W124 Vibration Problem

Hi, I'm a UK member whos the proud possessor of a 1990 w124 250D I have a vibration problem at around 1000rpm static and mobile. Engine mounts are new, I suspect the bottom pulley is at fault as when I watch the serpentine belt as the vibe occurs it seems to flicker coming off the pulley.
Have any members experienced this problem and can you advise as to any pitfalls I may come accross in trying to sort it out.

How does your belt tensioner look?

Sorry for the delay in response

The tensioner was changed about a year ago after a truly amazing howl came from it (the bearing had collapsed. I have just changed the steering pump in search of this problem (once removed one of the mounting brackets was found to be completely sheared from the pump body).I intend to remove the bottom pulley and recheck the torque setting, Ive had that particular problem on LandRovers in the past while in the military.

Just as a point gentlemen/ladies I have been using this site for problem solutions for a couple of years now, the vacuum gear change in-sites have been particularly useful but I have been reluctant to join in.
I have worked with my US cousins on many occasions and have found them to be generous in their ability to share information. I look forward to being a more active member of the site.
If you are stuck for parts may I recommend the Mercman in the UK in my home town of Southampton (he does ship) he has a Merc only breakers with a stock you wouldn't believe
