The connecting rod of an engine is one of the most abused and least respected parts. The load and stress it experiences are extreme. For example, the connecting rod must support four to five tons of pressure during combustion. Also, the rod is required to reverse its travel many times a second. As an example, a connecting rod in the average engine running at 3,000 rpm is reversed 100 times in one second. Much of this load is applied to the bolts that hold the rod to the journal. For this reason, new high-quality connecting rod bolts should be installed during any performace-based rebuild. The first step is to press out the old bolts, as seen in this photo.
