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”) represent following
cap bore diameters.
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 49.006 – 49.012 mm
(1.9294 – 1.9296 in.), and the fifth (rightmost) alphabet “A” indi-
cates that cap bore dia. of cap “5” is within 49.000 – 49.006 mm
(1.9291 – 1.9294 in.).
3) There are five kinds of 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 bear-
ing.
