The Chelsea 823XJAKP-A6XW is an 823 Series Extra Heavy-Duty Power Take-Off built for high-torque applications including oil field, logging, and pumper cleaner trucks. It mounts via an 8-bolt PTO aperture and fits automatic and manual transmissions from Allison, Eaton/Fuller, Volvo/Mack, Daimler/Detroit, and other manufacturers. The mechanical lever shift design delivers output through an SAE C pump flange or driveline connection. The 823 Series is rated for intermittent torque in the 500 lb-ft range and supports continuous operation with a 30% de-rating. A cast iron housing and tapered cone bearings on the output shaft give this series its load-bearing capability in demanding vocational service. Available from Pro Gear and Transmission.
