My Scania's new clutch is slipping but there is no smell at all. Was slipping on and off. Then she's slipping and then all of a sudden she is riding smoothly, but a few days ago she was slipping a lot and had no usable power. I had the clutch and pressure plate removed, there's absolutely nothing wrong with it. May be you can suggest what the problem could be? This is puzzling me.
When clutch was checked was the throw-out bearing checked and replaced? It is usually a low cost item and best replaced at the same time as the clutch. While inspection of that part may look acceptable and it may seem to slip back and forth on the guide it is possible that it binds under load when clutch depressed and doe not full slide back.
