Hello, It is well known that the camshaft adjusters often give up the mind. After my research it is because of the pen that slips out of the pulley hole and digs in there and that gets worse and worse. Some time when the box then rattles for seconds after starting. Since the evil is only the plate it should be easy to rebuild. The pen can be turned first. The pictures are not of me, but show what it is about. Now my question: Does this already have Is there any manufacturing drawings? Would be great if someone could help. Greetings Markus
