The Chelsea 890NEFJW-B3XV or 890NEFJWB3XV is a hydraulic hot-shift power take-off from the Chelsea 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and uses a hydraulic PowerShift engagement. The SAE C (XS) output shaft carries a continuous torque rating up to 670 lb-ft and an intermittent rating of 501+ lb-ft. Shaft power is rated at 64 HP at 500 RPM and 128 HP at 1,000 RPM. The wet-spline output extends pump shaft life under demanding conditions. The extended one-piece main shaft moves the pump mounting flange rearward, improving clearance between the pump and frame rail. Common applications include aerial trucks, fire and rescue units, refuse trucks, and truck cranes. Call us to confirm proper fit for your application.
