The Chelsea 880 Series Power Take-Off Assembly, part number 880XBAKX-M6XK or 880XBAKXM6XK, is an 8-bolt PTO designed for heavy-duty manual transmission applications including Eaton/Fuller, Volvo/Mack, and Allison. It features a lever-mechanical shift and a 1-1/2"-10T spline output shaft fitted with a 1410 companion flange. The 880 Series is rated for intermittent torque of 401-500 lb-ft (501+ Nm), with shaft power output reaching 95 HP at 1,000 RPM. Common applications include fire trucks, bulk haulers, oil field equipment, winch systems, aerial units, and large truck recovery vehicles. A removable shift cover simplifies backlash adjustment during installation. Contact Pro Gear and Transmission to confirm fitment for your specific transmission.
The Chelsea 880 Series is suited for demanding on-highway and off-highway applications, including oil and gas, aerial, mining, fire suppression, and large-vehicle recovery. The 880 Series PTO uses constant mesh input gears and tapered cone bearings to handle both high-speed and high-torque demands. The shift cover is fully removable, making backlash adjustment faster and more accurate in the field. For applications requiring pump-on-pump output, the dual-pump design accommodates a hydraulic pump at each end of the unit. Call Pro Gear and Transmission to confirm this part number fits your specific transmission model and configuration.
