The Chelsea 890NEFJW-B3CF or 890NEFJWB3CF is a hydraulic powershift Power Take-Off from the 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and uses a one-piece main shaft, positioning the SAE C output flange at the rear of the transmission to provide clearance between the PTO and the frame rail. The wet-spline output extends pump shaft service life under demanding duty cycles. Continuous torque capacity for the 890 Series reaches 670 ft-lb, with shaft power output rated at 64 HP at 500 RPM and 128 HP at 1,000 RPM. Common applications include aerial trucks, fire and rescue equipment, refuse trucks, and truck cranes. Call us to confirm proper fit for your chassis and transmission configuration.
