Checking Markings
Install the two old screws for the flywheel and carrier plate at the rear edge of the crankshaft.
Turn the crankshaft so the piston in cylinder 1 is at bottom dead center (BDC).
Check that there are markings on the cap and connecting rods. Check which way the markings are positioned (exhaust and intake side). Make a note of this.
If necessary mark with a center punch or a number punch. See Marking the connecting rod (where applicable) .
Scheme 478
A new connecting rod has been introduced on certain 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 using compressed air before installing the cap.
