Description
The Chelsea 252 Series Power Take-Off Assembly, part number 252RDKUX-B51462 or 252RDKUXB51462, is a hydraulic-shift PTO built for Allison 1000/2000/2400 series and RAM automatic transmissions. It mounts via a 6-bolt pattern and delivers output through a 1-inch round shaft with keyway. Intermittent torque is rated at 120 lb-ft (163 Nm); check application pages for torque ratings specific to your installation. Shaft power runs 11 HP at 500 RPM and 23 HP at 1000 RPM. The integrated cartridge valve and single-hose connection simplify installation significantly compared to remote-solenoid designs. The housing is sized to pass through a floor access panel without dropping the exhaust system. Sold by Pro Gear and Transmission. Call us to confirm fit for your specific chassis.
