The Chelsea 880XRDAX-A5AF or 880XRDAXA5AF is an 880 Series Power Take-Off assembly built for heavy-duty, high-torque applications. It mounts via an 8-bolt aperture and fits a wide range of manual transmissions including Eaton/Fuller, Volvo/Mack, and Allison. The output is a 1-1/2"-10T spline shaft with a 1410 companion flange, rated for intermittent torque up to 500 lb-ft (678 Nm). Shaft power output is 48 HP at 500 RPM and 95 HP at 1,000 RPM. The 880 Series is well suited for bulk haulers, fire trucks, oil field equipment, winch applications, and large recovery trucks. A removable shift cover simplifies backlash adjustment at installation. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 880 Series is designed for high and low speed, high-torque applications using constant mesh input gears. Tapered cone bearings provide strong load-bearing capability. The dual-pump output design allows a hydraulic pump to be mounted on each end of the PTO. Typical applications include bulk haulers, fire trucks, oil field equipment, aerial equipment, winch systems, and large truck recovery vehicles. The 880 Series is also available for the Eaton Endurant transmission. For additional application and installation guidance, refer to the 880 Series Owner's Manual (Parker document HY25-2880-M1_US) and Chelsea Service Manual (HY25-6880-M1/US).
