HI, guys have a question about my totally customized 12 valve oshkosh Tool Truck. Im haveing belt type sounds. I have been running the dayco tensionrs and belt for ten years and In my personal opionion they suck. But my question, I count 8 ribs on the belt and only seven on the pully? Really, from what I have read, ive seen 6 and 7 ribs with problems! What do I do?
