The Chelsea 252 Series Power Take-Off, part number 252GDHVX-B51449 or 252GDHVXB51449, is a hydraulic-shift PTO built for Allison automatic transmissions and RAM truck applications. It mounts with a 6-bolt pattern and drives a 1-inch round output shaft with a 1/4-inch key. Intermittent torque capacity is rated at 120 lb-ft (163 Nm) - verify your exact application on Chelsea's application pages for confirmed ratings. Shaft power output reaches 11 HP at 500 RPM and 23 HP at 1,000 RPM. The 252 Series integrates a cartridge valve directly into the housing, so only a single hydraulic hose connection is required during installation. Weather-tight electrical connectors and a controlled compression interface gasket are included as standard. Call us to confirm proper fit for your transmission and chassis.
