Volvo MD11C

Can anyone please tell me how to remove the injectors on this engine ?
I want to take them in for servicing but don't know how to remove them.
I removed the oval shaped plate held on by two nuts and tried gently tapping the injectors but no luck.
The Volvo manual is not helpful.
Any help much appreciated

The injectors sit within a copper tube which is swedged into the cylinder head at its lower tip. Over time, carbon accumulates between the injector tip and the bottom of the copper tube, and also dirt, rust and crime and corruption build up around the injector body and the tube. The object is to get the injector out of the tube without disturbing the copper tube in the cylinder head.

Probably the best course of action here is to soak the area where the injector enters the tube with penetrating oil for a day or two to try and loosen the rust. Then try to rotate the injector with a wrench to break it loose. If you have room, you could use a slide hammer to try to lift the injector, or a ladies foot to lever from underneath. Be careful when levering that you don't put too much pressure on the head.
