Shopping for a Speedometer Drive Gear
Your speedometer enables you to ensure your safety when driving by allowing you to monitor your driving speeds as you shift from low gears to high gears. In turn, the speedometer drive gear or worm drive gear is a spur gear that meshes with the worm (a gear in the form of a screw) of your speedometer that ensures the accuracy of its speed gauging. When this gear gets worn out, you'll need to replace it. It's also handy for speedometer recalibration purposes.
Pointers for Shopping
- Check the Specs of Your Drive Gear Prospects: You want a speedometer drive gear that's easy to install. It could either come with instructions that make installation easy or tools that assist in streamlining the installation process. Sometimes, it's in a kit that includes the O-ring. Other times, it doesn't include the O-ring and you'll have to buy it separately. Go with the gear that has the most beneficial and favorable specs for your speedometer needs.
- Look for Gears with Great Recalibration Capabilities: The drive gear is mainly used for speedometer recalibration. You might need to recalibrate a jeep's speedometer when you're running larger tires or wheels. That's because your larger wheels will give you an erroneous speedometer readout since it's calibrated for use with your default wheel size. A good drive gear should match your new tire size to allow for instant and effortless recalibration that reduces the margin of error between your bigger tires and speedometer.
- Examine the Materials and Gear Design Used: Speedometer drive gears come with different materials used on them. A stainless steel drive gear provides you with an excellent grip. Hardened steel gears, meanwhile, are great for 1.75 and 3.00millimeter filament, plus they cost less. There are also stainless steel and brass gears (giving you the best of both worlds) and drive gears with extruders or smaller diameters to ensure 35% more power.
- Go for Gears That Ensure Gauge Accuracy: When searching for the right speedometer drive gear for your vehicle, you should get one that makes your odometer and speedometer accurate again. It shouldn't just ensure speedometer accuracy; its recalibration capabilities should extend to your odometer or your gauge for distance traveled. Your odometer is connected to your speedometer accuracy since it bases its measurements along with your speedometer readings as well. They essentially work hand-in-hand.
- Match the Gear with the Speedometer Type: One way to make your speedometer drive gear shopping easier is to ensure fitment with your speedometer type. Research what type of speedometer you have or ask your mechanic about it. The types of speedometers include electronic or programmable speedometers, GPS speedometers, and so forth. Whether it's an OEM speedometer that came with your vehicle or a universal-connection/OBD-II connector speedometer can also alter the type of gear you'll need.
