3406 b-model? What are the signs of a turbo going bad?
Is there an upgrade turbo ?
Thanks!

 

When I have had a turbo go out, I don't remember any warning. They just go and there is smoke everywhere. It is usually the bearings that have a problem, according to my local CAT dealer. I had one that lost some of the blades off the fan, but it might have still been the bearings. If you have a pressure gauge for your turbo, that might give you some warning. It has been a while since I have had a problem with a turbo. Mine was a 3406E. I have lost them on a Detroit. The symptoms were the same. If I were you, I would check with a local CAT dealer and see what they say. You may also check with Truckpro or Fleetpride. Some of them have good mechanics (or former mechanics) that work there.

 

Thanks gman!

 

sometimes they'll moan.
