Caterpillar 2S9006 Shaft

Caterpillar 2S-9006 is a genuine belt tightener pulley shaft, listed by Cat as part 2S-9006 with a length of 107.95 mm. This shaft is designed for use in belt tensioner assemblies to maintain proper tension and belt alignment within compatible Caterpillar drive systems. As an original Cat component, it aligns with Caterpillar belt drive configurations and interfaces with the tensioner pulley mounting and related fasteners according to Cat’s standard specifications. The 107.95 mm length is a key dimensional requirement for fitment within the tensioner housing and belt path, with exact compatibility dependent on the specific tensioner design used on a given machine model. To verify correct fit, consult Caterpillar official parts catalogs or a Cat dealer, referencing your machine model, serial number, and the belt tensioner assembly that uses the 2S-9006 shaft. This shaft supports reliable belt operation by providing a precise mounting point for the tensioner pulley, contributing to consistent belt tracking and reduced wear when installed as the correct Cat part.
