Downloads Positive values result in thicker teeth, as if your cutting tool did not cut to a full depth, while negative values result in thinner teeth. GEARING Simple gearing changes to the pinion gear, spur gear changes, and with some vehicles, ring and pinion gear changes all affect the speed, acceleration/punch, run times and temps. Pitch conversion table. So far I have tried 14t and 16t (one smaller and one larger than the stock 15t) and I can't get either one to work using any combination of the three pre-set holes. For example, if the gear has 28 teeth: 28 / 6 = 4.67. The world of gears is very interesting to me because of the rich history they have, their interesting complexities, their apparent simplicity, and how a new gear train feels when processed and meshed just right.
