The Chelsea 880XMDAX-H5XS is an 880 Series Power Take-Off built for 8-bolt manual transmission apertures. The 880 Series is rated for up to 500 lb-ft of intermittent torque and supports continuous operation with a 30% de-rating. Lever and mechanical shift types are standard, with an optional air control shift available. Constant-mesh input gears handle both high- and low-speed, high-torque demands. A rugged cast iron housing and tapered cone bearings carry heavy loads, while the removable shift cover makes backlash adjustment straightforward. Typical applications include bulk haulers, fire trucks, oil field equipment, winch systems, and large recovery trucks. Available from Pro Gear and Transmission.
