New connecting rod
A new connecting rod has been introduced on B6294S engines.
The mating surface between the cap and the connecting rod is not machined. It is aligned through a dedicated fracture surface.
Caution! If the cap is turned the wrong way and tightened, the structure of the fracture surface will be damaged and the connecting rod must
then be discarded.
Note! Blow the fracture surface clean with compressed air before reinstalling the cap.
