The Chelsea 252RDKUX-B5AD (also listed as 252RDKUXB5AD) is a hydraulic-shift PTO assembly built for Allison and RAM transmission applications. It mounts via a 6-bolt pattern and delivers up to 23 HP (17 kW) at 1,000 RPM through a 1-inch round keyed output shaft. Intermittent torque rating reaches 120 lb-ft (163 Nm) -- verify actual torque against Chelsea application pages for your specific installation. A single hose connection with an integrated cartridge valve keeps the hydraulic plumbing clean, while a Controlled Compression Interface Gasket seals the mounting face and Weather Tight Electrical Connectors protect the solenoid circuit.
