Description
Overview:
The Pulley Crankshaft (OEM ref. 5047075SM) is a genuine Briggs & Stratton component for Simplicity lawn machinery. Made from durable metal with a protective black finish, it mounts on the engine crankshaft to transfer power reliably to belt-driven systems such as the cutter deck or drive system. This maintains smooth operation, reduces belt slip, and supports consistent performance. It is suitable for a wide range of Simplicity lawn tractors and zero-turn mowers, including models 1694763 and 1694764. Designed as a direct-fit replacement, it helps restore correct belt alignment and running, which is critical for cutting quality and drive responsiveness during routine mowing and heavier grounds maintenance.
