The Chelsea 890EDFJW-B5XS or 890EDFJWB5XS is a hydraulic PowerShift PTO assembly from the Chelsea 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and uses a one-piece main shaft that eliminates input splines between the PTO and output extension, tucking the gear section tightly against the transmission for clearance. The SAE C output shaft uses Wet Spline technology to extend pump spline life in demanding cycles. Continuous-duty torque reaches 670 ft-lb, with intermittent torque rated at 501+ ft-lb. Shaft power is 64 HP at 500 RPM and 128 HP at 1,000 RPM. Typical applications include aerial trucks, fire and rescue, refuse, and truck crane equipment. Available from Pro Gear and Transmission.
