2) Next, check crankshaft pin diameter. On crank web No.3, four alphabets are stamped as shown in the
figure.
Three kinds of alphabet (“A”, “B” and “C”) represent
the following crankshaft pin diameter respectively.
For example, stamped “A” indicates that
corresponding crankshaft pin diameter is 41.994 –
42.000 mm (1.6533 – 1.6534 in.).

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 the
figure.
Each color indicated the following thickness at the
center of bearing.

4) From number stamped on connecting rod and its cap and alphabets stamped on crank web No.3,
determine new standard bearing to be installed to
connecting rod big end inside, by referring to the
table.
For example, if number stamped on connecting rod
and its cap is “1” and alphabet stamped on crank
web No.3 is “B”, install a new standard bearing
painted in “Black” to its connecting rod big end
inside.
