The Chelsea 221 Series Power Take-Off Assembly, part number 221ZEAHX-A6RA or 221ZEAHXA6RA, is a 6-bolt mounted PTO designed for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. It uses a wire/cable mechanical shift and accepts compatible Hino, Allison, Eaton/Fuller, Volvo/Mack, and other transmission applications. The 1-1/4" round output shaft (with keyway) delivers up to 250 lb-ft intermittent torque and 48 HP at 1,000 RPM. A cast iron housing with tapered cone output bearings provides strong load-bearing capacity, and the greaseable pump shaft helps reduce spline fretting and corrosion. Both standard and low-profile housing options are available within the 221 Series. Call us to confirm proper fit for your application.
