2) Next, check bearing cap bore diameter without bearing. On low-
er crankcase, five numerals are stamped as shown in figure.
Three kinds of numerals ("1", "2" and "3") represent following
cap bore diameters.
Stamped numerals on the inside of lower crankcase represent
bearing cap bore diameter marked with an arrow in figure re-
spectively.
For example, stamped number "1" indicates that corresponding
bearing cap bore diameter is 49.000 – 49.006 mm.
Should numbers be defaced and unreadable, measure bearing
cap bore diameter.
3) There are five kinds of bearings differing in thickness. To distin-
guish them, they are painted in following colors at the position
as indicated in figure.
Each color indicates following thickness at the center of bear-
ing.
