Chevrolet Repair: crank, upper shells, dial indicator

Question
How to tell if CRANK is bent

Answer
Hi Raye,
The only way I know is to have it checked in a crank machine, although if all the rods and caps are off, and you can rotate it in the main journals, a dial indicator could be used to measure runout.
You would need all the main bearing upper shells removed except the front and rear ones.
