Canada Vehicle(s): 1989 280GE Posts: 1347  | Re: Odometer Repair, how to Hi Ryan, I didn't need to fix the odo on mine (speed drive was noisy) but the disassembly is the same....you need to work around the back edge of the black bezel ring that retains the glass...it's crimped on. Think of it like opening a can, but be nice with it you will have to recrimp it later. Then afterwards remove the 2 small bolts at the rear and the guts will come out. From this point on it's like watch repair. Here's some pics of when I did mine. To get at the odo, you will have to remove the needle and face plate...be warned the needle is set with some preload by the spring and you should check that before prying it off. I used a drill and an old speedo cable to spin check the calibration, you need a base setting for reassembly. Mine was 3000rpm on the drill made 85-90 km/h on the speedo. Now you can gently pry off the needle, I used a door panel tool tape to protect the faceplate. Next remove the 2 faceplate screws. Next remove screws that hold the assembly together. Now you will have to separate the odo assembly from the speedo drive assembly... tap the speedo drive needle out of the spring...(do this very gently if you bend it your screwed). Now the speedo drive can be removed and the odo drive gears accessed. Reassembly is the reverse...the tricky part is setting the preload on the needle so your speedo is calibrated...a small screw driver can be used to hold the spring while the needle is adjusted...then bench test...not easy but I did it this way. Once you have it all working place it back in the can and crimp the bezel. A speedo shop will charge over $200 for this complete job.
