Best connecting rod bearings.

Bearings clearance basics best bearings one of the abilities that separates the experienced engine builders from the novices is properly fitting the bearing clearances for both the crank and rod. Proper housing bore size and cap fastener torque will ensure that the bearing is properly crushed for maximum retention. Upper main shells which see less loads than the lowers have retained a groove to supply the connecting rods with oil. The most commonly used materials in crankshaft bearings are aluminum copper lead and tin.

And they are all on a comparative basis much softer than the iron and steel crankshafts that run against them. Most rod and main bearings run best with 0007 to 001 of clearance for every inch of crankshaft journal diameter or 0015 to 002 inches of oil clearance for a 2 inch diameter shaft but these numbers will vary with the oil viscosity and application. In reality the right way to check bearing clearances is with the proper tools. Obviously there are others say experts but these are the primary elements that are used.

In order to check the clearances for rod and main bearings you need a set of micrometers and a dial bore gauge these are readily available at budget prices but if you are going to use them a lot better quality tools are advised.
