Some radial play is normal, as long as it is not the outer ring being loose in the housing. It is felt well in the prop because the bearings in the 58 engine are not very far apart. No radial play is what I would be worried about. As soon as a new or overhauled engine runs, it should become ''loose''.
I am not talking of excessive play.
Agreed, determining what is normal and what is excessive is the hard part here. Pe, do you have any numbers and measuring suggestions?
