The Chelsea 880 Series Power Take-Off, part number 880XBAKP-A4XK or 880XBAKPA4XK, is an 8-bolt, lever mechanical shift PTO built for heavy-duty, high-torque applications. It mounts to manual transmissions with an 8-bolt aperture, including Eaton/Fuller, Volvo/Mack, and Allison units. The output shaft is a 1-1/2"-10T spline with a 1410 companion flange, rated for intermittent torque up to 500 lb-ft (678 Nm). Shaft power is 48 HP at 500 RPM and 95 HP at 1,000 RPM. The dual-pump output design allows a pump to be mounted on each end of the unit. Typical applications include fire trucks, bulk haulers, oil field equipment, winch systems, and large recovery trucks. Call us to confirm proper fit for your application.
The Chelsea 880 Series is designed for continuous operation with a 30% de-rating. Constant mesh input gears support both high- and low-speed operation, and tapered cone bearings provide load-bearing strength suited to demanding cycles. The 880 Series is available for a wide range of transmissions, including the Eaton Endurant. Common markets include oil and gas, aerial work, mining, and on-highway applications such as fire apparatus and large tow and recovery vehicles.
