Crankshaft and Connecting Rods
If the clearance is within the standard, no bearing replace-
ment is required.
If the clearance is between 0.042 mm (0.00165 in.) and
the service limit (0.08 mm, 0.003 in.), replace the bear-
ing inserts [A] with inserts painted blue [B]. Check in-
sert/crankpin clearance with the plastigage. The clear-
ance may exceed the standard slightly, but it must not be
less than the minimum in order to avoid bearing seizure.
If the clearance exceeds the service limit, measure the
diameter of the crankpins.
37.984 ∼ 38.000 mm (1.4954 ∼ 1.4961 in.)
Service Limit: 37.97 mm (1.4949 in.)
If any crankpin has worn past the service limit, replace the
crankshaft with a new one.
If the measured crankpin diameters are not less than the
service limit, but do not coincide with the original diameter
markings on the crankshaft, make new marks on it.

Measure the connecting rod big end inside diameter, and
mark each connecting rod big end in accordance with the
Tighten the connecting rod big end nuts to the specified
torque (see Connecting Rod Installation).
The mark already on the big end should almost coincide
with the measurement.
