The Chelsea 880XBAKP-M6SS or 880XBAKPM6SS is an 8-bolt, heavy-duty Power Take-Off from the Chelsea 880 Series, rated for up to 500 lb-ft (678 Nm) intermittent torque. It features a lever mechanical shift, a 1-1/2"-10T spline output shaft paired with a 1410 companion flange, and a cast iron housing. Shaft power is rated at 48 HP at 500 RPM and 95 HP at 1000 RPM, with 56+ HP continuous output capability. The 880 Series fits most 8-bolt manual transmissions, including Volvo/Mack, Allison, and Eaton/Fuller applications, and is suited for bulk haulers, fire trucks, oil field equipment, aerial units, and large recovery trucks. The removable shift cover simplifies backlash adjustment. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 880 Series is designed for high-torque, high- and low-speed applications using constant mesh input gears. Tapered cone bearings provide strong load-bearing capacity. Typical applications include bulk haulers, winch systems, fire trucks, oil field equipment, aerial trucks, and large recovery vehicles. The 880 Series is also available for the Eaton Endurant transmission. Output options across the series include SAE B, SAE BB, and SAE C pump flanges, as well as driveline configurations. Refer to Chelsea application pages to confirm torque ratings for your specific installation.
