It’s an Allen drive wrench for 3/8 ratchet. Might be 1/2 inch now that I think 
about it.

Re: [MBZ] E300D/2.5 Turbo Belt Tensioner

[OK Don via Mercedes]

When I replaced the belt tensioner on that engine shortly after I bought
the car, I used brake cleaner to remove the oil, then blue Locktite on the
bolt. Apparently it didn't hold so well - - - probably needed better/more
cleaning.

I bought a 3 pc set at Autozone for $10 about 15 years ago. 
The big one is 17mm, I think the middle one is 14mm, so the small one might be 
12 or 13.

Socket? Or socket-drive allen wrench?

The latter is what is needed in this case.

That's what 13-3200hw.pdf says to do.

The spec is 100 Nm (73.8 ft-lbf). Yes, stripping out the hole would be
bad ...

[Kaleb C. Striplin via Mercedes]

Autozone sells a nice socket set that has that 12mm socket. I have never heard 
of putting sealant on the treads, I never have done it but I suppose it makes 
sense. You can probably use whatever thread sealant is available. I’m sure 
there is a spec for how tight to tighten the bolt, you want it tight but don’t 
overtighten it because you don’t want to strip out the hole.

There is oil everywhere.

I'm guessing it will cause problems with the Threadlocker Blue.

[MBZ] E300D/2.5 Turbo Belt Tensioner

[Craig via Mercedes]

I looked at the sections of the manual I posted a few days ago:

13-1202hw.pdf
13-3200hw.pdf
13-343.pdf

and everything looked quite confusing.

Searching on the Web, though, I found:

http://www.peachparts.com/shopforum/diesel-discussion/312419-diy-1987-300d-serpentine-belt-tensioner-replacement.html

with that, it didn't seem so confusing, so I took a closer look at the
belt tensioner on the front of the OM602 in our '90 E300D/2.5 Turbo and
found it was quite loose.

I went down to the local heavy truck repair shop (appropriately called
The Shop) which has done work on my trucks (and whose employees I have
befriended) and asked to borrow a socket-drive 12 mm allen wrench. They
had one and let me bring it home to use it.

I removed the bolt holding the idler pulley using my own 6 mm
socket-drive allen wrench and a 1/2" breaker bar. Yes, it was
appropriately tight so I did need the breaker bar.

I then removed removed the bolt and nut holding the top end of the spring
with a 13 mm socket.

I then put the 12 mm socket-drive Allen wrench on the breaker bar and
proceeded to loosen the bolt holding the tensioning lever to the front
cover. But it took hardly any torque to turn it! It turns out the bolt
was loose!

I have taken it out and found an oily mess, probably because the threaded
hole is open to the inside of the engine.

13-3200hw.pdf says to apply Omnifit 100 M orange sealant to the threads
to seal the threads and lock the bolt in place, but I don't have any of
that.

I'll have to clean up the threads in the front cover the best I can
somehow (anyone have any ideas?) and then use the Permatex Medium
Strength Threadlocker Blue I have.

I did notice that the two "end covers" to keep the dirt out of the allen
recesses of the bolts were missing.
