Hi,

Can anyone share with me what could be the worse that could happen if the connecting rod bolts on a G3600 series engine were to be tightened unevenly or at a higher/lower than recommended torque values?

Thanks.

Worst case is that it may end in a failure.  Improper rod bolt torquing may lead to one or more bolts not being properly tensioned and possibly loosening. It can also lead to one bolt carrying excessive load, causing it to fail.

OK. Can this lead to any effect on big end pin & bearing.

Not usually, but possible if the big end bearing is getting loose and hammering, the impact forces can get transmitted to the small end. Depends on how long the failure takes to progress to generate downstream related damage. If the big end bearing is badly beaten and extruded, you could see localized damage on the small end.

Is this a generic question or do you have a recent failure with details you can share?
