The Chelsea 880GMAHX-A4GS or 880GMAHXA4GS is a heavy-duty 880 Series Power Take-Off Assembly built for 8-bolt manual transmission apertures. It uses a lever mechanical shift, delivers up to 500 lb-ft intermittent torque (678 Nm), and puts out 48 HP at 500 RPM or 95 HP at 1000 RPM through a 1-1/2"-10T spline output shaft fitted with a 1410 companion flange. A dual-pump output configuration allows a hydraulic pump to mount on each end simultaneously. The removable shift cover simplifies backlash adjustment during installation. Compatible transmissions include Volvo/Mack, Allison, and Eaton/Fuller applications. Common uses include fire trucks, bulk haulers, oil field equipment, winch rigs, and large recovery trucks.
