I'm tackling the heater core replacement in another thread here. Pulled the instrument cluster, and found that the reason my odometer has stopped working is because the shaft that has the gear driving it off of the speedometer has physically moved the plastic gear away from the teeth it meshes on. I pushed the shaft gently back into place, and spun the speedometer for a moment. Odometer and trip meter are working again.

So, what holds the shaft in place? A 'C' clip, maybe? I'm not seeing it.

The plastic gear is not slipping on the shaft. And, there's nothing laying there that could be the culprit, that I see.

Any ideas?
