Didn't you say that you just put this one back into service after a
long downtime? Are you sure that the tensioner is backing off or is it
the rust on the pulleys wearing the belts down and causing the
loosening?
It's coming loose, definitely. Belts aren't wearing.
Uh, the clamp bolt.
Jim,
There are 3 bolts that have to be loosened.
2 on the alt one top one bottom and one where the bracket mounts to the
block.
If you don't loosen them the adjusting bolt will bend DAMHIK. when you
get the Alt
adjusted tighten them back up. They are either 15 or 17 mm.

Now I see what's going on! The 17mm nut on the top alternator
bolt is missing altogether. I put in one from the junk box
(w/lock washer) and tightened it. That oughta help, and it
certainly explains the suddenness of the problem.

The 17mm nut on the top alternator bolt is missing altogether.
I checked my records, and find that there was a spate of
spontaneous belt loosening three years ago, no mention of
boltery. From this, and the state of the exposed end of
the bolt, I suspect that the nut has been missing a _long_

Tighten the mount bolts...
On both my 240Ds to tighten the bolt I first have to loosen the (17mm I
believe) mount bolt, then tighten the adjuster bolt, the re-tighten the mount
bolt.
Same story here.
Only one add point - check the entire bracket, as it was cracked in my
car
There should be a large square-nut/follower that rides on the long
threaded bolt. That is a split nut, and the nut should have a bolt
from the top eye of the alt through 1/2 of the split nut threaded
into the far side if the split nut. IF the split nut is flipped
over, the small bolt from
My wife started off on a road-trip halfway across the state Friday, in
the Chicken Wagon ('83 300D) and called because the car was shrieking
at her. Very displeased she headed back home whereupon I tightened
the alternator belt, which had (somehow) gotten just about as loose as
it could be.
Usually, the rust keeps it locked solid.
Maybe try purple loctite?

My '83 300D has the alternator attached to a bracket which has three bolts;
two holding the alternator and one pivoting the bracket IIRC. If all bolts
aren't tight the belt can get loose, but mine has never gotten as loose as
yours seem to be. I would wonder if the bracket might be broken or
