What kind of tolerance does a racing crankshaft have?
A racing crankshaft isn’t necessarily a disposable component – As seen in Drag Racing Scene magazine. Racing cranks adhere to the tightest tolerances. Typically, the machined surfaces on today’s racing crankshafts are held to a .0003-inch (or better) tolerance right out of the manufacturer’s box.
What do you need to know about welding a crankshaft?
The completed weld shows the careful welding of both the bearing face and radiused corners. Note the heat colorization on the crank surrounding the weld. Before the welding process, the crankshaft surfaces to be welded are lightly ground to remove any foreign materials, like bearing material, embedded in the crank.
Do you heat the crankshaft before or after a repair?
“Our experience goes into any heating of the crankshaft needed before and/or after the repair process,” Darner points out. “Depending on the crankshaft material and what kind of heat treating it had as a new product, we follow any pre- or post-oven time to hold the strength it had from its manufacturer.”

Can a crack be repaired on an Ohio crankshaft?
General wear of the crankshaft surfaces can go outside of tolerable dimensions, and cracks or bending can take place. A repaired crank is then machined and re-ground in the same high-tech machinery used to create Ohio Crankshaft’s new product lines.
