M5040 Turbo Squeal when hot

interesting that Kubota changed the design. I don't remember but mine was bought new in 2010 or 11?

I'm wishing now that I had the earlier version. I am hoping that it is something external like the wastegate linkage. There are no other potential noisemakers in the area of the turbo and it is a noise unlike any I have heard a machine make. Think screech owl or something.

Screech owl! That would make you pay attention. So can you slip the intake hose off and look at the turbo shaft? I usually check mine once in a while just to see if the fins have been rubbing on the housing. You can also then put your finger on the end of the shaft and wiggle it sideways to check for how much play there is in the turbo bearings.

That is worth doing. Thanks! - Lee

Well I am quite happily wrong about my turbo noise. It is not a turbo, it is not a belt, but it is the A/C clutch that is squealing when it engages. I can deal with that. Thanks for all the input. Oh, and @pmsmechanic the turbo impeller and shaft look happy. That was educational.
