The Chelsea 252RMKUX-B51449 or 252RMKUXB51449 is a 252 Series Power Take-Off assembly built for Allison automatic transmissions and RAM truck applications. It uses hydraulic shift actuation and mounts via a 6-bolt pattern, with a 1-inch round output shaft with keyway. Shaft power output is rated at 11 HP at 500 RPM and 23 HP at 1000 RPM, with intermittent torque in the 101-200 lb-ft range (verify actual rating on the Chelsea application pages for your specific vehicle). The compact housing was designed to pass through a floor access panel without dropping the exhaust, and the integrated cartridge valve plus single-hose connection simplify installation. Continuous operation is supported with a 30% de-rating. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 252 Series PTO is designed for aerial, vocational, municipal, tow and recovery, tire service, and dump truck applications. The compact housing slips through the floor access panel without requiring the exhaust system to be dropped, reducing installation time. Parker pumps compatible with this series are available with flows from 1.6 gpm to 8.2 gpm at 1000 RPM, and the PTO and pump can be ordered together under a single part number. Part number SP252RMKUXB51449 is an alternate reference for this assembly.
