Fortunately, you don't have to do any backyard engineering or buy expensive race car parts to get a hunting gear ratio, because most vehicles already come with them from the factory! Your car, truck, or SUV is likely already equipped with hunting gears in the differential, transmission, and even the engine timing! This video explains why these special gear ratios are used and how even a 2:1 ratio can still use this beneficial trick!
0:00 • Examples of Hunting Gears
If you've heard of final drive ratios like 3.42, 3.73, 4.10, 4.11, and 4.56, those are all final drive gear ratios that have a hunting gear tooth pattern!
0:23 • Benefits of Hunting Gears
Reduced noise, better break-in, and better distribution of wear are some of the benefits!
0:49 • How Tooth Counts Are Decided
Prime and odd number tooth counts are a staple, as two even tooth count gears will never achieve a hunting gear ratio. Still, even though 9 and 27 are both odd numbers, putting them together would generate a pattern thanks to having 3 in common, so prime numbers really make these ratios work quite often.
1:15 • Not Just Differentials
Transmissions and engine timing components will often use these effective patterns as well!
2:10 • The Downsides
There isn't much negative to say here, but it does take a little extra time to engineer, which costs money and time.
