Start with a two-gear train. To be able to determine a gear ratio, you must have at least two gears attached to each other â this is called a gear train.. Usually, the first gear is a drive gear attached to the motor shaft and the second is a driven gear attached to the load shaft.. Divide the teeth numbers of the drive and driven gears. The important thing to remember when dealing with gear trains with more than two gears is that only the driver and driven gears (usually the first and last ones) matter. In other words, the idler gears don't affect the gear ratio of the overall train at all.
Step 3: Select Your New Gear Ratio. Using our Gear Ratio Finder and Engine RPM Calculator, select the appropriate gear ratio for your application. Step 4: Check If The New Gears Jump the Carrier Break. If your new gear ratio is within the same carrier range as the stock gears, then standard gears will work fine. If your current gear ratio is on the low carrier and your new gears are on the high carrier, then you will need to change the carrier, use a ring gear spacer, or find thick gears.
