I just finished putting a new timing belt on my 1995 Contour Zetec and had a questions about it. After putting everything back together and firing in up the belt immediatly move to the back side of the pulleys, at least at the top. It now rides the very back of the pulleys, maybe even hanging over 1/32" I first noticed this and disassembled and turned the belt so it was facing the other way, but noticed to difference. Is this normal?
