The Chelsea 880XMAHP-A3AZ is an 880 Series Power Take-Off built for heavy-duty, high-torque work. The 880 Series fits most manual transmissions with an 8-bolt aperture and is rated for up to 500 lb-ft of intermittent torque. Constant mesh input gears support both high- and low-speed operation, while tapered cone bearings handle demanding load conditions. The standard shift type is lever/mechanical control. Output options across the 880 Series include SAE B, SAE C, and ISO 7652 pump flanges as well as driveline configurations. Typical applications for this series include bulk haulers, fire trucks, oil field equipment, aerial units, winch systems, and large recovery trucks. The rugged cast iron housing and removable shift cover simplify backlash adjustment during installation. Available from Pro Gear and Transmission.
