Use of parts other than those directly specified by the manufacturer mean the equipment becomes re-furbished and requires full CE re-certification!
Only if you "bring it to market". CE marking is not a safety mark it is a commercial thing, the idea of it was to ensure that goods made in the whole of the EU were made to the same standard and that countries where labour was cheaper (usually in southern Europe) did not under cut those made in areas where labour is more expensive.
So if you totally rebuild something with lots of different parts but continue to use it in your own organisation you do not need to CE mark it. i.e. you do not have to use OEM parts.

PS If you are going to blindly follow the manufacturers instructions to the letter why are you in a job? Surely you just put everything out to contract? It is much easier to manage outsourced contracts than staff and the costs associated with them such as training holidays and sick leave.
