[Broken Odo]

Hi, new to the board. I have an 82 240D - Automatic, with about 64K miles. The speedo works fine, but the odometer and the trip odometer do not function. Can anyone tell me how it connects to the dash? Is it run off a seperate cable from the speedo, run off a gear from the trany? Any help here would be MUCH appreciated!
Thanks in advance[B)]

Odometer

This is extremely common on Mercedes. The odometers will often brake when they are reset while the car is moving. Otherwise they simply wearout after 200,000 miles.
The cluster is run off of a cable in the rear of the cluster. The plastic gear is brittle with age. This can often be fixed with super-glue. You can purchase replacment kit for ~$50 - $75.
