What happens if the odometer on a Porsche 928 fails?
This article applies to the Porsche 928 (1979-1995). Your odometer has one job–to keep track of the distance traveled. When it fails, it can cause some title issues as the mileage becomes exempt. Not only that, but it can also throw off your scheduled service intervals and inadvertently cause trouble to your engine.
Why does my odometer keep sticking on my Porsche 911?
With age, the odometer can stick, and if it does, then these plastic gears will grind and become destroyed. The other design flaw involves a pot-metal gear that is pressed onto the main odometer shaft. After many years, this gear often comes loose on the shaft, refusing to turn the odometer any more.
What to do if your odometer doesn’t spin?
If the odometer doesn’t spin freely, then your speedometer cable will turn the gear and chew it up again. Make sure that the odometer gears turn freely before installing your new worm gear. Place the odometer/speedometer mechanism back into the housing and mount it with the two screws you removed earlier.
How can I test my Porsche 911 speedometer?
It is possible to test the operation of a mechanical speedometer using a hand drill hooked up to the rear of the housing, but in most cases, it’s just easier to reinstall it back into the car. Replace the gauge face and reattach the outer ring by pressing down the ring around the outside of the gauge.

Where is the speedometer located on a Porsche 914?
This speedometer mechanism mates into the back of the odometer mechanism, as shown Figure 10. The main failure point within the odometer is the pot-metal gear that is pressed onto the odometer drive shaft. The shaft holds all of the number wheels together and is connected by a worm gear.
Why is my odometer not working on my 914?
The odometer didn’t work, and when advancing the trip counter, the mileage would advance by one mile. Having fixed this before on my 914, I quickly fixed the one in my 356. The basic problem with the odometers lies in the fact that a pot-metal gear that was originally press-fit onto the odometer drive shaft often comes loose.
How do you replace the odometer on a Porsche 911?
Replacement of the gear is straightforward: simply loosen up the assembly and swap out the gear. It is important to keep in mind the reasons why the plastic worm gears may have been chewed up. If the odometer doesn’t spin freely, then your speedometer cable will turn the gear and chew it up again.
