ABSTRACT:
An adaptor (ladder frame 10) and oil pan assembly (14), including a method of assembly therefor, is disclosed for mounting on an internal combustion engine block (2) equipped with a lubrication system designed to receive oil for recirculation through an inlet port (22) in the ladder frame (10) offset from the center of the oil pan assembly (14) when the assembly (14) is mounted in one of two reversed positions. The oil pan assembly (14) includes an asymmetrically offset oil pan reservoir (27) and integrally connected sump pipe (28, 48) within the interior of the pan shaped in accordance with the intended position of the oil pan assembly when mounted on the engine. The shape of the sump pipe (28, 48) is selected to provide automatic alignment and connection between the reservoir (27) and the inlet port (22) when the oil pan assembly (10) and sump pipe (28, 48) are simultaneously mounted on the engine. The sump pipe (28, 48) includes, in addition, filter means in the form of slots (62) contained in one leg of the sump pipe. The ladder frame is characterized by an oil pump receiving recess 16 and internalized oil flow passages (20a and 20b) to further reduce assembly costs.
