This is the 3rd time that I've had to take my ACE in because it was very hard to shift. Each time they replaced the ASM-Clutch, Oneway, and this time they said that the Primary Clutch Bearing was frozen. In addition to replacing the bearing they cleaned the clutches. I showed them the previous repair orders and asked why with only 2265 miles on the machine that the ASM-Clutch, oneway had to keep being replaced. The technician showed me how much fine dust was getting to the clutch through the intake duct. I have a good foam filter that I keep clean and oiled, but it still allows very fine dust to enter. The technician suggested that I cover the plastic intake cover with Frog Skin like Polaris has done on some of the newer models. Has anyone else tried this or had this kind of problem with your ASM-clutch, oneway, or your clutch bearing?
