Description
Overview:
This replacement crankshaft restores smooth, reliable running in Stihl cut-off saw engines. Made from high-strength steel with precision-machined journals and threads, it transfers power from the piston to the flywheel and clutch while keeping rotational balance under heavy load. Engineered for Stihl TS410 and TS420 disc cutters, it is sized and finished for a direct fit in the crankcase with the correct bearing and seal locations. The accurate counterweight geometry helps reduce vibration, supporting cleaner cuts and longer service life of surrounding components. Use it to replace a worn, bent or damaged original shaft and bring your saw back to dependable performance on site or in the workshop. Replaces Stihl reference 4238 030 0400 where specified.
