2. Calculate the odometer's ratio. Many American cars are allot to a 1,000 to One ratio. This money that for every 1,000 spins of the output shaft, the odometer dial moves one tenth of a mile. Interpret on to memorize calibrate an odometer.
Instructions
1. Probation the precision of the odometer. For a light on the contrary crude testing course, carefully roll to a site at a highway mile marker. Compose down the odometer's reading. Ride along the shoulder until reaching the succeeding mile marker. Correspond down the odometer's reading. This can solitary be accurate to within a tenth of a mile. Appropriateness calibration system for higher precision.
An odometer counts milage. The mechanical odometer's gear ratio is place to calculate the distance a motorcar has travelled. The odometer's shaft spins hundreds of times Everyone mile. The odometer can be calibrated with some carefulness resulting in a extra accurate milage reading. A gear ratio is bent by adding the quantity of teeth on two gears and dividing the headmost gear by the moment gear. For instance, whether gear one has One hundred teeth and gear two has Twenty teeth, the gear ratio is 5:1.
3. Open calibrating the odometer by disassembling it. A bicycle's odometer is simply a diminutive shove placed against the spin. In a automobile, the odometer spins within a metal housing. The mechanism of a mechanical odometer is a series of worm gears that turn the subsequent gear one tooth at a time. The final gear turns the one tenth of a mile indicator which in turn moves the one mile, ten mile and so on.
4. Adjust the odometer's gear ratio. This can be done by interrupting the spinning of the output shaft connected to the transmission. Use fine needle nose pliers to crimp the output shaft as it enters the odometer. This will restrict the spinning of the shaft.
5. Calibrate a computerized odometer using calibration instruments. This requires an investment of time and money. This equipment is not readily available to the public as it can be used to re-set a used car's odometer and thus defraud a buyer. The diagnostics in a car dealership can easily pick up tampering.
