Throughout this site we use many technical terms, and given the breadth of readership our site enjoys, sometimes we are remiss and incorrectly assume everyone knows what we are referring to. For those that do not, here are some explanations of the technical terms use.
Connecting Rod (colloquially, con-rod)
Rigid H-section forging or casting, usually made from alloy steel, which connects the piston and crankshaft. The cranks aft end terminates in a large split bearing (the big-end bearing) which fits closely round the crankpin, while the upper end includes a much smaller bearing (the little-end, or small-end, bearing) fitting round the gudgeon pin secured to the piston.
