The Chelsea 221XEAJP-W5XR or 221XEAJPW5XR is a 221 Series Power Take-Off from Parker Chelsea, designed for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. The 221 Series uses a cast iron housing with tapered cone output shaft bearings for greater load-bearing capability compared to needle-bearing designs. It mounts via a 6-bolt pattern and is compatible with Allison, Eaton/Fuller, Volvo/Mack, and other transmissions. The series supports Wire/Cable and Mechanical shift types and offers output options including SAE A, SAE B, SAE BB, and SAE C pump splines, as well as round and tapered shaft outputs. Continuous operation is supported with a 30% de-rating. Call us to confirm proper fit for your specific transmission and application.
