Caterpillar 9W-1571 Slinger

Caterpillar 9W-1571 Slinger is an OEM Cat dirt- and liquid-deflector (slinger) designed for select Cat track-type tractors and pipelayers. The part number 9W-1571 is specified to fit 583T and the PL72, PL83, and PL87 configurations, ensuring a correct mating interface with those machines’ slinger assemblies. One defining spec is a 175 mm inside diameter, which governs the size of the mounting opening and compatible counterpart components in the deflector assembly. In Caterpillar catalogs, slingers of this type are described as debris-control accessories that help redirect material and splash away from the operator area and key housings during operation, a consideration in pipeline work and heavy earthmoving tasks. As an official Cat replacement, the 9W-1571 is designed to integrate with Cat’s standard mounting patterns on the 583T/PL83/PL87 family, providing a straightforward replacement path and consistent performance in demanding job-site conditions.
