95 E320 M104 Tensioner

[HCH]

I have spent hours searching this forum and the net and no luck. This was part of another thread but I've broken it out here in a blatant attempt to attract more attention and hopefully an answer.

How do I adjust the tensioner so that I can remove and replace the serpentine belt?

I've read all the posts I could find and cannot for the life of me relate what I've read to what I see in my engine.

Re: other threads: I don't see any nuts that are pointing up, I see no keyed allen bolt on a pulley. None of the pulleys are 19 mm hex heads.

This is a very late 95 E320 (May 95) engine # 12 090072

Pulley Diagram mine is the lower right.

Atop the tensioning pulley is nothing much. A combination bracket basically. It DOES NOT look like this:

Tensioner

Another post mentions just tightening the tensioner pulley bolt until it moves in, but that's on a 96 104.

I think I'm missing something basic - it's been hours of staring at the engine and checking posts here. I'm not a total idiot (usually). The fan shroud is pulled so I do have a decent view.

I've attached photos of the front of the engine.

Any help with this tensioner setup would be grand.
