The Chelsea 892HBFJW-B5XS or 892HBFJWB5XS is a hydraulic PowerShift power take-off from the 892 Series, designed for Allison 3000 MD and 4000 HD Series transmissions. It uses a 10-bolt mounting pattern and delivers output through an SAE C flange with a wet-spline SAE C extended output shaft. The extended shaft positions the pump output to the rear of the transmission, improving clearance between the pump and the frame rail. Continuous-duty torque reaches 670 ft-lb; intermittent torque ratings exceed 501 lb-ft. At 1,000 RPM the shaft delivers up to 128 HP. The one-piece main shaft eliminates input splines between the PTO body and the output extension, and the wet-spline output extends pump spline life in demanding service. Call us to confirm proper fit for your specific transmission configuration.
