The Chelsea 221 Series Power Take-Off, part number 221ZCAHX-A3XQ or 221ZCAHXA3XQ, is a 6-bolt mounted PTO built for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. It uses a wire/cable mechanical shift and delivers output power in the 46-55 HP (31-40 kW) range. The 1-1/4" round output shaft accepts a key for direct drive connections. A cast iron housing with tapered cone output bearings provides strong load-bearing capability. Greaseable pump shafts reduce spline fretting and corrosion over time.
