The Chelsea 890LDFJW-B5XS or 890LDFJWB5XS is a 890 Series hydraulic PowerShift power take-off designed for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and delivers a continuous torque rating up to 670 ft-lb, with intermittent torque rated at 501+ ft-lb. The SAE C output shaft uses Wet Spline Technology to extend pump shaft life in 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, locating the SAE C outlet flange for improved pump clearance without relying on a separate extension. Common applications include aerial trucks, fire and rescue, snow and ice equipment, and refuse trucks. Call us to confirm proper fit for your application.
