The Chelsea 249GMLLX-B237 or 249GMLLXB237 is a Power Take-Off assembly from the Chelsea 249 Series, designed specifically for Ford Super Duty trucks equipped with the Ford 6R140 TorqShift 6 automatic transmission. It mounts via a 6-bolt Ford pattern and uses hydraulic (PowerShift) actuation with a single hose connection and an integrated cartridge valve, simplifying installation and reducing leak points. The 249 Series carries a series intermittent torque rating up to 200 lb-ft (271 Nm) and is engineered with Chelsea's patented noise-suppression system, making it the only PTO in its class to reduce torsional noise on this transmission platform. Available for both 2WD and 4WD applications, it fits work truck uses including service trucks, tow and recovery, small dump trucks, and aerial or fire and rescue equipment.

Additional Information
The Chelsea 249 Series uses an internal pressure lube system (denoted by "X" in the part number suffix) and supports continuous operation with a 30% de-rating applied. Output shaft options across the 249 Series include a 1-1/4" round shaft with 5/16" key (including Smart Start variants), 3/4"-11T pump spline, and SAE B (7/8"-13T) pump spline. Output types available in the series are driveline and SAE A pump flange. The 249 Series also features an integrated pressure switch alongside the cartridge valve, which reduces the number of external components required during installation.
