2) Next, check bearing cap bore diameter without bearing. On mat-
ing surface of cylinder block, four alphabets are stamped as
shown in figure.
Three kinds of alphabets ("A", "B" and "C") represent following
cap bore diameters.
Alphabet stamped
The first, second, third, fourth and fifth (left to right) stamped al-
phabets represent cap bore diameters of bearing caps "1", "2",
"3", "4" and "5", respectively.
For example, in figure, the first (leftmost) alphabet "B" indicates
that cap bore dia. of bearing cap "1" is within 56.006 – 56.012
mm, and the fifth (rightmost) alphabet "A" indicates that cap bore
dia. of cap "5" is within 56.000 – 56.006 mm.
3) There are five kinds fo standard bearings differing in thickness.
To distinguish them, they are painted in following colors at the
position as indicated in figure.
Each color indicates following thickness at the center of bearing.
