Now there is resolution-- 14 megapixels times 3 layers for the colors, I think. Is there a similar camera copy for the report showing the LP shaft that might show the condition of the splines? Not that that would mean anything after two hours of windmilling in an engine casing that could hardly have remained straight...

Am I looking at the inside of one of those large ball bearing thrust bearings as well? My looking around tells me that the entire assembly may be as large as 3-3/4" square (two rings and the included spherical balls), plus parts of the turbine made integral with the rings. I'd want to do some scaling off the pixels relative to the fan diameter, with a little perspective shortening thrown in, if I can locate a line parallel to the shaft-- well, the dolly should be, shouldn't it?

Anyway, the outer race of that bearing looks kinked as well. Could we call that bearing damage? I've found a reason to put bearing damage on the list of usual suspects, even if it had a fully functional oil supply. Tomorrow. Good work, bearfoil, in finding that picture. Does the raw file include any camera data such as lens focal length and size of its sensor chip (or camera model)?
