Connecting Rod Reconditioning

This step of the engine rebuilding is important the fact that the rod is part of the motion of the engine.

After cleaning and then crack checking and straightening the rod we then machine the parting faces of the rod making the bearing end smaller.
We then install new rods bolts and then torque to recommended spec. We then remove material by the use of the Sunnen 1810 hone for small removal amounts of less than ten thousands.This machine uses an abrasive stone to remove metal and we can finish the rod to better than factory spec maintaining one tenth of a thousandth since we are doing each rod one by one rather than by mass production.
