Broken Odometer

[Sigurd Jarlson]

So the odometer in my 1989 Regal coupe is nonfunctional. I knew this when I bought the car. Not a huge deal, but it would be nice to have a working one.
 pulled the instrument cluster out of the dash and I didn't see any obvious issues like a broken wire or stripped out gears from the little motor to the numbers. I wasn't sure how to test if the little electric motor was functional aside from making sure that it spins freely, which it does, as do the numbers on the odometer "wheel". From other posts on here I see that this is a common issue, but I didn't see any posts that actually addressed how to repair it. Does one replace the motor? I googled the numbers on it but nothing that looked similar came up. Is there a part number? Is that the most common fix?

Thanks
