Engine Connecting Rod Assembly Section drawing with Brass Bearings

This technical drawing depicts a complete engine connecting rod assembly with detailed cross-sectional views. The assembly consists of six primary components: the main connecting rod (FS material), cap (FS material), bearing bush (phosphor bronze), bearing brass inserts (GM material), and fastening hardware (M6 bolts and nuts, MCS material). The drawing features a comprehensive Section A-A view that reveals the internal bearing configuration with dimensional specifications. Key measurements include a 19mm diameter bearing bush and a 22mm outer dimension. The assembly design employs a classic split-cap configuration secured by M6 bolts, allowing for maintenance access to the bearings. The bearing surfaces utilize brass and phosphor bronze materials for their low-friction properties and durability under high-temperature, high-pressure engine operating conditions. The connecting rod body features precise radii transitions to minimize stress concentration points where fatigue failure typically occurs in engine applications.
