An odometer counts milage. The mechanical odometer's gear ratio is allot to calculate the distance a vehivle has travelled. The odometer's shaft spins hundreds of times Everyone mile. The odometer can be calibrated with some consideration resulting in a and accurate milage reading. Peruse on to memorize calibrate an odometer.
Instructions
1. Check the exactness of the odometer. For a manageable on the other hand crude testing course, carefully roll to a cease at a highway mile marker. Draft down the odometer's reading. Propel along the shoulder until reaching the alongside mile marker. Copy down the odometer's reading. This can peerless be accurate to within a tenth of a mile. Advantage calibration tackle for higher rectness.
2. Calculate the odometer's ratio. Many American cars are locate to a 1,000 to 1 ratio. This money that for every 1,000 spins of the output shaft, the odometer dial moves one tenth of a mile. A gear ratio is decisive by adding the quantity of teeth on two gears and dividing the fundamental gear by the moment gear. For instance, provided gear one has 100 teeth and gear two has 20 teeth, the gear ratio is 5:1.
3. Inception calibrating the odometer by disassembling it. A bicycle's odometer is simply a petty rotate placed against the rotate. In a car, 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. 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.
Use fine needle nose pliers to crimp the output shaft as it enters the odometer. This will restrict the spinning of the shaft.5.
