Tightening the cap for the connecting rod
Install the end cap. Check that markings correspond. On late
types of connecting rods the mating surface between the cap
and the connecting rod are not machined. It is aligned through
a dedicated fracture surface.
Earlier types have serrated surfaces that only align one way.
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 surfaces of the connecting rod and end
cap dean using compressed air before installing the cap.
