For example, stamped "A" indicates that
corresponding crankshaft pin diameter is 41.994 –
42.000 mm (1.6533 – 1.6534 in.).

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.
