The connecti ng rods are manufactured from forged s teel wi th an 'I' beam shaft cons truct ion t o provi de high s t rength anddurabil it y. The connect ing rod s mall -end i s narrowed on each s i de to form a tapered head. The taper improves t hedis t ribut ion of force between t he pis t on and connect ing rod duri ng t he combus t ion s troke. A bronze bush is i nst all ed in t hes mall -end, and formed wit h an internal groove t o al low t he flow of l ubricati ng oil around t he bush.
The connecti ng rod bi g-end i s cut and machined at t he joi nt to form a bearing housi ng and bearing cap t hat is s ecured by 2bolt s.
