Main Bearing Selection

Block Bore Code Location

Numbers, letters, or bars have been stamped on the end of the block as a code for the size of each of the five main journal bores.

Use them, and the numbers or bars stamped on the crankshaft (codes for main journal size), to choose the correct bearings. If the codes are indecipherable because of an accumulation of dirt and dust, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.
