Hi Rich,
I got the same this spring. You should take out the speedo. And take of the back. Inside you wil see a disk. Wich is magnetic and behind it a small gear. Mines was white. This one is probably broken. So the speedo works but the tacho not. Find a shop who repairs them and try to buy a gear. And replace it. And all will be fine. See this link http://obswww.unige.ch/~wildif/cars/...edo_repair.pdf This exlains a lot and how to do it. If you are not comfortabele to do it yourself let a shop do it. I hope this helps you.
Regards,
Alex

do you mean the trip recorder, being pedantic but a tachometer reads engine revolutions. if it's the trip, then yes its possibly the gear or drive, try giving the reset a few pushes, that may get it to work before taking things apart

Or to be punctilious, odometer.
Do the numbers line up? Unscrupulous people used to 'clock' cars, reducing the recorded mileage to increase their value by forcing the numbers round, sometimes damaging the mechanism.
