I have an 08 650 H1 with 1037 miles on it. I just replaced the main crank bearing. It showed no signs of wear or heat. I've always taken great care with the oil and ect. It appears as the bearing cage(holds the ***** in place) just came off. Has anyone else had this problem as Artic Cat would not cover it as the machine was out of warranty?

 

No i have not seen this but it was a bad bearing or casting in the steel. did you have cat care they are really good.
