We had our WD-45 crank turned and a rod repaired because we spun a bearing. more to the story but I am trying to find out the following.
Crank clearance I think the machine shop told us 0.0013 to 0.0043
Rod bearing clearance? they didn't tell us that one.
Crank end play?

Crank Clearance

Thank you

You need to be very concerned about two things: #1. correct positioning of the piston pins (so they don't cut a groove in the sleeves) and#2. proper shim stacks at each main bearing cap (should start out with .010" with a fresh crank and new bearings). If you don't get these two things right, all your work will be a waste of time and $$$$$$$$$$$.

Say chad plastiGauge isn't that tough to do, but if u have any doubt, there a couple of you tube video's where a guy is checking the crank etc, on a 350 Chevy, The one guy, Dave is pretty cool, explains everything, a perfect teacher.

Thanks I will watch it tonight when I get home. My brother has done it and is good with all the tolerance stuff he does calibration work for his job so that will help.
Thanks again!
