The Chelsea 890 Series Power Take-Off Assembly, part number 890LEFJW-K5XK or 890LEFJWK5XK, is a hydraulic hot-shift PTO engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts with a 10-bolt pattern and delivers an SAE C ("XS") output flange with wet-spline technology to extend PTO and pump shaft life under demanding duty cycles. Continuous torque rating reaches 670 ft-lb, with intermittent torque above 501 ft-lb. Shaft power output is 64 HP at 500 RPM and 128 HP at 1,000 RPM. The one-piece main shaft eliminates input splines between the PTO and output extension, and the extended shaft design moves the pump mounting flange to the rear of the transmission for improved clearance between the pump and frame rail. A genuine Chelsea part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
