Description
Overview:
This Belt Pulley is a genuine Stihl drive component for professional disc cutters, engineered for smooth, efficient power transfer through a Poly V-belt. Built from durable metal with a grooved multi‐rib profile, it supports reliable transmission from the engine to the cutting wheel under tough site conditions. It is the correct OEM match for Stihl TS420 (OEM No. 4238 760 8505) and also suits models such as the TS500i-A within the same family. Precision manufacture helps maintain belt tracking and reduces slip, heat build‐up, and premature belt wear. As a direct replacement part, it restores drive performance on machines that have suffered pulley wear, corrosion, or damage, helping your cutter run true and cut consistently.
