ralphw 1 Report post Posted December 31, 2010 Gavin The trapezoidal profile doesnt lend itself to that very well. The logical thing to do is to upgrade to the later pullies and belt. I have the same issue on my Sunbeam Lotus and will convert that in due course. I will never the less give your suggestion some thought, but at this time the modifications I would have to do to the belt with such a shallow tooth profile would increase the risk of belt jump and I really dont want to go down that route.
