Aerio L4-2.3L (2006)
6: 57.9970 - 57.9999 mm (2.28334 - 2.28345 inch)
7: 57.9940 - 57.9969 mm (2.28323 - 2.28333 inch)
8: 57.9910 - 57.9939 mm (2.28311 - 2.28322 inch)
9: 57.9880 - 57.9909 mm (2.28299 - 2.28310 inch)
Stamped numbers on crank web No.2 (3) represent journal diameters marked with an arrow in figure respectively. For example, stamped number
"4" indicates that corresponding journal diameter is 58.0030 - 58.0060 mm.
2) Next, check crankcase (bearing cap) bore diameter without bearing. On lower crankcase five alphabets are stamped as shown in figure.
Three kinds of alphabets ("A", "B" and "C") represent the cap bore diameters.
Bore diameter for bearing cap No.1, No.2, No.3 and No.5 (without bearing)
A: 61.9940 - 62.0000 mm (2.44071 - 2.44094 inch)
B: 62.0001 - 62.0060 mm (2.44095 - 2.44117 inch)
C: 62.0061 - 62.0120 mm (2.44118 - 2.44141 inch)
Stamped alphabets on lower crankcase represent crankcase bore diameter marked with an arrow in figure respectively.
For example, stamped alphabet "A" at bearing cap No.2 indicates that bearing cap bore diameter of bearing cap No.2 is 61.994 - 62.000 mm.
3) There are 5 kinds of standard bearings differing in thickness. To distinguish them, they are painted (1) in the colors at the position as indicated in
figure. Each color indicates the thickness at the center of bearing.
Standard size main bearing thickness
Green: 1.9910 - 1.9940 mm (0.07839 - 0.07850 inch)
Black: 1.9940 - 1.9970 mm (0.07851 - 0.07862 inch)
Colorless (no paint): 1.9970 - 2.000 mm (0.07863 - 0.07874 inch)
