My 92 400E has belt squeal, and I adjusted the tensioner (after loosening the center bolt!) and put the (new, was missing!) pointer between the center two lines, but it still squeals.
Pullling the tensioner, the adjuster plate flats have worn into the tensioner shaft flats, so I tried flipping the adjuster plate over and swapping its location onto an unworn position on the shaft flats. Still squeals.
This is a terrible design. The manual shows two later configuration tensioners, one of which the catalog shows applicable to later engines than mine, but it includes a note that if installed on earlier engines, you need two additional little pieces. This implies a retrofit is possible.
Has anyone retrofitted the later config tensioner? It looks totally different. How does it mount? Are other hardware needed to mount it? Do you just swap the pulley itself over?
Any comments/help would be greatly appreciated! (Please cc me directly with any responses, as I may not have access here from work!)
