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.

4) From number stamped on crank web No.2 and
alphabets stamped on cylinder block, determine new
standard bearing to be installed to journal, by
referring to the table shown.
For example, if number stamped on crank web No.2
is "1" and alphabet stamped on cylinder block is "B",
install a new standard bearing painted in "Brown" to
its journal.

5) Measure main bearing clearance with newly
selected standard bearing referring to "Main Bearing
Clearance" under "Main Bearings Inspection".
If clearance still exceeds its limit, use next thicker
bearing and recheck clearance.
6) When replacing crankshaft or cylinder block due to
any reason, select new standard bearings to be
installed by referring to number stamped on new
crankshaft or alphabets stamped on new cylinder
block.
Undersize bearing (0.25 mm)
• 0.25 mm (0.0098 in.) undersize bearing is available, in
five kinds varying in thickness.
To distinguish them, each bearing is painted in the
following colors at such position as indicated in the
figure.
Each color represents the following thickness at the
center of bearing.
