I was just going back through the pile of receipts that came with wagon that I purchased last June and noticed these two recommendations from MB of Boston that the previous owner did not address. The car has an additional 4k miles that have been put on it in that year.





I assume the "supercharger tensioner pulley" is this:

Is the double pulley this one?:

I read the DIY about swapping our the bearing, but I can't quite seem to figure which bearing to order for it. I have seen a few different option in there and other places, but nothing concrete.

11 = tightener pulley, part #1132020419
29 = belt tightener, 1132000170
8 = tightener pulley, 1132020019
23 = belt tightener, 1122000970
V-belt, 1139970292









I just want to make sure I am ordering the right components based on their wording.


thanks

ASP. I just replaced my double idler with their two pulleys. Cheap and decent quality.
