The Chelsea 221XCAJP-W5RB or 221XCAJPW5RB is a 221 Series Power Take-Off assembly built for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. It mounts via a 6-bolt pattern and shifts by wire/cable mechanical actuation. The 1-1/4" round output shaft accepts a key, and rated output power reaches 46-55 HP (31-40 kW). Shaft power is rated at 24 HP (500 RPM) and 48 HP (1,000 RPM). Intermittent torque is rated up to 250 lb-ft (339 Nm) - verify actual torque for your specific application. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, and Hino. The cast iron housing is available in standard or low-profile configurations. Call us to confirm proper fit for your application.
The 221 Series uses a cast iron housing with tapered cone output shaft bearings for greater load-bearing capability compared to needle bearing designs. The 360-degree rotatable flange is one of twenty-six output options available across the series. Three internal speed ratios and eleven shift options are offered in the full 221 Series lineup. A self-lube option is available for transmissions that have difficulty supplying lubrication to the PTO. Typical applications include dump trucks, tow and recovery rigs, and aerial equipment.
