Okay so I am rebuilding a motor and I'm trying to find what size bearings I have or if I could just measure the crank journals with a dial caliper. Does any one know what the stock size of the crank journals are?

The bearings have a sign like (lh) and say H30S
0170A

Please help

Not going to grind the crank and match the bearings accordingly?

well its just getting a basic rebuild and the bearings in it still had easily had under 50k on them I am fairly sure the motor has be gone through before be I just wanted to be sure. Plus the crank is in perfect condition not even the slightest scratch.

easiest way is to plastiguage to see if the clearances are correct

Plasigauge won't tell you if you have an out of round oblonged journals. I highly suggest you have a machine shop look at both the crank and the block.

Why are you tearing apart the motor after only 50k?

Well the motor was a junkyard motor and I wanted to tear it apart to be sure it was good. Also I took dial calipers to it all the way around each journal and the measurement didn't change.

I found the measurements of the standard journals and I was with in thousands of the standard

Never mind I measured bearing thickness, journals, bore and they're all STD and all with in round. Now I just need a speedy sleeve on the rear end of the crank
