The Chelsea 890LFFJW-B5XV or 890LFFJWB5XV is a hydraulic PowerShift PTO assembly from the Chelsea 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It uses a 10-bolt mounting configuration and delivers an SAE C (XS) output via a one-piece main shaft, eliminating the input splines found in PTO-plus-extension designs. The clutch sits at the rear of the housing so the gear section tucks tightly against the transmission, positioning the pump output to the rear for improved frame-rail clearance. Wet-spline output technology protects the pump shaft in demanding, continuous-duty applications. The 890 Series carries a continuous-duty torque rating up to 670 ft-lb and intermittent torque rated at 501+ ft-lb. Shaft power reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. Call us to confirm proper fit for your application.
