Atlas Copco 4812028111 Compound Drive Assembly

The Atlas Copco 4812028111 compound drive is a critical propulsion component designed for integration into the track drive system of specified asphalt pavers. It functions as the final drive unit, converting hydraulic motor output into high-torque rotational force for track movement. This assembly is engineered to withstand the high shock loads, abrasive environments, and continuous duty cycles inherent in asphalt paving applications. It features hardened gear profiles and robust bearing arrangements to ensure service life under heavy machine operating weights. The unit interfaces directly with the hydraulic drive motor and track sprocket assembly. Compatibility is verified for Dynapac F2500C, Dynapac SD2550CS, and Mauldin 1360 model series pavers.
