The Chelsea 221XCAJP-A3XD or 221XCAJPA3XD is a 6-bolt mounted power take-off assembly from the Chelsea 221 Series, designed for low-speed, heavy-duty applications such as dump trucks, tow and recovery, and aerial equipment. Shift is wire/cable mechanical. The 1-1/4" round output shaft with key is built around tapered cone output bearings for greater load-bearing capability than needle-bearing designs. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Intermittent torque falls in the 201-300 lb-ft range; check application pages for the actual torque rating specific to your installation. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, and Hino. Greaseable pump shafts reduce spline fretting and corrosion over time. Available in a standard housing or a special low-profile housing for tight clearance installations. Also referenced as S-12811, CHE-221XCAJP-A3XD, and TG6SU6005A1BP. Call us to confirm proper fit for your transmission and application.
The 221XCAJP-A3XD is part of the Chelsea 221 Series PTO family, a cast iron housing unit built for low-speed, heavy-duty vocational service. The series supports twenty-six output options and three internal speed ratios. The 360-degree rotatable flange option is available within the series. A self-lube option is available for transmissions with lubrication delivery issues. Typical applications include dump trucks, tow and recovery vehicles, and aerial equipment. The low-profile housing variant maximizes clearance under the truck where space is limited.
