Didn't end up being too bad. Took maybe an hour to get the intake manifold out, could do it faster a second time. Once that was out removing the alternator was easy.
Took a few photos, this one shows the gear-like toothed wheel that drives the alternator via a rubber coupler (alternator has already been removed). The bolt in the center had backed out so it just spun freely. There's no lock washer or thread locker used on that bolt for some reason, I think I will use Locktite when I reinstall it. https://drive.google.com/file/d/1kiPAceYigBC9HKw_rFi2tDFg7xShR6Wj/view?usp=sharing Here's the back side of that toothed drive wheel, some cracks and a bit chewed up from wobbling loose so I'm going to replace that. https://drive.google.com/file/d/1hQFEgoI17JXNARdU8ooO_Tck-c7THZoj/view?usp=sharing The teeth on that wheel fit into the rubber coupler, which drives a similar toothed wheel on the alternator. That rubber coupler seems in good condition so thinking I'll keep it. New one is $80 (!). The alternator looks rather old but turns smoothly and replacing it with a Bosch reman would add about $340 to the repair cost. It's not a terrible job to get in there now that I've done it once, so I might just keep it and see how much more life I get out of it. Or maybe take it to AutoZone and have them test it. https://drive.google.com/file/d/1fZVDFkVCrg25YX5ijdMniZt53vWnek0N/view?usp=sharing On Sun, Feb 4, 2024, at 16:02, Craig via Mercedes wrote: > On Sun, 04 Feb 2024 15:28:08 -0500 Allan Streib via Mercedes > <mercedes@okiebenz.com> wrote: > >> To get at the alternator and coupling, the intake manifold has to come >> off. > > You're kidding! > > >> So I'm going to look into that job.
