ABSTRACT:
A method of manufacturing a connecting rod is disclosed, in which a formed body of a connecting rod integrated with a cap section of iron metal powder is heated, before or after being sintered, with a bearing metal ring set in the bearing section thereof. During or after sintering, the bearing metal is infiltrated in the bearing section, followed by the forging as required. Then the cap section is separated. In this way, the manufacturing steps are reduced, while at the same time preventing the bearing section from being overheated and seizured due to an improved heat conductivity between the connecting rod body and the bearing section.
