The Chelsea 252DMKUX-B5P37 or 252DMKUXB5P37 is a 252 Series Power Take-Off assembly built for Allison 1000/2000/2400 series automatic transmissions and RAM truck applications. It uses hydraulic shifting and mounts with a 6-bolt pattern. The 1" round output shaft with keyway delivers up to 23 HP at 1,000 RPM and 11 HP at 500 RPM. Intermittent torque is rated in the 101-200 lb-ft range; check the Chelsea application pages for the confirmed 120 lb-ft figure for your specific installation. Installation is simplified by a single hose connection with an integrated cartridge valve, eliminating remote solenoids and multiple hose runs. Weather-tight electrical connectors and a controlled compression interface gasket are built in. Call us to confirm proper fit for your transmission and chassis.
The 252 Series PTO housing is designed to pass through a floor access panel without requiring removal of the exhaust system, reducing installation time. Compatible Parker pump options with flows from 1.6 gpm to 8.2 gpm at 1,000 RPM are available for this series. The PTO and pump can be ordered together under one part number and ship in one box. Typical applications for the 252 Series include tow and recovery, tire service trucks, dump trucks, and aerial equipment. Part number 252DMKUX-B5P37 is also referenced as 252DMKUXB5P37.
