Is your speedometer working properly?

Having a problem with your speedometer not reading accurately and having trouble recalibrating it yourself? Did you get a ticket for speeding or may be charged with reckless driving when you know that you were abiding by the speed limit, then don’t worry there are many local shops that can help? Having a working speedometer is very important because you want to know exactly how fast you are going.

There are many shops out there that can help with speedometer calibration, but the question is which is the best one for you. You always want to look for one that is certified and know what they are doing. You want to find a calibration service that is highly accurate and offer a quick turnaround. Speedometer calibration cost will depend on where you take your vehicle. Most speedometer calibrations will cost about $50-100 but some shops may charge more. The professional mechanic will measure the different speed intervals by attaching a dynamometer to your vehicle which will measure the power output of an engine. They will first measure it at different speed intervals and then they will record any differences between your vehicle’s speedometer reading and the correct speed. If a place gives you a certificate that is 100 percent accurate at every speed be very skeptical because there should be some variation, even if it’s small.

Any great traffic lawyer knows where to get a speedometer calibration done, so talk to them before finding your own shop. Some courts will advise you to get one done, but some courts will use it as weak evidence, make sure who your judge is and if they will use it as credible evidence. Speedometer calibration certificates can or may not be helpful. If your speedometer reads HIGHER than the actual speed that doesn’t help you in any way. If your speedometer reads LOWER than the actual speed, it may help. Speedometer calibrations are usually helpful to make your punishment less severe. It can also help take a reckless driving charge or speeding ticket to nonmoving violations.

If are not sure if your speedometer is reading correctly then go to a company like Safety Restore, they have professional technicians that can help with getting your speedometer to read correctly again. Safety Restore will get your vehicle in and out of the shop in no time and save you lots of your time and money. Call them and have your speedometer calibration done today.

Calibrating Mechanical Speedometer

Calibrating Mechanical Speedometer

The vehicles speedometer has the job of giving an accurate estimation of the speed we are driving at any given moment. Cars coming from a dealer have the speedometer already calibrated to the vehicle’s stock parts. However, if particular parts are changed, like the cars tires, the speedometer needs to be calibrated. Otherwise, you will be given the incorrect speed. Cars that are salvage will also need to get calibration.


A dealer may charge a large amount, so some decide to tackle this themselves. If you have a mechanical speedometer, Here are a few simple steps on how to do a speedometer adjustment.


If you have a mechanical speedometer you would start by opening the vehicle’s hood and locating the transmission. Next, unscrew the speedometer cable and unscrew the bolt holding the gear housing cover. After removing the plate, you will see two gears. Count the number of teeth the gears have and remember it for later. Next, get the diameter of the tire and divide 20,168 by the tire’s diameter. This is the tire’s revolutions per mile. Multiply this by the amount of teeth your gears have and multiply again by the vehicle’s axle ratio (which can be found in the vehicles supporting documents). Purchase the necessary driven gear for your vehicle. Remove the old driven gear by pulling it out of its clips and clip in the new driven gear. Secure the gear housing cover and the speedometer cable back.


However, if you aren’t handy with cars, don’t have the time, or just need help, it may be best to take it to a professional. They will make sure it is done correctly and safely.

How to Test Speedometer Calibration

how to test speedometer calibration

A vehicle’s computer reads the magnetic field pulses in order to determine the rotational speed of the driveshaft. This determines the speed at which the vehicle is going. If you suspect that your speedometer is giving the incorrect readings, here is how to test speedometer calibration.

First, a measured mile is required. Interstate highways and some country roads have mile markers but this method should only be down in a safe manner. Before beginning driving the mile, take note of the mileage the odometer has. Reset the trip odometer to 0.0. Drive a mile according to the mile markers or your measure mile. Then take note of the reading on the odometer. If the odometer is saying that you drove more than a mile, then it is calculating a faster speed than your actual speed. Similarly, if it is displaying that you drove under a mile, then it is calculating that you driving slower than you actually are.

Now that you know how to test speedometer calibration, you can take the next step and calibrate it. However, if you are unable to fix the issue, it is a good idea to bring it to a professional like Safety Restore. Safety Restore is a company that specializes in post accident repair.

How To Do Speedometer Calibration

How To Do Speedometer Calibration

Imagine driving down the road, and you are pulled over for going over the speed limit. However, your vehicle was telling you that you were driving at the correct speed. This may be due to your vehicles speedometer calibration. If you have recently changed a stock part on your vehicle, such as the tires, the calibration may be off, resulting in the vehicle giving you a different reading. For example, switching to larger tires may give you a slower speed reading (which would be the case of you being pulled over for speeding). Smaller tires would give you a faster reading. In this case, you would need to learn how to do speedometer calibration.

If you have an electric speedometer, the process is simple. All you need to do is determine the distance your vehicle has to drive in order to properly calibrate. This number can be found in the vehicles supporting documents. Press the calibration button which is located on the speedometer, start the vehicle, and then release that button. Press the button again and go on the test drive. Once you have driven the required distance, press the button once more and speedometer will calibrate itself.

After you know to do speedometer calibration, but you notice that it is still not giving you the correct reading, or the gauge is not working, the speedometer may need to get repaired. Safety Restore is a post accident restoration company that can help with your speedometer repair. Safety Restore can help rebuilding tachometer gauge, oil gauge repair, temperature gauge repair, gas gauge repair, and the car odometer repair. They can fix it all!

Who Does Speedometer Calibration ?

Who Does Speedometer Calibration ?

A speedometer indicates how fast the vehicle is traveling at any given moment. The odometer tells us how far the vehicle has traveled. They work hand in hand to determine if any services are needed, and to help keep you driving safely on the road. Having a properly calibrated speedometer is very important when your vehicle is on the road. If you are ever pulled over and told that you have been speeding, but your speedometer said that you were in fact driving the speed limit, you can still get a ticket. This is because, by the design, the speedometer is accurate by law. Federal standards in the United States allow a maximum of 5 mph error plus-or-minus. Tire diameter, tire wear, tire temperature, pressure, vehicle load, and differential gearing can all have an effect of the speedometers reading.
Also, if you have bought a salvage car or got a speedometer from a different vehicle to put into another, the mileage needs to be adjusted. But who does speedometer calibration?

The vehicles cluster, is also referred to as the vehicle’s speedometer. It displays the tachometer gauge, odometer gauge, gas/fuel, gauge, temperature gauge, as well as transmission gauge. If you notice that there may be an issue with the speedometer like it giving incorrect reading, sticking, fluttering, or just not working, then you may need to get the speedometer repair or calibrated. What is speedometer calibration?


A speedometer is calibrated to ensure that the magnetic field torque reads and displays the correct speed of the vehicle. It takes into account the gear ratio of the drive cable, the tires diameter, as well as the drive ratio in the differential. If any of these are changed, the speedometer needs to be calibrated for those changes. The easiest way to calibrate the speedometer is to modify the magnetic field’s strength. This is done by using an electromagnet to adjust to match the input from the device’s drive cable.

Driving with a speedometer all your life, you may know the basics of what it does and shows. However, you may not know the various components of the gauge, or how it came to be in the first place.

The speedometer, or speed meter, on a vehicle is defined as an instrument that measures and then displays the immediate speed of a vehicle. Speedometers are now universally installed in all automobiles, but this was not always so. They became available in the 1900s, and became standard equipment right around 1910. Different types of machinery have specific names for the speedometers they are equipped with. For example, on a boat the termination would be a pit log. An airspeed indicator is the term used to apply to aircraft.

A man named Charles Babbage is given the credit for creating an early prototype of the speedometer, which was intended for locomotives. In 1888, the electric speedometer was invented by a Croatian named Josip Belusic, and it was originally named a velocimeter. In 1902, a patent for a speedometer was created by a man named Otto Schultze.

The basic operation of the device is simple. The speedometer uses a rotating flexible cable that is usually driven by gears linked to the output of the transmission on the vehicle. When a vehicle is moving, a speedometer cable is turned by the speedometer gear assembly, which then turns the speedometer mechanism itself. A small permanent magnet that is attached to the speedometer cable works with a small aluminum cup that is fixed to the shaft of the pointer on the analogue speedometer instrument. The changing magnetic field creates eddy currents in the cup as the magnet rotates near the cup. The eddy currents on their own create another magnetic field. This results in the magnet exerting a torque on the cup, pulling it–and the speedometer pointer–in the direction of its rotation with no mechanical relationship between them.

When a speedometer stops working, a car speedometer calibration may be necessary. The company Safety Restore works with instrument clusters and speedometer gauges for all makes and models of vehicles. Whether the speedometer gauge is getting stuck or not working, the tachometer gauge is stuck, or the oil gauge is giving a wrong reading, the car speedometer calibration service by Safety Restore is able to help!
