1984 OM617 with turbo.

I have all of the manifold bolts off and the exhaust manifold is about 1/2 in from the head. Of course, the intake manifold is very loose. But, the exhaust manifold won't budge any more than about a half inch. Are there any hidden bolts under the exhaust manifold? How does the accordion tube come off?

I did a search and didn't find anything on this.
