Odometer stopped working ?
still aint got me arse into gear with pics! will do some soon! if your speedo still works and your odometer dosnt you will find that a small plastic cog (size of half p piece) is broken .
1- disconnect speedo from housing , unscrew speedo cable from back , take note of which light/wires connected where
2 - the bezel is pressed onto the body.carefully 'peel' the bezel off with a watchmakers screwdriver , careful not too scratch bezel.
3- lift off bezel/glass , then unscrew 2 retaining screws on back of body , lift 'workings' from inside body.
4- thr a series of cogs/wormdrives (loads of em) the odometer is driven , however - fortunately for us the ones we need are the easiest ones to get to
5 - the small cog is driven by a worm drive - the tolerance is quite wide and the cog is alot softer than the worm drive. if the cog loses one tooth (quite common) it will lose drive , if the cog spins on the shaft , you lose all drive, bugger!
6 - here is a pic of what i mean , will find website in a mo!
Many thanks for the info ELVIS, though a little too late for me (I had the odometer professionally repaired for € 80 last week). But do I understand it rightly? Does that company charge £ 45 for a cog or do they decline to sell the cogs and charge £ 45 for reconditioning the odometer instead?
Mine's just started doing that. That would be far better than getting a new speedo! Where do I get the little cogs from?

It sound like I am too late for some but I have come across this place in the US that sells the gears for US$25 each. Hopefully it might help someone else. Odometer Gears - MB

Well done - just what we needed.
Who is the company that does recons? It still may be the cheapest option for me.

Just had a very similar problem and found the above very helpful. However, I've fixed it with a bit of a 'bodge' but it works OK (how long for is another matter - we'll see). The attractive part is that it was free.
In the pic, you will see a small white (slightly yellowing) gear wheel that is driven off a worm gear on the speedo input shaft. The shaft holding this wheel and the small red worm gear was a bit slack on its 'bearing' just inboard of the red worm. The bearing consists of a u-channel in the metal with the open side closed off by part of the white plastic body. The small gear had worn just enough that one of the teeth failed to mesh but, if the slack in the 'bearing' was taken up it meshed OK.
The solution is a small strip of plastic (clear plastic, just visible) inserted between the metal u and its plastic closure. That takes up just enough play for the gear to engage in the input drive worm again. The plastic is bent back through 180 deg over the metal base so that it is held in place by the speedo rear cover when it is replaced.
like this but with less teeth though , only one meshes at a time! only one company stock em ov er here but wont sell em singly but will charge you £45 for a recon - takes 15 mins to replace cog!!
