I discovered that modern V belts don't always match well with the older type pullies. There is a standard for V belts that's been around many years , the "B" type is commonly seen in older machinery.

My series 1 Land Rover is always a problem, finding the correct belt . I have fitted a modern belt that functions but somehow the modern belts don't quite fit correctly, the new belt makes a squeeling sound , as if something is rubbing . I believe the series 1 club in the UK had a special batch of belts made .

Yes I agree with the comments, that C8 belt isn't sitting as it should be , the profile is too narrow or the "v" angle isn't correct.
