The Chelsea 890TDFJW-B5XK is a hydraulic PowerShift Power Take-Off from the Chelsea 890 Series, engineered specifically for Allison 3000 and 4000 Series transmissions. The 890 Series mounts via a 10-bolt pattern and positions the pump output flange at the rear of the transmission, improving clearance between the PTO, pump, and frame rail. The output shaft is SAE C type with Wet Spline technology, which extends service life on the PTO and pump shaft under demanding duty cycles. The main shaft is a single one-piece design, eliminating input splines between the PTO body and the output extension. The series delivers intermittent torque ratings above 501 lb-ft and output power above 56 HP. A genuine Chelsea part, available from Pro Gear and Transmission.
