Repair of crank pin of motorcycle

As a small editor who has specialized in the motorcycle crankshaft industry for more than ten years, I have long known that the production of crankshafts is a job that requires high technical accuracy, so how to repair crankshaft pins?
First of all, we analyze the fineness of the crankshaft pin. When the roundness and cylindricity errors of the crankshaft journal exceed 0.01~0.0125mm, the grinding process should be carried out on a special crankshaft pin grinder. Crankshaft pin radial runout, generally not more than 0.04~0.06mm. If it exceeds 0.10mm, it needs to be corrected.
Methods: cold pressure straightening method, knock method
Crack: magnetic flaw detection method, oil immersion tapping method.
The above two are just regular repair methods for motorcycle crankpins. If you have a better hair method, the editor is willing to communicate with you at any time.
