The Chelsea 880XQAHX-H3GS or 880XQAHXH3GS is an 8-bolt, heavy-duty Power Take-Off assembly from the Chelsea 880 Series, designed for high-torque, constant-mesh input applications across a range of manual transmissions including Eaton/Fuller, Volvo/Mack, and Allison. The output shaft is a 1-1/2"-10T spline fitted with a 1410 companion flange, and the unit shifts via lever mechanical control. Intermittent torque rating for the 880 Series reaches 500 lb-ft (678 Nm); verify actual rating for your specific application on Chelsea's application pages. Shaft power output reaches 48 HP at 500 RPM and 95 HP at 1000 RPM. The removable shift cover simplifies backlash adjustment, and the dual-pump output allows a hydraulic pump to be mounted on each end. Typical applications include fire trucks, bulk haulers, oil field equipment, aerial units, and large recovery trucks. A genuine Chelsea part, available from Pro Gear and Transmission.
