ABSTRACT:
An improved bearing assembly which may only be assembled when its principle components are properly fitted together is disclosed herein. Generally, the bearing assembly includes a saddle member and a bearing cap, each of which includes a main bearing receiving, semi-circular recess for journaling the crankshaft of an internal combustion engine. The recess of the saddle member is flanked on either side by first and second alignment slots, and the recess of the bearing cap is flanked by first and second mounting shoulders which are asymmetrical in shape with respect to the axis of rotation of the semi-cylindrical recess, and which are insertable within the first and second alignment slots of the saddle member, respectively. However, dissymmetry between the first and second shoulders prohibit the first shoulder from being inserted into the second alignment slot in a manner to cause proper alignment of the semi-cylindrical recesses. In the preferred embodiment, the shoulders are both generally rectangular in shape, with one shoulder being longer than the other.
