The Parker Chelsea 249 Series Power Take-Off (PTO) isa landmark, standard-setting PowerShift direct-mount PTO engineered explicitly for Ford Super Duty trucks equipped with the Ford TorqShift™ 6-speed automatic transmission (6R140). Mounted on the transmission's left/driver-side opening, the 249 Series bridges the gap between light utility demands and heavy-duty reliability. It features a compact, integrated housing that provides exceptional frame clearance while delivering robust torque capacity, making it one of the most widely utilized configurations for vocational work trucks built on Ford chassis.
Seamless Direct-Pump Mounting Space : Engineered with Chelsea's patented integrated housing concept . This design eliminates the need for bulky adapter brackets, allowing a wide array of hydraulic gear pumps to bolt directly to the PTO without striking the Ford frame rail.
Failsafe Electro-Hydraulic Engagement : Utilizes an integrated internal clutch pack activated by an electric 12V solenoid valve . This allows operators to engage or disengage the PTO smoothly at a normal engine idle, minimizing sudden drivetrain shock.
Advanced Constant-Pressure Lubrication : Built with internal oil channels that interface with the transmission's pressure grid. Continuous fluid flow keeps the internal bearings, gears, and pump splines cooled, completely preventing fretting corrosion and gear welding during long operating hours.
Maximized Chassis Payload Protection : Constructed with high-strength ductile iron components optimized to shed unnecessary bulk. At just 31 lbs, it minimizes front-axle overhang weight, helping fleets maintain maximum legal vehicle payload capacity.

Applications
Light-to-Medium Towing & Recovery : Drives hydraulic gear pumps to smoothly operate rollback flatbeds, wheel-lifts, and mid-sized utility recovery winches.
Utility & Bucket Trucks : Provides steady fluid management to run high-reaching aerial boom platforms, bucket lifts, and hydraulic tools for line workers.
Service & Mechanics Rigs : Supplies reliable power to direct-drive screw air compressors, tool-bed cranes, and auxiliary electric generators.
Snow & Ice Control Platforms : Drives multi-section hydraulic systems to manage continuous front snowplow angling and rear salt spreaders.
249 PTO are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
Answer : It is designed strictly for Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the TorqShift™ 6R140 6-speed automatic transmission featuring the factory PTO prep option. It is not compatible with older 5-speed TorqShift or newer 10-speed 10R140 transmissions.
Answer : Yes. Because the Ford 6R140 transmission utilizes an engine-driven gear tied directly to the torque converter impeller hub, the Chelsea 249 can operate whether the vehicle is completely stationary or driving down the highway , which is critical for snowplowing and street sweeping.
Answer : Yes. The 249 Series relies entirely on a Pressure Lube (P) circuit . You must install the high-pressure hose line between the specific pressure port on the Ford transmission housing and the inlet port on the PTO body to ensure constant bearing lubrication and prevent immediate internal gear seizure.
Answer : No. The Chelsea 249 is engineered specifically to interface with the left-hand (driver-side) 6-bolt aperture on the Ford 6R140 transmission. If your application strictly requires a passenger-side mounting configuration, you would need to evaluate a different transmission layout.
Answer : The Wet Spline configuration allows transmission fluid to flow around the mating splines of the PTO output shaft and the hydraulic pump input shaft. This continuous lubrication path eliminates fretting corrosion caused by metal-on-metal friction , making it significantly easier to remove or service the pump years down the road.
