Using a dial indicator to align the connecting rod before machining is essential for ensuring accuracy in the final dimensions and surface finishes. It helps detect any misalignment, bends, or eccentricities in the rod, ensuring that both the big end and small end are concentric and straight. Proper alignment before machining prevents uneven wear, ensures precise fits with the crankshaft and piston, and contributes to the rod’s balance and overall engine performance. #manualmachinist #engine #ma
