Description
Overview:
This Genuine Stihl crankshaft is a direct replacement for the internal engine shaft in Stihl TS410 and TS420 disc cutters. Precision‐machined from robust steel alloy, it converts the piston's linear motion into smooth rotational drive, delivering reliable power to the cutting system. Built to handle high loads, heat, and vibration typical of cut‐off saw use, it helps maintain engine balance, performance, and service life. Supplied to match OEM specifications under MPN 4238 030 0400, it is suitable for routine rebuilds or repairs where the original crankshaft has worn, scored, or failed. Ideal for professional contractors, hire fleets, and maintenance teams, as well as DIY users maintaining their Stihl cutter, this part supports consistent starting, clean running, and dependable output in demanding site conditions.
