The Chelsea 252 Series Power Take-Off Assembly, part number 252RMKUX-B5P71 or 252RMKUXB5P71, is a hydraulic-shift PTO designed for Allison and RAM automatic transmissions. It mounts via a 6-bolt pattern and delivers a 1-inch round output shaft with a 1/4-inch key. Shaft power output is 11 HP at 500 RPM and 23 HP at 1000 RPM, with an intermittent torque rating in the 101-200 lb-ft range (check application pages for your specific torque figure). The integrated cartridge valve and single hose connection simplify installation, and weather-tight electrical connectors protect the shift circuit. The 252 Series housing is sized to pass through a standard floor access panel without dropping the exhaust system. Call us to confirm proper fit for your transmission and chassis.
