Crankshaft bearing cap bore diameter specification
Stamped alphabets on lower crankcase represent crankcase bore
diameter marked with an arrow in figure respectively.
For example, stamped alphabet “A” at bearing cap No.2 indicates
that bearing cap bore diameter of bearing cap No.2 is 62.0000 –
62.0060 mm (2.4409 – 2.4411 in.).
3) There are five kinds of standard bearings differing in thick-
ness. To distinguish them, they are painted in following col-
ors at the position as indicated in figure.
Each color indicated the following thickness at the center of
bearing.
