Engines built from 2010 onward also include a Number
Code next to the Paint Dot. The coding corresponds to the
correct Needle bearing size. (Approx 0.0003" [0.008mm]
graduation between each size)

Blue (#1) is the smallest and Green (#5) is the largest.
Connecting rods with a Red (#3) dot are most common.
