Repair of Cracks in the Crankshaft Journal

Chongqing Xiexiang Machinery Manufacturing Co., Ltd. specializes in the production and sale of crankshaft pins. It is a manufacturer, producer, and supplier of crankshaft pins based in Chongqing. From a highly professional standpoint, we analyze how cracks in crankshaft pins can be repaired. Cracks that occur in non‑load‑bearing areas or that do not propagate may be repaired. However, when cracks appear in load‑bearing regions such as the pin‑shoulder arm or the pin journal, the component must be replaced. Accordingly, our crankshaft pins are required to possess adequate strength and rigidity, while their journal surfaces must exhibit wear resistance, uniform operation, and excellent balance.

Repair of Motorcycle Crankshaft Pins

As an editor who has specialized in the motorcycle crankshaft industry for over a decade, I’ve long understood that crankshaft production demands extremely high levels of technical precision. So how should a crankpin be repaired? First, let’s examine the crankpin’s dimensional accuracy: when the roundness and cylindricity errors of the crank journal exceed 0.01–0.0125 mm, grinding must be performed on a dedicated crankpin grinder. The radial runout of the crankpin should generally not exceed 0.04–0.06 mm; if it exceeds 0.10 mm, corrective measures are required.
