Selection of main bearings
STANDARD BEARING:
If engine is under the following conditions, select a new
standard bearing as followings and install it.
• Bearing is in malcondition.
• Bearing clearance is cut of specification.
• Crankshaft or cylinder block is replaced.
1) First check journal diameter. As shown in figure,
crank web No.2 has stamped numbers.
Six kinds of numbers ("4" through "9") represent the
following journal diameters.
Journal diameter
Stamped numbers
4
5
6

9
Stamped numbers on crank web No.2 (3) represent
journal diameters marked with an arrow in figure
respectively. For example, stamped number "5"
indicates that corresponding journal diameter is
58.0000 – 58.0029 mm (2.28346 – 2.28357 in.).

2) Next, check journal bore diameter. On lower
crankcase five alphabets are stamped as shown in
figure.
Three kinds of alphabets ("A", "B" and "C") represent
the following journal bore diameters.

Stamped alphabets on lower crankcase represent
journal diameter marked with an arrow in figure
respectively.
For example, stamped alphabet "A" at No.2 journal
indicates that (journal) bore diameter of No.2 journal
is 62.0000 – 62.0060 mm (2.44094 – 2.44117 in.).

3) There are 5 kinds of standard bearings differing in
thickness. To distinguish them, they are painted (1)
in the following colors at the position as indicated in
figure.
Each color indicates the following thickness at the
center of bearing.
