The Chelsea 890RFFJW-B5XK or 890RFFJWB5XK 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 mounts via a 10-bolt pattern with an additional rear bracket for support, positioning the SAE C output flange at the rear of the transmission to open clearance between the pump and the frame rail. The one-piece main shaft eliminates the input splines found in PTO-plus-extension configurations. Wet Spline technology on the output shaft reduces wear in high-cycle applications. Hydraulic PowerShift engagement allows on-the-go clutching. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. Call us to confirm proper fit for your specific transmission configuration.
