Crankshaft and Connecting Rods
If clearance is within the standard, no bearing replace-
ment is required.
If clearance is between 0.057 mm (0.0022 in.) and the
service limit (0.09 mm, 0.035 in.), replace the bear-
ing inserts [A] with inserts painted blue [B]. Check
insert/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 crankpin.
51.981 ∼ 52.000 mm (2.0465 ∼ 2.0472 in.)
Service Limit: 51.97 mm (2.0461 in.)
If any crankpin has worn past the service limit, replace the
crankshaft with a new one.
If the measured crankpin diameter [A] is not less than the
service limit, but do not coincide with the original diameter
marking on the crankshaft, make new mark 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 bolts to the specified
torque (see Connecting Rod Installation).
The mark already on the big end should almost coincide
with the measurement because of little wear.
