The Chelsea 890EFFJW-B5XK or 890EFFJWB5XK is a hydraulic PowerShift PTO assembly from the 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and positions the SAE C output flange at the rear of the transmission, providing clearance between the PTO and the frame rail without requiring a separate extension unit. The main shaft is a single one-piece design that eliminates the input splines found between a standard PTO and an output extension. The wet-spline output lubricates the PTO and pump shaft interface for longer service life in demanding duty cycles. Continuous torque rating reaches 670 ft-lb, with shaft power of 64 HP at 500 RPM and 128 HP at 1,000 RPM. A genuine Chelsea part from Pro Gear and Transmission.
