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
l
Make sure it doesn’t exceed over 4g with other
connecting rods when replacing the connecting rods.
l
Check if the connecting rod and the bearing cap are
