The Caterpillar A000011952 Sheave is a genuine Cat replacement pulley wheel used in drive and lifting systems across Caterpillar equipment. This grooved wheel guides a rope or belt through a controlled curvature, supporting the loading conditions typical of heavy‑duty service and preserving drive efficiency by reducing belt wear and misalignment when correctly installed. Because Cat parts are matched to specific machines and configurations, the A000011952 must be verified against your model and serial number; exact bore size, groove width, mounting method, and bearing arrangement are cataloged in Caterpillar's official parts manuals, with installation instructions and torque specifications available through the Cat Parts Store or your local dealer. Use this replacement to restore performance in Cat power‑transmission assemblies, ensuring consistent tension and reliable operation; always consult the official documentation to confirm compatibility and to obtain any required fasteners or adapters for a proper fit. Authenticity is guaranteed by Caterpillar branding and catalog number verification, helping assure compatibility with Cat service procedures and dealer support.
