Engine

Using the data recorded earlier and the Bearing Select Fit Chart in the illustration below, Standard Bearings, determine the required bearing grade for main bearings 2 and 3.

Read the second letter of the engine block main bearing code and the second letter of the crankshaft main bearing code.

Read down the column below the engine block main bearing code letter and across the row next to the crankshaft main bearing code letter, until the 2 intersect. This is the required bearing grade for the No. 2 crankshaft main bearing.

As an example, if the engine block code letter is "N" and the crankshaft code letter is "H", the correct bearing grade for this main bearing is "2".

Repeat the above steps using the third letter of the block and crankshaft codes to select the No. 3.
