The Chelsea 880 Series Power Take-Off, part number 880XRAHX-H3AZ or 880XRAHXH3AZ, is an 8-bolt, lever mechanical shift PTO built for heavy-duty, high-torque applications. It delivers an intermittent torque rating of up to 500 lb-ft (678 Nm) and shaft power of 48 HP at 500 RPM or 95 HP at 1000 RPM. The output shaft is a 1-1/2"-10T spline paired with a 1410 companion flange, supporting driveline connections. The cast iron housing and tapered cone bearings handle the demands of fire trucks, oil field equipment, bulk haulers, aerial units, and large recovery trucks. A removable shift cover makes backlash adjustment faster and more precise. The dual-pump output allows mounting a hydraulic pump on each end of the unit. Fits 8-bolt transmission apertures from Volvo/Mack, Allison, Eaton/Fuller, and other manufacturers. Call us to confirm proper fit for your specific transmission application.
The Chelsea 880 Series is suited for bulk haulers, fire trucks, oil field equipment, aerial applications, winch systems, and large truck recovery. It accepts constant mesh input gears and is available for a wide variety of transmissions including the Eaton Endurant. The series supports SAE B, SAE C, and ISO 7652 pump flange output types in addition to the driveline companion flange configuration on this assembly.
