How can you tell what size Pinion gears
I just got a ring and pinion gear (motive) for free from a buddy that claims they are 3:73, but when I looked on the end of the pinion gear their is marking engraved 216 on top and 2.556" on bottom. I tried to count the time the pinion turned around the ring gear and seemed to turn about 3.73 times. Is there anyone that is farmiliar with motive gears and there markings.:wallbash:

The numbers represent the ratio of the gear teeth to the pinion gear in the rear end. You can find this number by counting the teeth on the ring and dividing that number by the number on the pinion and that will be the gear ratio. The higher the number of the gear ratio, the more times your driveshaft will rotate per wheel rotation. 3.73 gears will rotate your driveshaft 3.75 times per one full turn of the wheel, and 4.10 gears will rotate a tad over 4 times per turn of the wheel.
