Re: Chrome the crank journals ?
I've had several shafts repaired with hard chrome but they were power transmission type shafts that had a small journal that needed built back to specs to keep the tapered roller races a tight fit. A crankshaft is a whole nother ball game. I've heard all sorts of stories about welding up journals to get long strokes and hard chroming others but it is a gamble. The shafts I had repaired were $6500 new and the repairs ran about $1500 so it was worth it on those. On the old Pratt & Whitney radial engines they used to hard chrome the link rod bushings back to specs but they wouldn't touch the master journals.
