Inspection
1. Measure the basic bore of the connecting rod bearing.
Notice
If the basic bore exceeds the value of 51.614mm, replace
the bearing or check the connecting rod.
2. Check connecting rod bolts.
3. Check the assembly mark(indication//or number:arrow) of
the connecting rods and the bearing cap when installing.
Notice
lMake sure it doesn’t exceed over 4g with other
connecting rods when replacing the connecting rods.
lCheck if the connecting rod and the bearing cap are
accurately seated on the groove when replacing the
bearing. Notice
If the length exceeds max. length, replace it.
