Notes:
We stock a wide variety of speedometer gears for Motometer, VDO, and other speedometers and instruments. Unfortunately, it is not possible to determine the exact combination (vehicle model to gear variant) for every model. However, we have separate offers in our shop for the most common combinations.
Buying a used speedometer might save you the cost of repair, but it carries the risk that the gear will break soon.
Storage periods and cold temperatures are particularly damaging to the gears. Furthermore, repairing your speedometer will preserve your original mileage reading!
If you have already disassembled the speedometer, it is also advisable to replace the bulbs. These lose a noticeable amount of brightness over the years. They are available at any car dealership and auto parts store.
Your advantages:
Our gears are injection-molded from high-quality thermoplastic: This allows for very good dimensional accuracy and an involute tooth shape that runs particularly smoothly against the mating gear.
If you disassemble the speedometer beforehand, please note that the speedometer needle shaft is very delicate. Grip the speedometer needle in the middle and turn it counterclockwise. Pull gently while doing so. Friction is all that holds the needle on the shaft.
