2) Is it OK to reuse the compression spring ( 7i )?
3) Pressure valve carrier ( 7g ) can move around inside the hole. Shall I center it? What is the exact position for this?
4) Where shall I put the copper washer? EXACTLY on top of 7g?
Thanks for your info.

1) Good.
2) Yes.
3) It can move around, but when you re-install the holder, it must be centered to allow the holder to screw in place.
4) It just lays on top of 7g. Use a small screwdriver to get 7g and 7f mostly centered before re-installing the main holder (7).
Don't forget to use the 3-stage torque procedure, which is not mentioned in the 602/603 FSM, it's only described in the TDM (Technical Data Manual) and 605/606 FSM. Tighten to 30Nm, release, 30Nm again, release, and then tighten a third time to a final torque of 35Nm.
See the "Installation Note" on page 2 of this PDF file:
