So how do you identify them?

These components are easy to identify just by the shape of them.  The pinion kind of looks like a bolt that has a flared head on one of the ends.  The pinion actually fits onto the ring which looks like a circle that has crescent shaped teeth.  Most of the time, these parts will look alike but they will have a different ratio as well as a few other differences that are more subtle.  When you want to increase the performance of your rig, changing these out can be one of the simplest ways.

If you are trying to identify these parts by ratio and measurement then you will need to separate them so that you will be able to take their measurements.  Using calipers, get the measurements of both the pinion and the ring.  You will need the diameter of them precise to within a tenth of an inch.  Next, you will need a count of the teeth on both of them.  In order to figure out the ratio, take the number of the teeth that the pinion has and then divide that by the number that the rings has.

Use these measurements to find the sets that match.  The ratio and size between the pinion and the ring are typically unique to a part set and this can be utilized to locate the manufacturer when the manufacturer’s stamped code is no longer readable. 

All of the rings and pinions made by G2 will come in a set.
