Selection of Main Bearings
Standard bearing
If bearing is in malcondition, or bearing clearance is out
of specification, select a new standard bearing according
to the following procedure and install it.
1) First check journal diameter. As shown in the figure,
crank web No.2 has stamped numbers.
Three kinds of numbers (“1”, “2” and “3”) represent
the following journal diameters.
Stamped numbers on crank web No.2 represent
journal diameters marked with an arrow in the figure
respectively. For example, stamped number “1”
indicates that corresponding journal diameter is
51.9940 – 52.0000 mm (2.0471 – 2.0472 in.).
Crankshaft journal diameter
2) Next, check bearing cap bore diameter without
bearing. On mating surface of cylinder block, five
alphabets are stamped as shown in the figure.
Three kinds of alphabets (“A”, “B” and “C”) or
numbers (“1”, “2” and “3”) represent the following
cap bore diameters.
Stamped alphabets or numbers on cylinder block
represent bearing cap bore diameter marked with an
arrow in the figure respectively.
For example, stamped “A” or “1” indicates that
corresponding bearing cap bore diameter is 56.0000
– 56.0060 mm (2.2048 – 2.2049 in.).

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