20x29 Speedometer Gear for Ford Fairmont Fairlane Falcon XD XE XF XH '79-'88 Description: If the odometer/trip meter on your vehicle has failed, this gear is usually the cause. The original beige-brown gears crumble over the years and must be replaced. Variants: While we can say with a high degree of certainty, we cannot guarantee 100% which model uses which gear size. Too many factors (engine type/transmission type/year of manufacture/model) are involved. The following data reliably helps in determining the correct gear: Variants of this double gear for VDO speedometers: 20x21 (17.60mm/9.00mm) Number of teeth of the opposing partner gear: 49 teeth 20x22 (17.60mm/9.40mm) Number of teeth of the opposing partner gear: 48 teeth 20x23 (17.60mm/9.65mm) Number of teeth of the opposing partner gear: 47 teeth 20x29 (17.60mm/12.05mm) Number of teeth of the opposing partner gear: 41 teeth 20x30 (17.60mm/12.55mm) Number of teeth of the opposing partner gear: 40 teeth 20x32 (17.60mm/13.40mm) Number of teeth of the opposing partner gear: 38 teeth If in doubt, simply count the teeth of the gear into which the smaller gear engages. Service: We have over 100 gear variants in stock and can supply the appropriate gears if required! + all alternative sizes always in stock + fast exchange service in case of size deviation For repairs, we will send you an illustrated repair manual (German/English) by email. Advantages: While buying a used speedometer initially saves on repairs, it carries the risk that the gear will also break soon. Storage times and cold temperatures, in particular, further damage the gears. Due to an incorrect choice of material by VDO, all original gears of this type will break over time! Quality: Our gears are meticulously manufactured using injection molding, true to the original design, and are not 3D-printed in-house creations. We collaborate with a manufacturer specializing in the production of plastic gears and a global market leader in repair solutions. The involute tooth geometry is maintained; 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 as the material. These ensure low friction and wear-free operation. If you disassemble the speedometer beforehand, please note that the speedometer needle shaft is very delicate. Grasp the speedometer needle in the center and turn it counterclockwise, pulling gently as you do so. Friction is all that holds the needle on the shaft.
