The Chelsea 880QQMEX-D4XY is an 880 Series Power Take-Off built for 8-bolt manual transmission apertures. The 880 Series is Chelsea's heavy-duty PTO line, rated for intermittent torque up to 500 lb-ft (678 Nm) and output power of 56+ HP. Constant mesh input gears support both high- and low-speed, high-torque service. A lever-control shift is standard, with an optional air control shift available. The rugged cast iron housing uses tapered cone bearings for strong load-carrying capacity, and a removable shift cover makes backlash adjustment straightforward. Typical applications include bulk haulers, fire trucks, oil field equipment, winch drives, and large recovery trucks. Available from Pro Gear and Transmission.
