Connecting rod bearings gets great loads of stress and are among the causes of catastrophic engine failure. Very tight or stiff bearing problems can result in many problems. Rod bearings can spin, freeze, stretch, deform and endure out-of-round conditions. Connecting rods bearings have precision, surfaces that must handle in a contamination-free environment when inspection and repair is carried out. Human error, lack of proper lubrication and structural failure add to most bearing failures.
