Messuring a crankshaft

[Rabbi]

Hello i just picked up a used crankshaft in excellent shape, And im unsure what size bearings im gonna need.

How do i go about messuring the bearing surfaces to tell if the crank has been machined at all?


Thanks

You need a micrometer, I believe a 2-3. Just take it to a machine shop, they will do it, it takes 5 min and prob wont charge.

also you will have to know the std specs for it.
and then do a little math after it has been mic'ed
