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 the fol-
lowing cap bore diameters.
Crankshaft bearing cap bore diameter specification
The first, second, third, fourth and fifth (left to right) stamped
alphabets 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 diameter of bearing cap “1” is within 56.0061 –
56.0120 mm (2.2050 – 2.2051 in.), and the fifth (rightmost) alpha-
bet “A” indicates that cap bore dia. of cap “5” is within 56.0000 –
56.0061 mm (2.2048 – 2.2049 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 indicates the following thickness at the center of
bearing.
