Mopar Performance P3690715 Shaft Diameter

Are the scoring marks even all around, or are they deeper/more concentrated on one side? If more on one side, that probably says something is not concentric on the shaft or hex. If even scoring all around, then it is either the bushing off-center or just a tight fit in that lower hole in the block.

How is the mesh of the gear with the cam gear?

Thanks, I did have a look at this yesterday, the scoring is fairly even and the mesh with the cam gear is good. Regardless, I’ll have a look at the shaft on some v blocks this week to check straightness. The shaft is tough to install and remove even with no oil pump or cam in place so I’m still thinking it’s just a tight fit in that lower hole, appreciate your help.
