around the lower rollers. So, instead, I installed the belt around the lower rollers first, and then put the drum back in place and worked the belt around the drum.
