The PACCAR PX-7 and Cummins ISB (specifically the 6.7L variant) are essentially the same medium-duty diesel engine. PACCAR—the parent company of Kenworth and Peterbilt—brands this Cummins-built engine as the PX-7. They share identical internal components, parts, and performance metrics, but have different exterior paint and minor branding. Key Identical Specs Displacement: 6.7 liters Configuration: Inline 6-cylinder Horsepower Range: 200 to 360 hp Torque Range: 520 to 860 lb-ft (up to \(1,200\) Nm depending on calibration) Important Distinctions Support & Diagnostics: Both engines use Cummins electronic diagnostic software (like Cummins Insite), and you can order the exact same replacement parts through both Cummins dealers and PACCAR (Kenworth/Peterbilt) dealerships. Exterior Layout: Because of how they are integrated into specific truck chassis, you might find minor accessory differences like a differently positioned fuel pump, oil pan size, or bracket placements. Reputation: Both platforms suffer from common modern diesel ailments if not maintained perfectly, particularly with EGR (Exhaust Gas Recirculation) and DPF (Diesel Particulate Filter) carbon buildup. Since the PX-7 is a rebranded Cummins ISB, maintenance, parts sourcing, and repairs are interchangeable, making the ownership experience highly similar.
