If the odometer/daily odometer has failed on your vehicle, this gear is almost always the cause. The original beige/brown gears crumble after the years due to a material defect and need to be replaced.

Dimensions:
Total diameter = 17,60mm (20 teeth)
Diameter smaller gear = 12.55mm (30 teeth)
Measured from tooth tip to tooth tip.

Variants:
Most 911 G models (and some 944s) have this 20x30 installed! However, the 944 may also have the 20x21 or 20x22 installed. You can find these in the store by searching for example "20x21".
We can say with great certainty, but not 100% certainty, which model has which gear size installed. Too many influencing factors (engine type/transmission type/transmission/differential type/year/model) play into this.
However, the following data will reliably help determine the correct gear:
20x21 (17.60mm/9.00mm) number of teeth opposite mating gear: 49 teeth 911/928 mph/944
20x22 (17.60mm/9.40mm) number of teeth opposite mating gear: 48 teeth 911/944 mph
20x23 (17.60mm/9.65mm) number of teeth opposite mating gear: 47 teeth 944(S2)/911(G)
20x29 (17,60mm/12,05mm) number of teeth opposite partner gear: 41 teeth some 928 km/h
20x30 (17,60mm/12,55mm) number of teeth opposite partner gear: 40 teeth 911/944
20x32 (17.60mm/13.40mm) number of teeth opposite partner gear: 38 teeth 928 km/h

Just count the teeth of the gear this gear meshes with and/or use the dimensions to help you.

Advantages:
Buying a used speedometer initially saves the repair, but also carries the risk that the gear breaks in a timely manner. In particular, storage times and cold temperatures additionally damage the gears. Due to an incorrect choice of material by VDO, all original gears of this type will break over time!
If you ever disassemble the speedometer, it is also recommended to replace the bulbs. These lose noticeable power over the years.

Quality:
Our gears are intricately injection molded true to the original and are not 3D printed proprietary parts. We work with a manufacturer that specializes in the production of plastic gears and is the global market leader with its repair solutions.
The so-called involute tooth geometry is maintained, which is the only way to ensure low-friction sliding of the tooth flanks between the gear pairs.
The material we use is the thermoplastic Celron with graphite additives. These ensure low friction and wear-free operation.

Scope of delivery:
1 gear

Suitable for:
Porsche 911 (75-89) (older models = mechanical speedometers have the M17 installed).
Porsche 944-II (05.85 and up) (older models = mechanical tachos have the M11/M15/M17 installed)
Most 911 G models (and some 944) have this 20x30 installed !
However, the 944 may also have the 20x21 installed.
However, the 911 can also have the 20x22 installed. You can find this in the store via the search e.g. "20x21".
Although we can with great certainty
but not to 100% certainty say
which model has which gear size installed. Here, too many influencing factors (engine type / transmission type / transmission / differential type / year / model) play a role. If, contrary to expectation, you need a different gear
