I've got to replace the threaded rod, belt tensioner adjuster on my 1993 300SE. Does anyone know what this requires? What has to come off to get to the rod? Also does anyone know how to remove the Pulleys without an impact wrench? I tried to get the power steering pulley off in order make some room but I just kept spinning it.

Anyone know where to find the Rod? I looked in the parts bin but only found the tensioner pulley w/o the rod.
