The Chelsea 880 Series Power Take-Off Assembly, part number 880XQAHX-A6XY or 880XQAHXA6XY, is an 8-bolt, lever mechanical shift PTO built for high-torque, heavy-duty service. The output shaft is a 1-1/2"-10T spline paired with a 1410 Series Companion Flange, rated for up to 500 lb-ft intermittent torque. Shaft power output reaches 48 HP at 500 RPM and 95 HP at 1,000 RPM. A cast iron housing holds up in demanding environments, and the removable shift cover makes backlash adjustment straightforward during installation. The dual-pump output configuration allows a hydraulic pump to be mounted on each end of the unit. Compatible with a wide range of transmissions including Volvo/Mack, Allison, and Eaton/Fuller. Typical applications include bulk haulers, fire trucks, oil field equipment, aerial units, and large recovery trucks. Call us to confirm proper fit for your specific transmission and application.
