Bill, glad you were able to safely get it changed out. Question: do the new turbo blades look like the old one? IOW do the blades have the same split you mentioned above? Also looking at your picture again the center nut appears to have some damage.
Just trying to think this through, as I mentioned above the mechanic who changed mine listened to the sound of the turbo and determined it was bad. My hearing is not great and I couldn't detect any difference in sound but from other symptoms was sure my turbo was going out. My blades were good but the bearings were going bad.
Were you able to find the pieces and remove them?

Forest,
Gordon’s got a Detroit so his turbo will be different than mine. I think my “split” blades are the way it came from factory. I did not end up having a bad turbo...it was the hydraulic fan running at full speed making the noise.
From what I can tell from Gordon’s picture, it looks like he has a more tradition style turbo.

Oops, I misread Gordon's post thinking it was you Bill.
Still scary to see those pieces in the housing.

The cause is not known to me! I suspect something had worked on the ends of the blades. Discovered while changing air filter, from PO’s poor care maybe.

Whatever the cause, I’m lucky to have been able to fix it roadside. I suspect a blade broke to start with then the rest is history. I do use the jake brake down shifting through the gears but don’t get nuts downshifting with high rpms. Usually target 1500 rpm before downshifting to the next lower. Stopping preceded the breakage, whether they are related is an unknown.

I should have stated the discovery of the blade ends was four years ago. No previous signs of anything wrong after using it with the damage that long. It probably was the eventual demise of the compressor section. Interesting the turbine was still spinning and no oil leaking, darn compressor shaft broke at the large end of the wheel. Edith heard it and said “something just broke”.
