Based on the Endurant HD automated transmission, the new Endurant HD N model is optimized to integrate with the Cummins Westport ISX12N natural gas engine and features new software functionality and calibrations, and a new diaphragm spring clutch from Eaton that is designed to meet the thrust bearing load requirements of natural gas engines and protect the engine for optimal performance.
The integration between the engine and transmission results in improved launch performance, improved low-speed maneuverability, and smoother shifts when compared to previous natural gas engines and automated manual transmission combinations.
The new Cummins Westport ISX12N and Endurant HD N integrated powertrain is designed for fleets looking to reduce their carbon footprint and help support their sustainability initiatives.
