Important: The color code is on the edge of the bearing. When using bearing halves of different colors, it does not matter which color is used in the top or bottom position. *As the numbers increase, the crankshaft journal diameter decreases and the bearing thickness increases. **As the letters or numbers increase, the main journal bore diameter increases and the bearing thickness increases. |
