That's what we are using and putting a snug fitting pin in the ID of the gear and then running the indicator off the face. Are we on the right track? (Thanks!)

Assuming that the form of the hole is good enough to provide a stable datum axis and the hole/pin fit has no obvious play to distort your measurement, you are on a very solid track in my opinion.
If the item being checked is a simple right angle, you can check it with an indi-square and an indicator of the necessary accuracy. Setup the object to be checked on a surface plate, and run the indicator (attached to the indi-square) up and down the surface you are checking.
