The Chelsea 252RDKUX-B5P37 or 252RDKUXB5P37 is a Chelsea 252 Series Power Take-Off engineered for Allison 1000/2000/2400 series and Aisin automatic transmissions used in Dodge/RAM truck chassis. The 252 Series uses hydraulic shift and a 6-bolt mounting pattern. Output options in the series include an SAE A pump flange, SAE A (5/8" 9-tooth) pump spline, 3/4" 11-tooth pump spline, and a round shaft with a 1-1/4" key. Series intermittent torque rating is 120 lb-ft. The integrated cartridge valve and single-hose connection design simplify installation compared to remote solenoid setups, and the housing profile is designed to pass through a floor access panel without dropping the exhaust system.
