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

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

Excellent processing quality

Description:
If the odometer/daily odometer 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.

Dimensions:
Total diameter = 17.60mm (20 teeth)
Diameter of smaller gear = 12.05 mm (29 teeth)
Measured from tooth tip to tooth tip

Variants:
We can say with great certainty, but not with 100% certainty, which model has which gear size installed. Too many influencing factors (engine type/transmission type/year/model) play a role here.
However, the following data will reliably help you determine the correct gear:
Variants of this dual 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 mating gear: 47 teeth
20x29 (17.60mm/12.05mm) Number of teeth of the opposite mating gear: 41 teeth
20x30 (17.60mm/12.55mm) Number of teeth of the opposite mating gear: 40 teeth
20x32 (17.60mm/13.40mm) Number of teeth of the opposite mating gear: 38 teeth
If in doubt, simply count the teeth of the gearwheel in which the smaller gearwheel engages.

Advantages:
Buying a second-hand speedometer may initially save on repairs, but there is a risk that the cogwheel will break in the near future. In particular, storage times and cold temperatures cause additional damage to the gears. Due to an incorrect choice of material by VDO, all original gears of this type will break over time!
If you have disassembled the speedometer, we also recommend replacing the bulbs. These lose their performance noticeably over the years.

Quality:
Our gearwheels are elaborately and faithfully manufactured using the injection molding process and are not 3D-printed in-house components. 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, 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.

If you disassemble the speedometer in advance, please note that the shaft of the speedometer needle is very sensitive. Grip the speedometer needle in the center and turn it counterclockwise. Pull gently. Friction is all that keeps the needle on the shaft.
