A method of making a powder metal bearing support insert includes filling a tool and die set with a powder metal. A compact is compacted from the powder metal using the tool and die set in which the compact includes a body having a pair of opposing ends on lateral sides thereof, a bearing-receiving surface positioned on a side of the body between the pair of opposing ends in which the bearing-receiving surface is for reception of a bearing therein, and a pair of holes extending through the body wherein each of the pair of holes are formed by sets of adjacent interdigitated slots having regions that abut one another to form a connected passageway therethrough that define the respective hole. The compact is sintered to form the powder metal bearing support insert. The powder metal bearing support insert may be cast into an engine component.

Method of forming a powder metal insert having a horizontal through hole and method of casting same into an engine component

A powder metal bearing support insert for casting into an engine component includes a pair of holes formed by interdigitated slots during a powder metal compaction process. Since they are formed by interdigitated slots, this pair of holes may receive the cast material therein during the casting step. Among other things, the cast material in these holes may be drilled or machined using tools graded to work the material of the casting in contrast to the material of the insert.

Method of forming a powder metal insert having a horizontal through hole

A bearing cap in which each foot includes a protrusion formed thereon that is generally linear having opposing sides in which each of these opposing sides support a plurality of crush ribs.

Main bearing cap with locating feature

A bearing cap () in which each foot includes an elongated protrusion () formed thereon positioned between the bolt hole and a side of said foot, with its major axis parallel to the axis of the bore partially defined by the bearing cap and includes ribs on its side surfaces that are perpendicular to its major axis.
