The Chelsea 880XDAKP-M3XS is an 880 Series 8-bolt Power Take-Off built for heavy-duty, high-torque applications. The 880 Series fits most manual transmissions with an 8-bolt aperture and is rated for up to 500 lb-ft of intermittent torque, with continuous operation available at a 30% de-rating. Constant mesh input gears support both high- and low-speed operation, and the series accommodates lever or air control shift. Tapered cone bearings handle heavy loads, and the removable shift cover simplifies backlash adjustment. Typical applications include fire trucks, bulk haulers, oil field equipment, aerial units, winch systems, and large recovery trucks. A genuine Chelsea part, available from Pro Gear and Transmission.
