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 the follow-
ing cap bore diameters.
Alphabet stamped
Bearing cap bore diameter
(without bearing)
A
49.000 – 49.006 mm
(1.9291 – 1.9294 in.)
B
49.006 – 49.012 mm
(1.9294 – 1.9296 in.)
C
49.012 – 49.018 mm
(1.9296 – 1.9298 in.)
The first, second, third, fourth and fifth (left to right) stamped al-
phabets reperesent 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, and the fifth (rightmost) alphabet “A” indicates that cap bore
dia. of cap “5” is within 49.000 – 49.006 mm.
3) There are five kinds of standard bearings differing in thickness.
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.
Color painted
Bearing thickness
Green
1.996 – 2.000 mm
(0.0786 – 0.0787 in.)
Black
1.999 – 2.003 mm
(0.0787 – 0.0788 in.)
Colorless
(no paint)
2.002 – 2.006 mm
(0.0788 – 0.0789 in.)
Yellow
2.005 – 2.009 mm
(0.0789 – 0.0790 in.)
Blue
2.008 – 2.012 mm
(0.0790 – 0.0791 in.)
