The Chelsea 890LDFJW-B5XK or 890LDFJWB5XK is a 890 Series Power Take-Off assembly engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts with a 10-bolt pattern and shifts via hydraulic powershift. The SAE C ("XS") output shaft delivers up to 670 lb-ft of continuous torque and handles intermittent loads exceeding 501 lb-ft. An extended shaft design moves the pump mounting flange to the rear of the transmission, improving pump clearance on tight installations. The wet-spline output lubricates the PTO-to-pump interface to extend spline life. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. A genuine Chelsea part, sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
