The Chelsea 221RCAJP-W3XD or 221RCAJPW3XD 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 uses a wire/cable mechanical shift. The 1-1/4" round output shaft accepts a standard key, and shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque for the 221 Series reaches up to 250 lb-ft (check application pages for actual torque ratings for this configuration). Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, and Hino, among others. Greaseable pump shafts reduce spline fretting and corrosion during extended service. Call us to confirm proper fit for your application.
The Chelsea 221 Series uses a cast iron housing and tapered cone bearings on the output shaft for extended service life under load. Tapered output bearings provide greater load-bearing capability compared to needle-bearing designs. The 221 Series supports continuous operation with a 30% de-rating. Cross-references for this part include 1450-221RCAJPW3XD and 1450221RCAJPW3XD. Note: Parker Chelsea lists the 221 Series as obsolete. Pro Gear and Transmission can help you confirm availability or identify a compatible current-production replacement - give us a call.
