The Chelsea 252DMKUX-B51462 or 252DMKUXB51462 is a hydraulic-shift power take-off assembly from the Chelsea 252 Series, designed for Allison 1000/2000/2400 series automatic transmissions and RAM trucks with compatible automatic transmissions. It mounts via a 6-bolt pattern and delivers power through a 1-inch round output shaft with a 1/4-inch key. Shaft power ratings are 11 HP at 500 RPM and 23 HP at 1000 RPM, with intermittent torque in the 101-200 lb-ft range (verify your exact application in Chelsea's application pages). The integrated cartridge valve and single-hose hydraulic connection simplify installation, and the housing is sized to pass through a floor access panel without dropping the exhaust system. Call us to confirm proper fit for your specific chassis and transmission.
The Chelsea 252 Series housing is designed to pass through the floor access panel of Dodge/RAM trucks without requiring exhaust system removal, reducing installation time. Compatible Parker hydraulic pumps covering flows from 1.6 gpm to 8.2 gpm at 1000 RPM are available, and the PTO and pump can be ordered together under a single part number. Markets served include aerial, tow and recovery, tire service trucks, dump trucks, and vocational and municipal equipment. Continuous operation is supported with a 30% de-rating applied.
