The Chelsea 252 Series Power Take-Off, part number 252GDHVX-B51129 or 252GDHVXB51129, is a hydraulic-shift PTO built for Allison 1000/2000/2400 series automatic transmissions and RAM truck applications. It mounts via a 6-bolt pattern and delivers output through a 1-inch round shaft with key. Intermittent torque falls in the 101-200 lb-ft range (check application pages for the actual rating for your chassis). Shaft power is rated at 11 HP at 500 RPM and 23 HP at 1000 RPM, with output capped at 25 HP. The integrated cartridge valve and single-hose 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 transmission and chassis.
The Chelsea 252 Series is designed for aerial, vocational and municipal equipment, tow and recovery, tire service trucks, and dump truck applications. The compact housing slips through a floor access panel without requiring exhaust system removal, reducing installation time. A range of Parker pump options is available separately, with flows from 1.6 gpm to 8.2 gpm at 1000 RPM, and the PTO and pump can be ordered together as a single part number.
