Bevel Gears & Pinions

Caterpillar Bevel Gears and Pinions for Precise Power Transmission

Caterpillar bevel gears and pinions are essential components in the drive and steering systems of CAT machinery, designed to transmit power efficiently at right angles between intersecting shafts. These highly engineered parts are made from hardened, wear-resistant steel for maximum durability and long service life under heavy loads and in tough working conditions. Bevel gears mesh precisely with pinions to change the direction of rotation, enabling smooth operation of differentials, final drives, and steering systems in dozers, loaders, excavators, and other heavy equipment.

Each component is manufactured to exact tolerances and matched to specific CAT machine models, ensuring reliable performance and compatibility with your equipment. Regular inspection and timely replacement of worn gears or damaged pinions help prevent driveline failures, costly downtime, and further damage to related components. Propel Parts supplies a comprehensive selection of genuine or high quality bevel gears and pinions, with clear part number listings and fast shipping for dependable repairs.

All our gears and pinions are manufactured using the latest in measuring and 3D modeling equipment to ensure our parts are manufactured to engineering specifications. We do in-house quality control every step of the way analyzing each batch of steel, forging batches, cutting process, heat treating and final testing to ensure our parts are interchangeable with the OE. Our Bevel Gears and Gear Sets are: - 100% rolling tested against master gears to check for proper match, noise and any small imperfections that may have been created in handling or heat-treating. - Quench pressed during heat treatment to minimize distortion and maximize close tolerances. Grounded with a machine that uses diamond honing to remove most of the distortion and imperfections created during heat -treatment. - Shot peening and micro finishing are used to relieve the stress created in the material of the gear during the forging, cutting and heat treating processes.
