- 3. Check the connecting rod.
- When reinstalling, check the cylinder numbers on the connecting rods and the caps. When installing a new connecting rod, the notches for bearing fixing on the connecting rods and caps should face the same direction.
- If one or both edge of the connecting rod thrust surface is damaged, replace the rod. If the inner surface of the rod is damaged or rough, also replace it.
- Using a connecting rod aligner, measure the bent or torsion of the rod. If the measurement is near the specification, adjust the rod with a press. If the rod is bent or twisted excessively, replace it.
Allowable bend of connecting rod
0.05mm/100mm (0.0020in./3.9370in.)
Allowable twist of connecting rod
0.1mm/100mm (0.0039in./3.9370in.)
NOTE: When assembling the rod without a bearing, there should be no difference.
