Although this seems like a small thing, when changing out pinion and spur gears the proper mesh is terribly crucial to your cars performance. Having your gears too tight will result in sluggish speeds, shorter run times, shorter gear life, and unneeded stress on the motor and transmission. With too loss of a mesh you will clicking the entire time running the car, along with louder clicking under heavy throttle and heavy braking. The loose mesh is much less damaging to your car than tight mesh but equally aggravating and just as damaging to the gears themselves. to properly mesh your gears when you are replacing the gears, first always replace both pinion and spur gears. I know it seems wrong to think that the metal gear would get worn down, but if you run the same pinion gear and only replace the spur gear a few times you will see two things. First you see that which each spur gear you install the longevity decreases, and second, if you look at the pinion gear after several rounds of spur gears you will see it no longer looks like a gear, it actually looks like a saw blade. After you have replaced both the spur and pinion and you are ready to set the mesh follow these two steps.

1. Make sure that the peaks of the gears are not touching the valleys.

2. Leave the smallest of space in between the teeth of the gears to allow the smallest wiggle room
