The Chelsea 890LGFJW-B5XK or 890LGFJWB5XK is a hydraulic hot-shift power take-off from the 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and delivers a continuous-duty torque rating up to 670 ft-lb, with intermittent torque starting at 501 ft-lb. The SAE C ("XS") output shaft uses Wet Spline technology to extend PTO and pump shaft service life under demanding duty cycles. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. The 890 Series moves the pump mounting flange to the rear of the transmission, positioning the output away from tight frame-rail clearances. Hydraulic PowerShift engagement allows hot-shifting under load. A genuine Chelsea part, available from Pro Gear and Transmission.
