Description
CAT 261-8553 – Pinion transmits rotational motion through the motor grader’s circle drive assembly. It rotates the main structure, enabling the operator to alter, pitch, and pivot the earthmoving blade structure with high accuracy. This gear directly replaces or cross-references with legacy production codes, including 8W-5092 (or 8W5092), 6G-5051, and 422-9842.
