The Chelsea 890REFJW-G5XV or 890REFJWG5XV is a hydraulic PowerShift power take-off from the Chelsea 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and locates the SAE C output flange at the rear of the transmission, moving the pump mounting point back to clear tight frame-rail installations. The main shaft is a one-piece design that eliminates the input splines between the PTO body and output extension, while wet-spline output technology reduces wear on both PTO and pump shaft in continuous-duty use. Continuous-duty torque rating for the 890 Series reaches 670 ft-lb, with intermittent torque capability of 501+ lb-ft. Shaft power output is 64 HP at 500 RPM and 128 HP at 1,000 RPM.
