The Chelsea 890HBFJW-K5XS or 890HBFJWK5XS is a hydraulic hot shift power take-off from Chelsea's 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. The 10-bolt mount positions the SAE C flange output to the rear of the transmission, clearing the frame rail and giving hydraulic pumps the room they need. A one-piece main shaft eliminates the input splines between the PTO and output extension, and the wet-spline output extends pump shaft life in demanding duty cycles. Continuous torque rating reaches 670 ft-lb, with intermittent torque rated at 501 ft-lb and above. Shaft power delivery is 64 HP at 500 RPM and 128 HP at 1,000 RPM. Common applications include aerial trucks, fire and rescue, refuse, and snow and ice equipment. Call us to confirm proper fit for your application.
