The Chelsea 890HCFJW-B5XK or 890HCFJWB5XK is a hydraulic hot-shift Power Take-Off from Chelsea's 890 Series, engineered specifically for Allison 3000 MD and 4000 HD series transmissions. It mounts via a 10-bolt pattern and delivers an SAE C ("XS") output flange. Shaft power rates at 64 HP at 500 RPM and 128 HP at 1,000 RPM. Continuous-duty torque reaches 670 lb-ft, with intermittent torque rated at 501+ lb-ft. The one-piece main shaft eliminates input splines between the PTO and the output extension, and the wet-spline output extends pump shaft life in demanding duty cycles. The 890 Series locates the pump output to the rear of the transmission, improving clearance between the pump and the frame rail. A genuine Chelsea part, available from Pro Gear and Transmission.
