The Chelsea 221 Series Power Take-Off, part number 221XLDAX-A3RB or 221XLDAXA3RB, 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 features a 1-1/4" round output shaft with keyway. Intermittent torque rating for the 221 Series runs up to 250 lb-ft (339 Nm); verify actual rating on the application pages for your specific configuration. Output power reaches 48 HP at 1,000 RPM and 24 HP at 500 RPM. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. Greaseable pump shafts control spline fretting and corrosion. Call us to confirm proper fit for your transmission and application.
The Chelsea 221 Series uses a cast iron housing with tapered cone bearings on the output shaft for strong load-bearing capability. The series offers a choice of standard or low-profile housing to suit tight underhood clearances. Twenty-six output options are available across the 221 Series, including Chelsea's 360-degree rotatable flange. A self-lube option is available for transmissions that have difficulty delivering lubrication to the PTO. Typical applications include dump trucks, tow and recovery rigs, and aerial equipment.
