3516B High Displacement EngineThe 3516B high displacement engine provides increased machine performance with less fuel consumption in certain applications. The 3516B high displacement engine uses four identical single stage turbochargers that eliminate the need for a wastegate. There are two pairs of turbochargers on the standard engine. Each pair of turbochargers has a low pressure turbocharger and a high pressure turbocharger. The low pressure turbocharger and the high pressure turbocharger are connected in series. The series arrangement turbochargers require a wastegate in order to regulate the boost pressure. The separate turbochargers of the 3516B high displacement engine do not require a wastegate. The installation of the 3516B high displacement engine requires changes to the parts groups that follow: air inlet tubes, coolant return lines for the turbochargers, tubes for the Separate Circuit Aftercooler (SCAC), air line for the wastegate and VIMS software.Note: If the truck is not equipped with the VIMS system, modifications are required. Refer to Special Instruction, SEHS9829, "Retrofitting a 793B Off Highway Truck with Vital Information Management System".ReferencesDisassembly and Assembly, SENR5676, "793B Truck Engine Supplement"Disassembly and Assembly, SENR5692, "793B Truck Machine Systems"Special Instruction, SEHS9829, "Retrofitting a 793B Off Highway Truck with Vital Information Management System"Read the entire special instruction.
