The 8.3 Cummins engine, commonly known as the C8.3 or 6CT8.3, is a reliable mid-range diesel engine used in trucks, buses, agricultural equipment, and industrial machinery. One of the most asked-about specifications is its weight.
On average, the 8.3 Cummins engine weighs between 1,500 and 1,650 pounds (680–750 kg), depending on the specific configuration, accessories, and whether it’s a mechanical or electronic version. The dry weight (without fluids) is typically around 1,500 lbs, while the wet weight (with coolant and oil) can be closer to 1,650 lbs.
This moderate weight is a good balance between durability and performance. It allows the 8.3 Cummins to provide excellent torque while remaining suitable for a wide range of medium- to heavy-duty applications. Understanding the engine’s weight is essential when planning vehicle modifications, replacements, or transport logistics.
