The Chelsea 890 Series Power Take-Off 890UEFJW-B5XV or 890UEFJWB5XV is a hydraulic PowerShift PTO engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and positions the pump output flange to the rear of the transmission, creating clearance between the PTO and the frame rail without requiring an extension - the main shaft is a single one-piece unit with no input splines between the PTO body and output extension. The SAE C output uses Wet Spline Technology to extend pump shaft life under demanding duty cycles. Continuous-duty torque rating reaches 670 lb-ft, with intermittent torque exceeding 501 lb-ft. Shaft power output is 64 HP at 500 RPM and 128 HP at 1,000 RPM. Typical applications include aerial trucks, fire and rescue, refuse trucks, and truck cranes.
