I have a bobcat T650 2014 with a Doosan D24 NAP engine the turbo failed at 1300 hrs. Has any else had this problem? The bobcat repair shop thinks it's because of fine dust particles. I've never seen any dust on the secondary air filter. I believe it was the bearing because i could wiggle the turbo around.Now the motor is toast,this is what their telling me. Does anyone have any thought's on this?
