The Chelsea 880XBAKP-M4XY is an 880 Series Power Take-Off designed for 8-bolt manual transmission apertures. The 880 Series fits a wide range of transmissions, including Eaton Endurant, Eaton/Fuller, Allison, Volvo/Mack, and Daimler/Detroit units. It uses constant mesh input gears and a standard lever control shift, with an optional air control shift. Tapered cone bearings handle heavy radial and axial loads, and the removable shift cover makes backlash adjustment straightforward. The series is rated for up to 500 lb-ft of intermittent torque and supports continuous operation with a 30% de-rating. Typical applications include bulk haulers, fire trucks, oil field equipment, aerial units, winch systems, and large truck recovery. Available from Pro Gear and Transmission.
