Ah, sorry - ya threw me with the image of the tensioner arms (not yours) - I thought those bushed arms are from the AC tensioner... RealOEM only shows a bush on the AC tensioner shaft.
But there
is a bush on the main belt tensioner shaft (obviously),
but it seems it is only sold as part of the main timing cover...
It may be that the bush used on the main belt tensioner is the same as the AC bush - the Russion forums (where you found the above image?) seem to infer they are the same.

But I guess your problem is.... you cannot remove the bush without pulling the tensioner arm out the front first. And that is what is stuck, right?
With any luck, when you pull the arm out (not sure how to do this - limited lever force might work) the bush wil come with it. If not, you are going to need to remove the alternator (and EGR pipe?), remove the tensioner mech (#2, after removing bolts #1) from behind the timing cover, then drive the bush (and arm if still stuck) out from behind the cover.
From a Russian forum...
Quite the pickle, if the video on this M57 E39 is anything to go by!

How do these arms ("poker" as the Russian forums translation calls them!) and bushes get so worn!!? They should not move about that much, unless the belt tension is all over the map!
Good luck!!
