The Chelsea 890HDFJW-B5XK or 890HDFJWB5XK is a hydraulic hot-shift Power Take-Off from the Chelsea 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It uses a 10-bolt mounting pattern and delivers an SAE C ("XS") output flange, placing the pump mounting point at the rear of the transmission to provide clearance where side-mount PTOs fall short. The one-piece main shaft eliminates the input splines between the PTO and output extension, and the wet-spline output extends pump shaft life in demanding service. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. Continuous-duty torque rating is up to 670 ft-lb; intermittent torque rating is 501+ ft-lb. Common applications include fire and rescue, aerial trucks, refuse, and truck cranes. Call us to confirm proper fit for your application.
