I googled it and got this, plus I know that on newer engines they are saying about .006 max. I wonder if using the impact to loosen the compensator nut shook the crank out of spec.? I will never know because I did not check the pinion first. Kind of doubt it though, being that far out one would think that stuff would be chewed up but it is not.

 

AI lies. Have you measured the I.D. of the pinion bushing in the cover? If it is in spec then I'd think things would be OK, but that is just my opinion.

 

I did not measure the bushing diameter but I can see that about 1/3rd of the pinion has a hot spot on it from running off center. The cam cover has damage on the gasket surface (I bought a puller) so that will be replaced. Too bad about this pinion issue because the rod bearings feel like there is not any play.
Cylinders are .010" over now and look pretty good so they will clean up with another .010" I think. If I can get away without over sizing them I will. I had all the precision tools to do this job but sold almost all of them when I retired. I do know that AI in not accurate, but it only knows what it knows. Imagine that running your life lol At least when I am done I will know what I have.

 

Oh, about that sprocket that has a lot of drag. LOL

You will need a tool to press the bearing on when every thing is setup.
