The Chelsea 252 Series Power Take-Off Assembly, part number 252RDKUX-B51126 or 252RDKUXB51126, is a hydraulic-shift PTO built for Allison 1000/2000/2400 series automatic transmissions and RAM trucks with Aisin automatic transmissions. It mounts via a 6-bolt pattern and delivers a 1-inch round output shaft with a 1/4-inch keyway. Shaft power is rated at 11 HP (500 RPM) and 23 HP (1000 RPM), with intermittent torque in the 101-200 lb-ft range (verify your application-specific rating on the Chelsea application pages). An integrated cartridge valve and single hose connection simplify installation, and the housing is designed to pass through a floor access panel without dropping the exhaust system. Call us to confirm proper fit for your application.
