The Chelsea 880XRAHX-A5AF or 880XRAHXA5AF is a heavy-duty 8-bolt power take-off assembly from the Chelsea 880 Series, built for high-torque, constant-mesh applications. It shifts via lever-mechanical control and mounts on most manual transmissions with an 8-bolt aperture, including Eaton/Fuller, Volvo/Mack, and Allison units. The output shaft is a 1-1/2"-10T spline with a 1410 series companion flange. Intermittent torque is rated up to 500 lb-ft (678 Nm); shaft power reaches 48 HP at 500 RPM and 95 HP at 1000 RPM. The dual-pump output design allows a hydraulic pump to be mounted on each end. Typical applications include fire trucks, bulk haulers, oil field equipment, aerial units, and large recovery trucks.
