I have a 10kw diesel that has the belt issue. 500 hours is the max I have gotten. O-no dealer says it should 1000. Have used O-nos way overpriced belt and Gates and Dayco- very similar results. I believe the belts fail because the air flows thru the radiator then over the hot engine before it reaches the belt. I think this very hot air flowing over the belt causes the failures. I have installed an extra fan blowing air into the radiator to hopefully reduce the temperature of the air flowing across the belt.
