Description
Overview:
This Roller Chain for Stihl RM 545.0 VR Mower is a genuine Stihl/Viking drive component designed to transmit power reliably within the mower's drive system. Made from hardened steel for strength and wear resistance, it is built to handle regular mowing conditions and maintain smooth self-propulsion. Engineered for a precise fit on models such as the RM 545.0 VR and MB 545.1 VR, it helps keep cutting speed steady and the machine responsive. Supplied to OEM specification under OEM No. 6340 780 0601 (MPN 63407800601), it replaces a stretched or damaged chain to restore consistent performance. Light surface oxidation from storage may be present and is normal; it does not affect function once the chain is lubricated and in service.
