The Chelsea 892 Series Power Take-Off, part number 892UAFJW-B5XV or 892UAFJWB5XV, is a hydraulic PowerShift PTO engineered for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and features an SAE C outlet flange with an SAE C extended (XS) output shaft. The continuous-duty torque rating reaches 670 ft-lb (908 Nm), and intermittent torque capacity exceeds 501 ft-lb. Output power rates at 56+ HP at the series level, with shaft power of 64 HP at 500 RPM and 128 HP at 1,000 RPM. The 892 Series positions the pump output flange to the rear of the transmission, improving clearance in tight installations. A one-piece main shaft eliminates the input splines found in extension-type designs. Wet-spline lubrication is standard on this unit, extending spline life in demanding duty cycles.
