AC compressor internal damage, should replace what other parts?

I read some where that if your HVAC compressor has internal damage you would need to replace the following items:

Compressor
intake and pressure lines with seal rings
expansion valve
receiver/drier

I don't have a problem replacing every thing that should be replaced I'm just not sure if this is normal procedure?

Also at what point in this repair should the other parts be flushed out?

Does this system have a orifice filter? Alldata didn't show one.

yes, that list is correct, except I did not replace the lines.
See this http://www.benzworld.org/forums/w210...ac-system.html there are 3 sections, thats the first one.

There is no orifice filter, its controlled by the expansion valve.

Outstanding gathering of information. I noticed there was no talk about flushing the system. I'm guessing this isn't normal practice?
