2) Next, check bearing cap bore diameter without
bearing. On mating surface of cylinder block, five
alphabets are stamped as shown in the 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 the figure respectively.
For example, stamped "A" or "1" indicates that
corresponding bearing cap bore diameter is 56.0000
– 56.0060 mm (2.2048 – 2.2049 in.).

3) There are 5 kinds of standard bearings differing in
thickness. To distinguish them, they are painted in
the following colors at the position as indicated in the
figure.
Each color indicated the following thickness at the
center of bearing.

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 the table shown.
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.

5) Using scale (1) on gauging plastic (2), check bearing
clearance with newly selected standard bearing.
If clearance still exceeds its limit, use next thicker
bearing and recheck clearance.
6) When replacing crankshaft or cylinder block due to
any reason, select new standard bearings to be
installed by referring to number stamped on new
crankshaft or alphabets stamped on new cylinder
block.
