The Chelsea 890 Series Power Take-Off, part number 890TDFJW-B5XS or 890TDFJWB5XS, is a hydraulic hot-shift PTO engineered 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, fitting between the transmission and the frame rail to improve pump clearance. The one-piece main shaft eliminates input splines between the PTO and output extension. The SAE C output shaft uses wet-spline technology to extend pump shaft life in demanding service. Continuous-duty torque reaches 670 ft-lb, with intermittent torque rated at 501+ ft-lb. Shaft power is 64 HP at 500 RPM and 128 HP at 1,000 RPM. A genuine Chelsea part from Pro Gear and Transmission.
