2) Next, check bearing cap bore diameter with-
out bearing.
On mating surface of cylinder block, five
alphabets are stamped as shown in Fig.
3-5-46.
Three kinds of alphabets (“A”, “B” and
“C”) represent following cap bore diameters.
The first, second, third, fourth and fifth (left
to right) stamped alphabets indicate the cap
bore diameter of bearing caps
“4” and “5” respectively.
For example, in Fig. 3-5-46, the first (leftmost)
alphabet “B” indicates that the cap bore dia. of
bearing cap is within 49.006 49.012 mm,
and the fifth (rightmost) alphabet “A” indicates
that the cap bore dia. of cap is within 49.000
49.006 mm.
