Crankshaft repair

joespanova · 06-20-2014, 05:11 PM

Anyone have any suggestions .
I have 1 journal that may need repair , however , this journal is hard chromed , as they all are. Years ago I had Crankshaft Specialist in Memphis do some work after a rod break. They did very nice work ......then. From what I'm reading on line NOW , they / he is an untrustworthy ripoff. I am only repeating what you can see for yourself with a Google search.
So , what happened to them?
And who now is doing hard chrome repairs?

Dougy Rowe turned into a bad guy, Callies and Bullet cams offer crank repair as well.

It really is not necessary to chrome a crankshaft these days. Chroming was commonly done when it was much harder and more expensive to nitride a crankshaft, only big corporations had access to it. When you grind a crankshaft, especially if you have done a repair, once you grind it very much, you grind through the nitriding, and in some cases, the heat treating. You end up with a journal surface that is not real hard, it won't get quite as slick, and it will be more vulnerable to debris and sticking. You don't want the entire crankshaft hard all the way through, but you really need to get the surface hard. Chroming a crank merely makes the surface hard, and there is a risk of hydrogen embrittlement. These days, most good crankshaft repair businesses have access to both heat treating and nitriding.
