Abstract: A method for manufacturing an engine includes the steps of: casting a side skirt having first and second opposing sidewalls and casting a transverse wall of the cast material connecting the sidewalls. The transverse wall will form a bulkhead and a main bearing cap. A first void and a second void are cast into the transverse wall on opposite lateral sides of a main bearing journal location, each void adjacent to one of the sidewalls. A main bearing journal hole is then machined into the transverse wall. Cast material is removed along a first removal path from the edge of the transverse wall and ending into the first void, and along a second removal path from the edge of the transverse wall and ending into the second void. A tool exerts an opening force within the circular bore to fracture the cast material along the first and second fracture planes to separate the main bearing cap from the bulkhead.

Abstract: A lift bracket (300) includes a topmost portion (304) having an opening (302) arranged for engagement with an engagement portion of a lifting apparatus. The topmost portion (304) is substantially flat and defines a first plane (A-A). A base portion (320) of the lift bracket (300) has at least one fastener opening (322) for fastening the base portion to the engine. The base portion (320) also lies in the first plane (A-A). A yield structure (305) is disposed between the topmost portion (304) and the base portion (320), and includes a mid-portion (312) that defines at least one second plane (B-B) that is spaced and parallel to the first plane (A-A). When a tensile force is applied to the topmost portion (304), the yielding structure (305) yields, the topmost portion displaces away from the base portion (320), and the second plane (B-B) displaces towards the first plane (A-A).

Abstract: An automotive engine is provided with an improved multifilter oil lubrication system. At least two filters are provided wherein the majority of the oil flow is through a primary coarse filter. At least one fine secondary filter is provided to filter the oil not going to the coarse filter. The oil from the fine filter is delivered directly to the engine. The improved system may be used with a smaller pump using less horsepower than previously possible by multifilter bypass systems. The addition of the fine filtration increases engine life.
