Thanks for finding that old thread, Richard.

I measured a spare BTR 51050 belt I have and surely enough it measures 53 inches on the inside. Combined with approx. 2 mm of wear (not stretching - thanks Richard) it obviously is now over size.

Have searched the internet and a B52 v-belt is an off the shelf item, used in many applications. I will call my local supplier tomorrow, surely this is a faster and cheaper option than buying from the States. But thanks for the suggestion, Lauren.

Will let you know how it all works out - thanks for now!
