The Chelsea 890HAFJW-G5XK or 890HAFJWG5XK is a 890 Series Power Take-Off assembly engineered for Allison 3000 MD and 4000 HD series transmissions. It mounts via a 10-bolt pattern and shifts through a hydraulic powershift (hydraulic) mechanism. The SAE C ("XS") output shaft rides on a wet-spline lubricant setup, extending PTO and pump shaft service life. An extended shaft design improves pump clearance at installation. Continuous-duty torque is rated up to 670 lb-ft, with intermittent torque capability exceeding 501 lb-ft. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM.
