Sorry if I'm asking silly questions.
Just as a refresh, I bent my the shaft in my oil pump on my '47 A. I know what I did wrong, that's in the past now.
I did find a replacement but in the mean time I took my bent shaft and played with it on my press and more or less got it straightened out using a piece of plate glass and feeler gauges for reference (I don't have any v blocks).
Here's the deal. The replacement shaft it worn, .012 to be exact but is straight.
My original shaft isn't hardly worn at all, this engine really didn't have a log to hours on it. To bad the block cracked. Anyway, I was able to get it so a .002 feeler gauge wont pass under almost all of it. The exception is a 1 3/4" spot at the end (se photo below, the circled X is the high spot and the mark immediately to each side of the X are where the distance drops below .002") that's about .0035" (.004 drags) out at the highest point. I might be able to move it at bit more with the press but Im worried about hurting the surface. It slides into the housing and rotates with zero friction.
So which would you guys use? I'm kind of thinking either would work at this point. I'm leaning toward the original one that I fixed because of the lack of wear...
Thanks for bearing with me,
