The Chelsea 890HBFJW-B5XK or 890HBFJWB5XK is a 890 Series Power Takeoff assembly designed for Allison 3000 MD and 4000 HD series transmissions. It mounts with a 10-bolt pattern and shifts via hydraulic PowerShift. The output is an SAE C ("XS") extended shaft configuration, which improves pump clearance over standard-length setups. Continuous-duty torque rating is 670 lb-ft (908 Nm); intermittent torque exceeds 501 lb-ft. Shaft power output is 64 HP at 500 RPM and 128 HP at 1,000 RPM.
