The main engine bearings are commonly known as the big end bearings, small end bushes, main bearings, thrust washers and camshaft bushes and bearings. Each of these has an important role to play in the running of the engine. The connecting rod bearings have shells that come in two halves to facilitate installation. The small end bushes are bearings that are located at the smaller end of the connecting rod. The main bearings are located in the engine block where the crankshaft is situated. One half of the shell is located in the engine block and the other in the crank cap. The main bearing may have certain characteristics such as oil holes, locating tags and oil grooves to ensure correct installation and to facilitate adequate lubrication.
Characteristics of a bearing
A bearing kit usually contains all the parts needed to assemble a bearing. Engine bearings have to withstand punishing loads in today’s engines. Smaller displacements, turbocharging and higher horsepower ratings mean crankshaft and connecting rod bearings are being subjected to heavier loads. This has led to manufacturers designing bearings with new alloys and coatings that enable these parts to survive. The connecting rod bearings take the most punishment because of the reciprocating motion of the pistons and conrods. The load on the bearings changes with the crank angle and RPM. It also changes depending on whether the cylinder is on the power stroke, compression stroke, intake stroke or exhaust stroke.
Benefit of using a KRP 3027IEP Bearing Kit
All the necessary parts are in the kit to allow for assemblage of the bearing. The manufacturer has carefully designed the bearing to fit into a certain make and model of engine to ensure the bearing is strong enough to support the load it will be facing. This helps to ensure a longer engine life. Using a cheap copy can lead to catastrophic engine failure and may require a complete engine replacement. The bearing has further been designed to allow for maximum lubrication of the bearing. To order a KRP3027 IEP Bearing Kit, contact IEP Power Products today.
