The Chelsea 890RDFJW-B5XV or 890RDFJWB5XV is a 890 Series Power Take-Off Assembly built for Allison 3000 MD and 4000 HD series transmissions. It uses a 10-bolt mount and an SAE C ("XS") output shaft with hydraulic PowerShift engagement. The one-piece main shaft moves the PTO/pump mounting flange to the rear of the transmission, improving clearance between the pump and the frame rail without requiring a separate extension. Wet Spline Technology on the output extends spline life under continuous-duty demand. The 890 Series delivers up to 670 lb-ft continuous torque, with shaft power output of 64 HP at 500 RPM and 128 HP at 1000 RPM. Typical applications include aerial trucks, fire and rescue trucks, refuse trucks, and truck cranes. Call us to confirm proper fitment for your transmission configuration.
