3) There are 5 kinds of standard bearings differing in thickness.
To distinguish them, they are painted in following colors at
the position as shown in the figure.
Each color indicates the following thickness at the center of
bearing.
Standard size Main bearing thickness :
4) From number stamped on crank webs at its center and
alphabets stamped on crankcase lower side, determine new
standard bearing to be installed to journal, by referring to
table shown below.
For example, if number stamped on crank webs is “1” and
alphabet stamped on crankcase is “B”, install a new standard
bearing painted in “Black” to its journal.
New standard size bearing specification :
5) Using gaging plastic, check bearing clearance with newly
selected standard bearing.
If clearance still exceeds its limit, use next thicker bearing
and recheck clearance.
6) When replacing crankshaft or cylinder block and crank case
due to any reason, select new standard bearings to be
installed by referring to number stamped on new crankshaft
or alphabets stamped on new crankcase lower side.Color painted Bearing thickness

•UNDERSIZE BEARING (0.25 mm) :
0.25 mm undersize bearing is available, in 5 kinds varying in
thickness.
To distinguish them, each bearing is painted in the following
colors at such position as shown in the figure.
Each color represents the following thickness at the center of
bearing.

•If necessary, regrind crankshaft journal and select undersize
bearing to use with it as follows.
1) Regrind journal to the following finished diameter.
Finished journal diameter :
64.738 – 64.756 mm (2.5487 – 2.5494 in.)
2) Using micrometer, measure reground journal diameter.
Measurement should be taken in 2 directions perpendicular
to each other in order to check for out-of-round.
3) Using journal diameter measured above and alphabets
stamped on lower crankcase, select an undersize bearing by
referring to table given below.
Check bearing clearance with newly selected undersize
bearing.

General Description
WIRE COLOR SYMBOLS
There are two kinds of colored wire used in this vehicle. One is
single-colored wire and the other is dual-colored (striped) wire.
The single-colored wire uses only one color symbol (i.e. “GRN”).
The dual-colored wire uses two color symbols (i.e. “GRN/YEL”).
The first symbol represents the base color of the wire (“GRN” in
the figure) and the second symbol represents the color of the
stripe (“YEL” in the figure). Symbol Wire Color Symbol Wire Color
