The Chelsea 890 Series Power Take-Off, part number 890CEFJW-B3XV or 890CEFJWB3XV, is a hydraulic PowerShift PTO engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. The 890 Series mounts via a 10-bolt pattern and locates the pump output to the rear of the transmission, providing clearance where side-mounted PTOs fall short. The SAE C ("XS") output shaft uses Chelsea's Wet Spline technology to extend pump spline life under demanding duty cycles. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. Continuous-duty torque capacity is rated up to 670 ft-lb, with intermittent torque exceeding 501 ft-lb. Common applications include aerial trucks, fire and rescue, refuse, and truck crane service. Call us to confirm proper fit for your specific transmission configuration.
