The odometer in my '86 740 hasn't been working for a few months. A recent post said I could be as lucky as just needed to unstick a gear. However, I did not find a stuck gear. http://www.odometergears.com/ says that a common failure is a gear in the electronically driven volvo speedometer. My car's speedometer is not cable driven.

My question is how do I get access to that little gear to see if it's broken? I've got the speedometer/odometer part out of the rest of the cluster. I found little tabs to remove the device that controls the speedometer needle, but I can't remove it because the needle is connected to it and I'm afraid of using too much force to disconnect the needle.

Thanks,
Nathan
