The Parker Chelsea 660 Series Power Take-Off (PTO) is a legendary, ultra-reliable 6-bolt mechanical shift PTO engineered for heavy-duty manual and automated manual transmissions. Operating as a baseline standard for mechanical transmission upfits, the 660 Series utilizes a rugged, dual-cone or single-gear countershaft architecture designed to deliver continuous, high-torque power. By trading complex internal electric clutch packs for a solid manual cable, lever, or pneumatic shift fork engagement, it eliminates potential electrical short circuits, offering exceptional durability for heavy vocational trucks that require a reliable, mechanical hydraulic drive.
Bulletproof Mechanical Engagement: Built with simple, rugged internal shifting forks. Because it bypasses internal hydraulic clutch friction plates, there are no electronic relays or internal discs to wear out, ensuring maximum mechanical reliability in extreme operating conditions.
Rugged Ductile Iron Structural Housing: The entire chassis is cast from premium ductile iron. This heavy-duty metal provides exceptional rigidity, minimizing housing flex and preventing gear teeth misalignment when supporting bulky, overhung hydraulic gear pumps.
Constant Mesh Conversion Options: Can be ordered or converted into a true Constant Mesh (Non-Shiftable / Live Drive) layout. This permanent gear engagement loop ensures immediate, non-stop power directly proportional to engine RPM, ideal for continuous transport fuel pumps.
Flexible Shift Customization: Features an adjustable internal architecture where the shifting linkage can be positioned on either side of the housing. This allows installers to route manual cables cleanly around tight truck crossmembers and frame rails.

Applications
Fire and Rescue Vehicles : Provides immediate, high-horsepower engagement under load to drive high-volume water pumps and aerial ladders.
Dump Trucks & Trailers : Operates the large hydraulic cylinders needed to raise and lower heavy dump beds quickly and safely.
Cranes & Boom Trucks : Supplies smooth, continuous hydraulic flow for precise control of telescopic booms and outriggers.
Vacuum & Sewer Cleaner Trucks : Runs high-capacity vacuum pumps and high-pressure water jetters for municipal and industrial cleanup.
Fuel & Chemical Tankers : Drives product pumps to safely offload bulk liquids and hazardous materials.
660 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: No. Because it is a mechanical shift PTO utilizing physical gear engagement sliding teeth, the vehicle must be completely stopped and the main transmission clutch pedal depressed before shifting the PTO. Attempting to shift while moving will cause violent gear grinding and instant internal gear damage.
Answer: The 660 uses manual shift forks to slide mechanical gears together, requiring the vehicle to be stopped with the transmission clutch pressed to engage. A hot shift PTO utilizes internal fluid-pressurized wet clutch packs, allowing operators to flip a switch and engage the system immediately while driving or idling.
Answer: It depends on your selected configuration code. If ordered with a Pressure Lube (P) layout, you must route the high-pressure line to the PTO casing. If ordered as a standard Splash Lube (X) variant, it relies entirely on the oil splashed up by the main transmission gears, meaning no external lines are needed.
Answer: Yes. While it is highly popular for direct-mounting hydraulic gear pumps, you can specify the output with a 1-1/4" round keyed shaft or a 1410 Series Companion Flange. This allows you to connect a mechanical universal-joint driveshaft straight to mid-ship mounted tools or water pumps.
Answer: Traditional mechanical shift cables can become stiff, bind, or stretch over time due to dirt and road grime. Upgrading to the Pneumatic (Air) shift option replaces the cable with a sealed air line, allowing the operator to engage the PTO via a clean, effort-free air toggle switch on the vehicle's dashboard.
