If your speedometer works, but your odometer (mileage counter) is broken then you can almost guarantee it because your old primary gear has failed inside. These were lubricated with grease when the guages were built by VDO, and the grease eats through the gear over time, turning it into mush.
This is a new gear AND pod set for Porsche 964 and 993 MPH, as you need to change both at the same time
You need to open your odometer and check that you have the following fitted BEFORE Purchase. There ARE variations, but this is the most common for MPH Cars. You check by counting the teeth and measuring the gears
- 15 tooth small gear (approx 6.8mm)
- 17 tooth POD (gear one side, spindle the other, approx 15.4mm). The original pod is normally red.
We do have some of the other variations (like the blue/green 16 tooth etc) in stock, just check our other ebay items/eBay shop to purchase those instead....!
Changing the gear is quite easy, and the best bit is its not only significantly cheaper than a replacement speedometer/odometer, but you also get to keep the date stamp on the back (which is a quick check to see if a car is clocked when buying (the date on the back must be before the car was built)).
Repair TIP
To remove the gauge, first disconnect your battery, then carefully pull the gauge towards you (wiggle side to side). Its only held in by a rubber ring. Take a picture of the wiring for reference and/or masking tape numbering. Use some needle nose/pliers and wiggle (side to side) the little light bulb holders to remove them.
