KRP3016 064 IEP Conrod Bearing Kit



The connecting rod is best known through its use in internal combustion engines. T is connected by bearings to the piston and the crankshaft. The bearing is a device supporting a mechanical element and providing its movement relatively to another element with a minimum power loss. The rotating components of internal combustion engines are equipped with sleeve type sliding bearings. The reciprocating engines are characterised by cycling loading of their parts including bearings. These loads are a result of alternating pressure of combustion gases in the cylinders. Roller bearings, in which a load is transmitted by balls to a relatively small area of the ring surface, cannot withstand the loading conditions on an internal combustion engine. Only sliding bearings provide a distribution of the applied load over a relatively wide area.

Characteristics of the connecting rod bearings

The connecting rod bearings provide rotating motion of the crankshaft within the connecting rod. This transmits cycling loads applied to the piston. Connecting rod bearings are mounted in the big end of the connecting rod and consist of two halves to facilitate installation. The big end bearings are lubricated by the engine oil that is fed through the crankshaft and forced between the bearing surface and the crankshaft surface. The bearing material must be extremely strong because of the stresses caused by the explosions inside the internal combustion engine. Reducing friction is accomplished in part by the fact that dissimilar metals slide against each other with less friction and wear than similar materials will.

Symptoms of failure of conrod bearings

Replacing the connecting rod bearings timeously can save your engine from expensive repairs. When worn or damaged they can provoke a dull banging noise eventually rising to a hard banging sound. This happens when the big ends have no bearing material to work on. The rod knock is a sure indication that the bearings are failing and need immediate replacement. Failure to do so will result in the engine ripping itself apart and the engine will need to be replaced as the damage can be so severe that repair is not an option.
