I'm wondering if anyone here has the part numbers for each of the SC and Accessory belt idler pulleys. The two I'm interested in are those that are on the belt tensioners. They appear to be sold by MB as part of the tensioner assemblies.....which I don't need. These are actually for my '03 SL55, but I've not had luck finding anything on that Forum.

I'd be equally interested in simply replacing the bearings themselves if anyone has info or advice on that avenue.

Thanks, MK19

We have billet replacements


for about half the MB price and better bearings.
