The Chelsea 880XQAHX-H3AZ or 880XQAHXH3AZ is an 880 Series Power Take-Off assembly built for heavy-duty applications including bulk haulers, fire trucks, oil field equipment, and large truck recovery. It mounts via an 8-bolt aperture and fits a broad range of manual transmissions from Allison, Eaton/Fuller, and Volvo/Mack. The lever mechanical shift operates constant-mesh input gears, and the removable shift cover allows straightforward backlash adjustment. Output is through a 1-1/2"-10T spline with a 1410 companion flange. The 880 Series is rated for intermittent torque up to 500 lb-ft (678 Nm) and delivers up to 95 HP (71 kW) at 1,000 RPM. Dual-pump output lets you mount a hydraulic pump on each end. Call us to confirm proper fit for your application.
The Chelsea 880 Series is suited for oil and gas, aerial, mining, on-highway, and other mobile markets. Typical applications include bulk haulers, winch systems, fire trucks, oil field equipment, aerial equipment, and large truck recovery. The 880 Series is also compatible with the Eaton Endurant transmission. Tapered cone bearings provide load-bearing capability across high-torque, variable-speed duty cycles.
