@ Helmuth: yap - I guess force can do more harm than benefit in this case.
@ emil: - would you recall the parts that needed to be replaced? I would say that they should be listed here:

But which one(s) ?
It does not seems to be a rocket science to replace any of those, I just do not feel like leaving the door dismantled until the parts arrive and doing it twice is also not my hobby

Thx,
