Instrument cluster gear for ROLLS ROYCE Silver Seraph Corniche VDO 20x29

Instrument cluster gear for ROLLS ROYCE Silver Seraph Corniche VDO 20x29

Excellent workmanship

Description:
If the odometer/trip meter on your vehicle has failed, then this gear is usually the cause. The original beige-brown gears crumble over the years and need to be replaced.

Variants:
We can say with great certainty, but not with 100% certainty, which model has which gear size. Too many influencing factors come into play here (engine type/gearbox type/year of manufacture/model).
However, the following data will reliably help you determine the correct gear:
Variants of this double gear for VDO speedometers:
20x21 (17.60mm/9.00mm) Number of teeth of the opposite partner gear: 49 teeth
20x22 (17.60mm/9.40mm) Number of teeth of the opposite partner gear: 48 teeth
20x23 (17.60mm/9.65mm) Number of teeth of the opposite partner gear: 47 teeth
20x29 (17.60mm/12.05mm) Number of teeth of the opposite partner gear: 41 teeth
20x30 (17.60mm/12.55mm) Number of teeth of the opposite partner gear: 40 teeth
20x32 (17.60mm/13.40mm) Number of teeth on the opposite partner gear: 38 teeth
If in doubt, simply count the teeth on the gear that the smaller gear meshes with.

We will send you illustrated repair instructions (German/English) via email for the repair.

Advantages:
While buying a used speedometer saves you the initial repair cost, it carries the risk that the gear will break quickly. Storage times and cold temperatures in particular cause additional damage to the gears. Due to VDO's incorrect choice of material, all original gears of this type will break over time!
If you have disassembled the speedometer, we also recommend replacing the light bulbs. These lose noticeable performance over time.

Quality:
Our gears are elaborately and faithfully manufactured using an injection molding process and are not 3D-printed in-house. 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 retained; this is the only way to ensure low-friction sliding of the tooth flanks between the gear pairs.
We use the thermoplastic Celron with graphite additives. These ensure low friction and wear-free operation.

If you disassemble the speedometer beforehand, please note that the speedometer needle shaft is very sensitive. Grip the speedometer needle in the middle and turn it counterclockwise, pulling gently. Friction is all that keeps the needle on the shaft.
