Abstract:
The present invention provides a PM main bearing cap, and its precursor compact, with an undercut breathing window that is formed during a compaction process. By fabricating the undercut during the compaction process, the invention eliminates the need for a secondary machining operation to form the undercut feature in the bearing caps.
