The Chelsea 880XRDAX-A6GS is an 880 Series 8-bolt Power Take-Off designed for heavy-duty manual transmission applications. The 880 Series fits transmissions with an 8-bolt aperture and uses constant mesh input gears for reliable operation in high-torque, high- and low-speed service. Shift control is a standard lever mechanical design. Output options in the 880 Series include SAE B, SAE C, and ISO 7652 pump flanges, as well as driveline configurations. The cast iron housing supports a removable shift cover that simplifies backlash adjustment during installation. Typical applications for the 880 Series include bulk haulers, fire trucks, oil field equipment, aerial units, winch systems, and large recovery trucks.
