The Chelsea PTO Assembly 252DDKUX-B5XE or 252DDKUXB5XE is a hydraulic-shift power takeoff designed to mount on Allison and RAM transmissions using a 6-bolt mounting interface. Output is delivered through a 1-inch round shaft with key. Intermittent torque is rated at 120 lb-ft (163 Nm) - verify actual ratings on the application pages for your specific installation. Shaft power output reaches 23 HP (17 kW) at 1,000 RPM and 11 HP (9 kW) at 500 RPM, with a maximum continuous output of 25 HP (20 kW). A single hose connection and integrated cartridge valve simplify hydraulic plumbing.
