Ok, then the plan would be to:
1) loosen up the belt so that camshaft and crankshaft can move independently
2) rotate the cam and/or crankshaft back and forth so that the camshaft pin hole advances from 10 to 16 o'clock to be locked
3) hopefully and when locking the camshaft, the crankshaft can be locked also since it has got into the correct position too
4) tighten the belt and remove both pins
5) rotate the engine at least 2 complete turns clockwise and verify that the 2 pins can be inserted into the 2 slots at cam and crankshaft after rotation

If so, are there any risks that the engine be more out of alignment than at start of procedure ?

Thanks for your help.
