The Chelsea 890HAFJW-B5ZS or 890HAFJWB5ZS is a 890 Series Power Take-Off designed for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and shifts hydraulically via PowerShift. Output is through an SAE C ("XS") flange, delivering continuous-duty torque of 670 lb-ft and intermittent torque rated at 501+ lb-ft. Shaft power reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. The wet-spline lubrication option (W designation) extends PTO and pump shaft life, and the extended shaft design improves pump clearance. Call us to confirm proper fit for your application.
