The Parker Chelsea 823 Series is an 8-bolt power take-off (PTO) designed for high-torque, heavy-duty applications. Featuring a high-strength cast iron housing and extra-wide gears, it delivers up to 750 lb-ft of intermittent torque. Available in a variety of high-speed ratios, heavy-duty bearings, and output shaft options, it is suitable for heavy-duty drivetrains such as Allison and Eaton Fuller. For more technical details, please visit the Parker website.
Maximum Torque Capacity: Delivering up to 750 lb-ft of intermittent torque, the 823 Series is built to handle the highest structural stresses found in commercial truck work without breaking teeth.
Extra-Wide Spur Gears: Features wide-face, precision-ground spur gears that distribute the internal torque load over a much larger surface area, dramatically reducing gear wear and teeth pitting.
Reinforced Cast Iron Housing: The heavy-wall cast iron construction provides superior rigidity, preventing housing flex under sudden shock loads or high vibrations common in extreme-duty work environments.
Large-Diameter Output Shafts: Built with oversized output shafts supported by high-capacity tapered roller bearings to easily withstand high bending and overhung loads from driveshafts or heavy direct-mounted pumps.
Comprehensive Output Adaptability: Provides direct mounting options for large SAE C pumps or companion flanges, eliminating the need for separate external adapter kits and lowering installation costs.

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.
823 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.
A: The 823 Series is a specialized "extra heavy-duty" unit. It uses much wider gear profiles and a beefier internal shaft arrangement compared to the 680 Series, giving it a torque limit of 750 lb-ft, whereas standard 8-bolt PTOs usually top out around 300 to 400 lb-ft.
A: Due to the massive heat generated by transferring up to 750 lb-ft of torque, a pressure lubrication line connected to the vehicle transmission is highly recommended and often mandatory for long-duration or heavy-duty pump operations to prevent bearing failure.
A: Yes. The unit supports various direct-mount pump options including SAE C 2 or 4-bolt configurations. However, because large piston pumps are exceptionally heavy, it is highly recommended to use an external support bracket attached to the truck transmission case to protect the PTO housing from cracking under vibration.
A: No. The standard air-shift versions must be engaged and disengaged while the vehicle is completely stationary, with the air brakes set and the main transmission in neutral. Attempting to shift while moving will cause catastrophic gear failure.
A: A complete Chelsea code (e.g., 823XBAHX-C3XV) requires precise details about your setup. You must match the transmission gear pitch code, select the proper internal speed ratio, choose the shift method, and define the output shaft style based on the pump or driveshaft you intend to connect.
