The Chelsea 252GDHVP-B5P37 or 252GDHVPB5P37 is a hydraulic-shift, 6-bolt power take-off from the Chelsea 252 Series, designed for Allison 1000/2000/2400 series automatic transmissions and RAM truck applications. Output is through a 1-inch round 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 (check application pages for the actual torque rating for your configuration). A single hose connection and integrated cartridge valve simplify installation, and weather-tight electrical connectors protect the hydraulic control circuit. The 252 Series housing is sized to pass through a floor access panel without dropping the exhaust. Call us to confirm proper fit for your transmission and chassis.
