With all the engine components apart (yes, I'm still working on that 22-36) and a warm day out I started cleaning up and thought I'd see how the crank mic'ed.
.003 out of round. Does anyone have tolerances for this? With .002 shims [looks like using about 6 {factory 11 from parts book} is about right] and (I think) .003 clearance specs, .003 oval seems rather high to me.
After a little polishing on one journal, it definitely had a few pits that won't come out - even if I have it ground .002, but few enough I doubt it's worth worry (let me know if I'm wrong though! :) ) . The rod [not originals but looked to be wore pretty similar] definitely got tight (so quick I didn't dare push it farther) about 45degrees from the loosest spot [after tightening it on 6 shims]; both the rod and shell behaved the same way on the shaft individually too.
This thing need a date with the shop, or are there options I'm overlooking?
