Question about 1995 Porsche 968
You can get the manual and trace the cable to the transmission.

STEP 1: speedometer Removal.
Using a cloth covered screwdriver, gently pry the speedometer out from your dashboard. The rubber ring around the edge comes out too, so get under that with the flat screwdriver and pry out. Do NOT use the neighboring gauge as a leverage point. The black trim ring is very easily scratched. Once you get it started you should be able to get your hands on it and pull it out. Unplug the connector and head to a clean work area.
STEP 2: Dis assemble Speedometer
TRIM RING: Remove the rubber grippy retainer ring. Remove the 4 screws from the back of the unit.
Now the soft metal trim ring needs removed by gently prying around the entire edge of the assembly to bend/lift the edge over the lip of the outside housing. This isn't pretty, but goes slow. Be careful not to scratch the ring beyond the lip. You won't see what you have done to it once the rubber retainer goes back on so don't worry about chewing it up a little bit. Keep slowly prying around the edge until it can be pulled out.
STEP 3: Trip meter reset button removal
There is a thick post over the thin post of the reset button. Support the button assembly below and pull the top off. This will take some pressure, but be sure to brace the assembly from below so you don't pull too ******* the lever where it clips to the drive gears.
Note: where the shaft gets thinner, that's where it separates.
STEP 4: Speedometer needle removal
This is the trickiest part of the job. The needle is pressed onto a shaft that is extremely thin. It feels like a pretty tough metal, but you HAVE to be careful here. Do not pull straight up. Do not put any torque on the shaft. Rotate the speedometer needle clockwise until it hits a stop point. Gently continue to rotate the needle while lifting up gently at the same time. The friction is all that is holding the needle to the shaft. Keep turning and prying until the needle comes off. Do not force it. I don't know that that shaft assembly is user replaceable.
Note: See how small the shaft is:
STEP 5: Dis assembly
You've come this far, there is nothing stopping you now. Take the two screws out of the faceplate.
Remove the motor -
STEP 6: The guts
Once the motor comes out, you Speedometer repair - dd1a149.jpg the drive gear and pod. Inside the pod is going to be your broken gear. Replace it with your new gear.
STEP 7: Reassembly of speedometer
This is completely reverse of everything else. Nothing is too tricky. Continue to take your time paying particular attention to the needle shaft. When reinstalling the speedometer needle, make sure you rotate while gently pushing down. Never simply compress the needle onto the shaft. Once it is in firm enough, use the stop points at max speed and 0 mph/kph to realign the needle with 0. Once everything is back together, also gently recompress the trim ring around the back of the speedo housing. You could use a black permanent marker to cover any scratches. Plug the unit back into the dash and reinsert into your gauge opening. Hopefully all is now re-recording miles.
Again, this is a VERY easy job. Not easy like a tire change - but only because you are dealing with a delicate instrument. If you have big, clumsy hands, you might want to forgo this exercise and send it to a pro. If you can be gentle with this, you should be OK.
