Internal Odometer Speedometer Gear - Multiple Tooth Count Options
Restore the operation of your classic Porsche speedometer with this OE Match Internal Odometer Speedometer Gear. Manufactured to replace the original internal plastic drive gear, this component restores the mechanical drive to the odometer and trip meter when the original gear has become worn, brittle or broken.
The internal odometer gear is housed within the speedometer and transfers drive from the speedometer mechanism to the odometer assembly. Over time, the original plastic gear naturally deteriorates through age and repeated use, often causing the odometer and trip meter to stop recording mileage while the speedometer needle continues to function normally.
Replacing the failed gear is a cost-effective repair that allows you to retain the original speedometer while restoring accurate mileage recording.
Choosing the Correct Gear
There are multiple tooth count options fitted to speedometers. Before ordering, the speedometer must be opened so the original gear can be inspected and the correct tooth count confirmed.
The replacement gear consists of:
- Outer
gear: Always 20 teeth
- Inner gear: Available with 21 to 32 teeth, depending on your speedometer.
If the original gear is too damaged to count accurately, count the teeth on the mating gear instead. Use the following guide to determine the correct replacement:
Teeth on Mating Gear - Required Gear
49 teeth 20 x 21
48 teeth 20 x 22
47 teeth 20 x 23
41 teeth 20 x 29
40 teeth 20 x 30
38 teeth 20 x 32
Please Note:
The speedometer must be dismantled to confirm both the correct gear
style and tooth count before ordering. Ordering without verifying the existing
gear may result in purchasing the incorrect replacement.
Key Features
- Restores odometer and trip meter operation
- Direct replacement for worn or broken internal plastic gears
- Multiple inner tooth count options available
- Outer gear always features 20 teeth
- Cost-effective alternative to replacing the complete speedometer
- Ideal for instrument restoration and repair
The original instruments fitted to early Porsche models are built to last, but one of the few components that commonly fails is the small internal plastic odometer drive gear. Heat, age and decades of continuous operation eventually make the original material brittle, causing the gear teeth to crack or strip.
Fortunately, replacing the damaged gear restores normal operation while allowing you to retain your original factory instrument.
Common Symptoms of a Failed Odometer Gear
- Speedometer needle operates normally
- Odometer has stopped recording mileage
- Trip meter no longer advances
- Intermittent odometer operation
- Broken or cracked plastic gear inside the speedometer
Because Porsche used several different gear ratios throughout production, identifying the correct gear before ordering is essential for a successful repair.

There are potentially two gears that can go bad. First is the gear on the side of the speedometer. If your gear is metal then you will not need this gear. If it is plastic inspect closely where the shaft comes through the gear as there will generally be a hairline crack and the gear must fit tight.
