odometer not working
 

I have a '86 300SDL, 202,000 miles, speedometer is working fine, but odometer and trip odometer are not operational. What exactly do i need?

There was an article in the Star magazine several years ago that detailed very well the repair of the VDO odometer. It involves filing the flats off the shafts, sliding them out, cleaning lubricating and then sliding the shafts back in and crimping the ends.

The alternative if you don't need the trip odometer, is to remove the plastic spur gear that connects the two. This removes half of the friction load and allows the main odometer to work again.

Good luck,

odometer

How long has the odo and trip odo been non-op? Did you by chance reset the trip odo while the car was moving? Sometimes this causes a jam which stops the works, sometimes the jam can be cleared by multiple attemps at resetting the trip odo. May not always work, but an inexpensive try.
