My swather has a Cummins motor in it. The PO put a new belt in it just before we bought it from him. The belt does not want to stay in the correct grooves. It is the correct belt, but it wants to jump one groove towards the engine. The crank pulley jumped a groove, but has come back already. The water pump pulley however stays a groove off. When I had the belt in the proper grooves it felt like the belt was trying to climb up the pulley. Everything on this looks to be original.
Any ideas?
