Two years ago my garage burnt. I had a factory steel crank that was in the fire. I have been told that I could still use the crank. And, I have been told that it is no good. I did take it to the machine shop and had it turned .10 under and was told it was straight. So, the question is: use or not use. Thanks, Mansfield

Use it, unless the fire was directly on it. When a building burns, it usually falls in or down and insulates the floor from direct heat. If the crank has not turned colors then it has not been very hot. BIGG C

Pack in dry ice in a very well insulated container and leave it for at least a week or two. This will re-align the molecules in the steel and give it a case-hardening. It has to warm-up by itself, you can't freeze it and then unpack it in a day or two. This works great with used, re-ground cranks. Good Luck...Dan

A good friend of mine lost his shop to a fire this past spring. He is an auto mechanic (since Jesus was a baby) and has had his own shop for forever also. Many of the parts he had lying on or about the floor made it through the fire. Other stuff not. My race car partner had a complete rear end assembly for his chebby truck in the shop on the floor and he thought that it wouldn't be any good. Checked it out and it IS good. As BIGG C said, if it didn't turn colors then the heat probably didn't get it bad enough. I would only use it in a cheap motor though. Metal and molecules are funny creatures. Nodular iron vs. billet steel heat up different and I don't know that I would trust it too much. It's your dollar. As stockcar5 said, it's heat treated now!

Dry ice? Never heard of that one. Sounds interesting though!

I will try the dry ice. I was wanting to use it in a spare motor. I will put her together and let her fly. Thanks, Mansfield
