The Parker Chelsea 680 series is an 8-bolt standard heavy-duty power take-off (PTO) designed specifically for medium and heavy-duty trucks . It is optimized for modern high-torque vocational truck applications and is perfectly compatible with mainstream manual and automatic manual transmissions (AMTs) such as Eaton Fuller , Volvo/Mack , and Detroit/Daimler , finding wide application in hydraulic pumps, blowers, and onboard equipment drives.
Space-Saving Housing : Features a highly compact air-shift cover design that maximizes clearance under the truck chassis, eliminating interference and simplifying installation.
360° Rotatable Flange : The direct-mount pump flanges feature Chelsea's 360-degree rotatable design. This allows the operator to rotate the hydraulic pump to precisely clear chassis frame rails, exhaust systems, or fuel tanks.
Advanced AMT Integration : Offers specialized double-acting air shift mechanisms tailored for modern automated manual transmissions (like Detroit DT12™ and Eaton Endurant™), ensuring positive gear engagement and accident preventingal disengagement.
Modular Versatility : With 32 output arrangements and 10 distinct shift mechanism choices, it can be customized to power virtually any bulk feed blower, product pump, or high-pressure hydraulic system.
| Parameter | Specification / Configuration Options |
|---|---|
| Installation Method | Standard 8-bolt axial mounting; Mack transmission-specific deep mounting housing available |
| Intermittent Torque | 325 lb-ft (441 N·m) |
| Continuous Torque | 228 lb-ft (309 N·m), calculated at 70% of intermittent torque |
| Power Rating @ 1,000 RPM | 62 HP (46 kW) |
| Number of Internal Speed Ratios | Four speed ratios available |
| Output Shaft Configurations | 32 arrangements available, including SAE A/B/C, ISO 7652 direct-mount interfaces, and 1-1/4 in keyed shafts |
| Shift Options | Pneumatic, electro-pneumatic (12 V/24 V), mechanical cable, lever, or double-acting pneumatic shift |
| Lubrication Options | Pressure lubrication or non-pressure lubrication |
| Approximate Weight | 51.5 lb (23.4 kg) |
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.
680 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 primary upgrade is the integration of heavy-duty tapered roller bearings over standard needle bearings, allowing it to withstand much higher axial and radial stresses. Its maximum intermittent torque is rated at 325 lb-ft (441 Nm) , making it ideal for modern high-horsepower vocational trucks.
A : No, it depends on your application. The 680 Series is available in both Pressure Lube (P) and No Pressure Lube (X) configurations. However, for continuous-duty applications (such as running a product blower for more than 30 minutes) or when paired with certain AMTs, pressure lubrication is highly recommended or mandatory to ensure proper cooling.
A : Yes. However, because AMT clutches are computer-controlled, you must specify Chelsea's Double-Acting Air Shift option. This system uses air pressure to both engage and actively disengage the PTO, preventing gear clashing and integration errors with the transmission software.
A : When installing a hydraulic pump directly, the space under the truck is often very limited. Thanks to a 360° rotatable flange, you can adjust the pump to the optimal orientation—easily clearing chassis rails, drive shafts, or exhaust pipes—without the need for complex modifications or remote drive shaft extensions.
A: A complete Chelsea part number (e.g., 680XQAHX-B3XV) is a code representing the exact transmission model, speed ratio, shift type, and output flange. To get the correct number, you must provide your exact transmission model code, the specification of the pump being driven, and your desired output shaft speed.
