Weighing apparatuses including positioning fixture assemblies for weighing connecting rods

A positioning fixture assembly comprising:

• a small end fixture assembly comprising
• a small end base structure comprising a base plate that rests on a weighing platform of a first weighing device and a centering member guide structure;
• and
• a small end centering member received by the centering member guide structure of the small end base structure, the small end centering member moves relative to the centering member guide structure of the small end base structure between a retracted configuration and an extended configuration;
• and
• a large end fixture assembly comprising
• a large end base structure comprising a base plate that rests on a weighing platform of a second weighing device and a centering member guide structure;
• and
• a large end centering member received by the centering member guide structure of the large end base structure, the large end centering member moves relative to the centering member guide structure of the large end base structure between a retracted configuration and an extended configuration.

A method of weighing a small end and a large end of a connecting rod, the method comprising:

• placing a first weighing device including a weighing platform adjacent a second weighing device including a weighing platform such that the weighing platforms are side-by-side;
• placing a small end fixture assembly on the weighing platform of the first weighing device that supports the small end of the connecting rod thereon at a location spaced above the weighing platform of the first weighing device;
• and
• placing a large end fixture assembly on the weighing platform of the second weighing device that supports a large end of the connecting rod thereon at a location spaced above the weighing platform of the second weighing device.
