The Parker Chelsea 852 Series PTO is a heavy-duty 8-bolt PTO designed for high-torque operating environments. Featuring a robust cast iron housing and reinforced internal components, it delivers exceptional power output to heavy equipment at the rear of trucks. This series is specifically optimized for heavy-duty dump trucks, fire trucks, sanitation garbage trucks, and oilfield vehicles, and is widely compatible with mainstream manual and automatic transmissions such as Allison and Eaton Fuller.
High Torque Performance : Delivering up to 500 lb-ft of intermittent torque, the 852 Series bridges the gap between standard 8-bolt PTOs and massive extra-heavy-duty units, handling heavy oilfield and construction loads with ease.
Superior Gear Design : Built with precision-ground, wide-faced gears that reduce tooth pressure and minimize wear, ensuring long-lasting gear mesh and quieter operation under full load.
Rugged Tapered Cone Bearings : Utilizes heavy-duty tapered roller bearings on the output shaft rather than standard needle bearings. This allows it to absorb massive axial and radial thrust loads from direct-mounted hydraulic pumps.
Flexible Direct Mounting : Supports popular SAE B and SAE C direct pump mounting configurations, which helps eliminate expensive intermediate driveshafts and reduces the overall footprint under the truck.
Cast Iron Reliability : The heavy-duty cast iron body ensures minimum casing distortion under severe torsional stress, preventing internal alignment issues and fluid leaks.

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.
852 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 852 Series is primarily used on medium-to-heavy vocational trucks that operate high-capacity equipment. Common applications include heavy-duty dump trucks, refuse cranes, large product pumps, and large winches that require more torque than standard 300 lb-ft class PTOs can handle.
A: It depends on your duty cycle. For short, intermittent tasks (under 15–20 minutes), splash lubrication is usually sufficient. However, for continuous applications like running product pumps or bulk blowers at high torque, a pressure lubrication line connected to the transmission is required to prevent overheating.
A: Yes, it supports direct SAE B and SAE C pump flanges. However, due to the high weight of large piston pumps, you should always install an external support bracket from the pump to the transmission case to prevent vibrations from cracking the PTO housing.
A: No. The standard air-shift and cable-shift versions of the 852 Series must be engaged and disengaged while the truck is completely stationary, with the parking brakes locked and the main transmission shifted into neutral.
A: You need to collect specific details about your truck's layout. You must match the transmission gear pitch code (e.g., Allison or Eaton), choose an internal gear ratio that matches your required tool speed, select your shift method (Air or Electric), and specify the exact pump output flange.
