Piston And Connecting Rod Assembly

The connecting rods have fracture-split bearing caps. The bearing caps are produced by fracturing the opposing sides of the connecting rod at the bearing horizontal centerline. As well as being easier to manufacture, when reassembled the fractured surfaces interlock to form a strong seamless joint. The cylinder position is etched on adjoining sides of the joint to identify matching connecting rods and bearing caps. The connecting rod bearings are selective split plain bearings. The connecting rod bearing is 'bismuth coated tri-metal', which is a manufacturing process that layers the bearing material to produce a higher load capacity for improved durability.
