Hello again The drive pullys were actually 6 1/2 inch diameter on my machine. I spoke with a couple of dealers and ended up with a Megadyne Varisect make belt 28mm wide 8mm deep by 800mm long. It wasn't too bad to fit and works fine with a much smoother drive. Many thanks again for the pointers Peter

Hello

Many thanks for your reply. Have used the info to order a replacement.
