So I got my crank back from a different machine shop this time, and they turned it down .010 on the mains to clean up my out of roundness. I rotated it several rotations on an V-block and had no deviation. My new oversized bearing came in yesterday, and I’m checking clearances now. I plastigauged the middle bearing and I have what looks to be .0018 of clearance. Is this acceptable? Here is the pics to double check me.
My rods were right at .001, so I’m good there. Attached thumbnail(s)

I would have the machine shop do the measurements. They have measuring tools that are much better than plastigauge.
You really want to measure at every bearing. Just measuring one and hoping the others are the same can get you in trouble. |
