Can this be turned on a lathe?

If the gear is hardened, it will probably only be locally flame hardened in the area of the teeth. Since you appear not to be messing with the teeth it shouldn't be a problem.

Yes its easy to machine in a lathe, use a collet to hold the part by the gear side. No the collet wont hurt the gear teeth. you should be able to machine it, doens't look like it has been harden. As for the cutting tool hitting the gaps, dont worry about it, just go slow with your feed, the speed the cutting tool moves at. You could probably get away with an rpm of 100 or a little more. Thats what i would do. Any questions or complication just ask.
