The Chelsea 880 Series Power Take-Off Assembly, part number 880ZTAHX-A3AF or 880ZTAHXA3AF, is an 8-bolt, heavy-duty PTO built for high-torque, high-cycle applications such as bulk haulers, fire trucks, oil field equipment, large recovery trucks, and aerial units. It uses a lever mechanical shift and delivers up to 500 lb-ft of intermittent torque. The output shaft is a 1-1/2"-10T spline with a 1410 companion flange. Shaft power ratings are 48 HP at 500 RPM and 95 HP at 1,000 RPM. Tapered cone bearings handle heavy radial and thrust loads, and the removable shift cover simplifies backlash adjustment during installation.
