The Chelsea 252 Series Power Take-Off Assembly, part number 252GDHVP-B5P82 or 252GDHVPB5P82, is a hydraulic-shift PTO built for Allison and RAM automatic transmission applications. It mounts via a 6-bolt pattern and drives a 1-inch round output shaft with a key. Intermittent torque is rated in the 101-200 lb-ft range (check application pages for actual torque ratings specific to your installation). Shaft power output is rated at 11 HP at 500 RPM and 23 HP at 1000 RPM. The integrated cartridge valve and single-hose connection reduce installation time, and the weather-tight electrical connectors protect against the elements. Call us to confirm proper fit for your specific transmission and chassis.
The Chelsea 252 Series is designed for Allison 1000/2000/2400 series automatic transmissions and Aisin automatic transmissions found in Dodge/RAM trucks. The housing profile is sized to pass through a floor access panel without requiring removal of the exhaust system. Compatible applications include tow and recovery vehicles, tire service trucks, dump trucks, and aerial equipment. Parker also offers a selection of matching pumps with flows from 1.6 gpm to 8.2 gpm at 1000 RPM that can be ordered with this PTO as a single part number. Continuous operation is supported with a 30% de-rating applied.
