The Chelsea 892XAFJW-B5XV is a hydraulic hot-shift power take-off from the Chelsea 892 Series, designed specifically for Allison 4700 Series transmissions. It mounts via a 10-bolt configuration and positions the pump output flange to the rear of the transmission, providing improved clearance between the PTO and frame rail. The SAE C output shaft uses wet spline technology to extend pump spline life under demanding duty cycles. The 892 Series delivers 56+ HP (51+ kW) and intermittent torque ratings exceeding 501 lb-ft. A one-piece main shaft eliminates the input splines found in PTO-plus-extension designs. Common applications for this series include aerial trucks, fire and rescue apparatus, refuse trucks, and truck cranes. Pro Gear and Transmission carries this genuine Chelsea unit.
