when i purchased my '87 300D, the dash had been pulled out (assuming to fix the odo, it worked when i purchased it) but the dash wasn't all the way in..

so i pushed it in, knowing i have the MB dash repair kit in the trunk..

and now i have time to fix it again, trip odo sticks at xxx.x9 every 20 or so miles ( but works fine 40 degrees or below?!)

how in the world do you get it out?

and anyone else experience a randomly working odo?

The IP? Two hooks on either side, Mercedes dash removal tools.

Common problem, and why you can never really trust the mileage on 124's. When mine did this I JB Welded a metal flange across the two ridges on either side of the little gear. This keeps pressure on the gear to keep the pin in the hole. Works fine.

Disconnect the battery before you pull the binnacle. I shorted something out on the circuit board that made the oil pressure gauge dead and the tach goofy. I had to locate another board and swap them out. PITA.

As a couple of us mentioned above, it's not the 124, it's also 126, 123, Porsche, VW, Audi, Volvo, ... anything with a mechanical odometer that says VDO on it.

Good point. For whatever reason, I've only had this problem on my 124 so I guess I'm lucky...for now!

Here's a pic of my fix, sorry it's out of focus:

I'm new to "quoting." This is in reference to the post two up from here....

That's a good looking work-around. I, too, repaired my non-working Odo on my '87 300TD. Having read this thread prior to the repair, and seeing Jeff's post that simply re-inserting the shaft would only be a temporary fix, I figured if there were a way to physically keep the shaft from backing out the "repair" might last longer. I mounted a solid wire to the two screws behind the speedometer face plate (opposite the side on which you mounted your bracket). You can just make out the head of the screws in your photo. I bent the wire ends into a hook so so they would wrap around the screws and hammered them flat, so they're more like a washer, if you will. Then I just bent the stubby "U-shaped" wire around so it was not quite touching the shaft and put a dab of white lube on it, just in case the shaft did back out. The screws mount up tight and there are no clearance problems. I have no idea if this will work and only about 1000 miles on it, so I'm not claiming any success. But it was quick and easy.

Well damn, my odo quit again this week. Forget my "solution." I picked up an instrument binnacle for the circuit board and it's time to start cannibalizing more parts!

I have the tools, but it won't budge!
