Connecting Rod Big End Side Clearance Inspection

• Measure connecting rod big end side clearance.

Insert a thickness gauge [A] between the big end and either crank web to determine clearance.

Connecting Rod Big End Side Clearance

Standard: 0.13 0.38 mm
(0.0051 0.0150 in.)

Service Limit: 0.58 mm (0.023 in.)

If the clearance exceeds the service limit, replace the connecting rod with new one and then check clearance again.

If the clearance is too large after connecting rod replacement, the crankshaft also must be replaced.
