im looking to rebuild my h22a4 motor. it needs a new crankshaft due to the crank bolt being stripped. im in need of information on how to check if a crankshaft is good and reusable without machining and polishing. thanks any info is greatly appreciated.

 

take it to a machine shop and have them check runout.

 

indeed...have them check out-of-round and taper of the journals as well.
