2. Adjust:
●
Main-bearing oil clearance
NOTE:
Adjust the main-bearing oil clearance at
room temperature (20˚C (68 ˚F)).
Adjusting steps:
●
Subtract the crankshaft journal diame-
ters (#1 ~ #5) from the cylinder block
journal diameters (#1 ~ #5).
●
Select the suitable bearing from the
table below according to the calcu-
lated values.

CAUTION:
Remove any oil or dust from the cylinder
block and crankcase bearing mounting
surfaces.
NOTE:
The cylinder block journal diameters (#1 ~
#5) and the crankshaft journal diameters,
(#1 ~ #5) can be determined by the
stamped value as described below.
Crankshaft journal diameter = 47.900 +
(stamped value/1000)
Example: #1 = 92
→
47.992
Cylinder block journal diameter = 54.000
+ (stamped value/1000)
Example: #1 = 32
→
54.032
