Gear wheel instrument cluster for Porsche 911 944Mph odometer repair 20x22

Description:
If the odometer on your vehicle has failed, then this gear is almost always the cause. The original beige-brown gears crumble over the years due to a material defect and have to be replaced.

Dimensions:
Total diameter = 17.60mm (20 teeth)
Diameter of smaller gear = 9.40 mm (22 teeth)
Measured from tooth tip to tooth tip

Variants:
The 20x29 is also occasionally fitted in the 928. Simply search for "20x29" in the store. Models with mileage tachometer always have the 20x21 installed!
We can say with great certainty, but not with 100% certainty, which model has which gear wheel size installed. Too many influencing factors (engine type/transmission type/transmission/differential type/year/model) play a role here.
However, the following data will reliably help you determine the correct gear:
20x21 (17.60mm/9.00mm) Number of teeth opposite partner 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 (S/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

Simply count the teeth of the gear into which this gear meshes and/or use the dimensions as a guide.

Hint:
Occasionally, other sizes are also installed. We therefore recommend counting the teeth and informing us of the number when purchasing.
