Gearbox Assembly
SAF-Holland

The gearbox assembly is a complete replacement unit that houses the gear train, bearings, and shafts required to transfer engine power to the drivetrain with reliable engagement and controlled backlash. This assembly emphasizes consistent gear tooth contact, robust bearing support, and proper lubrication pathways to maximize durability under heavy use. Replacing an aging or noisy gearbox assembly can restore smooth shifting, reduce vibration, and lower the risk of unexpected failures that disrupt fleet operations. The design enables straightforward installation in compatible powertrains and can help reduce downtime compared with piecemeal repairs. Attention to torque specifications and proper alignment during installation ensures optimal performance and longevity. Available through Source One Parts Center.
