The Chelsea 221 Series Power Take-Off, part number 221XLDAX-W5XK or 221XLDAXW5XK, 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 an intermittent torque rating up to 250 lb-ft (339 Nm) - check application pages for actual torque ratings for your specific installation. Output is rated at 46-55 HP (31-40 kW), with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with keyway suits common hydraulic pump connections. Fits transmissions from Allison, Eaton/Fuller, Volvo/Mack, Hino, and other manufacturers. Call us to confirm proper fit for your application.
The Chelsea 221 Series uses a cast iron housing with tapered cone bearings on the output shaft for strong load-bearing capability under sustained use. The series offers twenty-six output options including a 360-degree rotatable flange, three internal speed ratios, and eleven shift options. A self-lube option is available for transmissions that have difficulty supplying lubrication to the PTO. The space-saving shift cover is designed to maximize clearance under the truck. Typical applications include dump trucks, tow and recovery, and aerial equipment. Part number 221XLDAX-W5XK is also referenced as 221XLDAXW5XK.
