603 - tensioner re-install... I hope I didn't screw this up

[MercFan]

I was in the process of re-installing the new tensioner lever into my 300SDL. The big hex bolt that connects the tensioner to the block... I have used the big 1/2 drive to tighten the big hex bolt - I wanted it snug but it felt like it gave in at little at the end... I removed it and inspected the threads... don't seen anything bad but I'm afraid to tighten it again. I HOPE and PRAY I didn't strip those threads!

Can somebody plz provide a quick spec for tightening torque for this big bolt?! Again, it's the tensioner that has the idler pulley and shock absorber installed to each end of it.

Quick help will be appreciated.
