Warning: When using a steam cleaner, wear protective clothing and safety glasses or a face shield. Hot steam
can cause serious personal injury.
Use a nylon bristle brush to clean the oil drillings.
Use steam or solvent to clean the connecting rods. Dry with compressed air.
Inspect the connecting rods and connecting rod caps for damage.
Replace the connecting rod if the “I-beam ” is nicked or damaged.
Measure the connecting rod piston pin bushing I.D.
Measure the connecting rod crank bore with the bearing shells removed and the capscrews torqued to 100 N*m
[73 ft-lb].
If the crank bore measurements are not within specifications, replace the rod assembly.
Measure the connecting rod crankshaft bore inside diameter with the bearings installed (capscrews torqued to
100 N®m [73 ft-lb].
Measure the diameter of the rod journal on the crankshaft.
Bearing clearance = rod inside diameter (with bearing) minus crankshaft journal diameter.
Bearing clearance can also be determined with plastigauge during engine assembly.
