Car is a 1989 (new shape) Volvo 740GL sedan.
The trip meter and odometer suddenly stopped working a few days ago and the speedometer drops to zero occasionally. A whack on the dash sometimes restores operation of the speedo but not the tripmeter or odometer.

I pulled apart the speedo unit and found this:

One of the teeth appears to be missing off the bottom right of the small grey gear. Is that normal? The large gear wheel is fine ( it was replaced a couple of years ago ).

Also found these dodgy-looking pins on the instrument cluster(second from the right):

There is also a dodgy looking one like this on the speedo unit too.
If they are bad how can they be repaired?

Thanks for any advice.
