Can the E38 Oil Pump Chain be tightened?

[Bimmer Nut Ed]

I remember last time when I checked the oil pump bolts on my e38, I mentioned here on the board that the bolts were loose, someone had said that I should have also tightened the tension on the oil pump chain. Mine seemed to have a lot of play.

Well, I have the pan off now, and I'm trying to tighten the chain and can not seem to figure out how to do it. I even checked out http://www.e38.org/

I'm talking about a 1997 740i btw.

Hmm, am I missing the obvious?

Kisses to you Bill R. Thanks again as usual. I just did not notice that it really is a "big" hex fitting in there. 8MM, inside that passenger side bolt hole (after you remove the bolt). I had removed the bolt and still could not see it. The validation in the ETK image made me persist. Thanks Bill. Yeah, I know, the ETK is the first thing I should pull out, and here I did it again, it was last. Part of my problem is, my cousin installed it on my PC in German, and it's a real pain to weed through the German to find the location to change it to english. It always defaults to German when I bring it up! Thanks all.
