The Chelsea 221 Series Power Take-Off, part number 221XEAJP-W3RB or 221XEAJPW3RB, is a 6-bolt mounted PTO built for low-speed, heavy-duty work. It uses a wire/cable mechanical shift and delivers output power in the 46-55 HP range, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with keyway connects directly to hydraulic pumps or driveline accessories. Compatible transmissions include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. The cast iron housing features tapered cone output bearings for strong load-bearing capability, and greaseable pump shafts help reduce spline fretting and corrosion over time. A low-profile housing option is available within the 221 Series. Call us to confirm proper fit for your specific transmission and application.
