The Chelsea 892HEFJW-B5AF or 892HEFJWB5AF is a Series 892 Power Take-Off assembly engineered for Allison 3000 MD and 4000 HD series transmissions. It mounts via a 10-bolt pattern and uses hydraulic PowerShift (PowerShift Hydraulic) engagement. The SAE C ("XS") extended output shaft improves pump-to-PTO clearance, a practical advantage in tight installations. Wet-spline lubrication is built in to reduce wear on the PTO and pump shaft interface over time. Continuous-duty torque is rated at 670 lb-ft (908 Nm), with intermittent capability above 501 lb-ft. Shaft power output reaches 128 HP at 1,000 RPM. Sold by Pro Gear and Transmission. Call us to confirm proper fitment for your specific application.
