2) Next, check bearing cap bore diameter without bearing. On
mating surface of cylinder block, five alphabets are stamped
as shown in figure.
Three kinds of alphabets ("A", "B" and "C") or numbers ("1",
"2" and "3") represent the following cap bore diameters.
Stamped alphabets or numbers on cylinder block represent
bearing cap bore diameter marked with an arrow in figure
respectively. For example, stamped "A" or "1" indicates that
corresponding bearing cap bore diameter is 56.000 – 56.006
mm (2.2047 – 2.2050 in.).

C (3) 56.0121 – 56.0180 mm (2.2052 – 2.2054 in.)
3) There are five kinds of standard bearings differing in thick-
ness. To distinguish them, they are painted in the following
colors at the position as indicated in figure.
Each color indicated the following thickness at the center of
bearing.

Purple 1.992 – 1.996 mm (0.07843 – 0.07858 in.)
Brown 1.995 – 1.999 mm (0.07855 – 0.07870 in.)
Green 1.998 – 2.002 mm (0.07867 – 0.07882 in.)
Black 2.001 – 2.005 mm (0.07878 – 0.07893 in.)
Colorless 2.004 – 2.008 mm (0.07890 – 0.07906 in.)

4) From number stamped on crank web No.2 and alphabets
stamped on cylinder block, determine new standard bearing
to be installed to journal, by referring to table shown below.
For example, if number stamped on crank web No.2 is "1"
and alphabet stamped on cylinder block is "B", install a new
standard bearing painted in "Brown" to its journal.
