NOTE
Do not move the connecting rod and crankshaft during clearance measurement.
Remove the connecting rod big end again, measure each clearance between the bearing insert and crankpin [A] using plastigage (press gauge) [B].
NOTICE
After measurement, replace the connecting rod bolts and nuts.
Connecting Rod Big End Bearing Insert/Crankpin Clearance
Standard: 0.030 0.060 mm
(0.0012 0.0024 in.)
Service Limit: 0.10 mm (0.0039 in.)
If the clearance is within the standard, no bearing replacement is required.
If the clearance is between 0.061 mm (0.0024 in.) and the service limit (0.10 mm, 0.0039 in.), replace the bearing inserts [A] with inserts painted blue [B]. Check insert/ crankpin clearance with the plastigage. The clearance 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.
