Heres the gear cutter compared to the original pinions teeth taken on the unworn parts , the cut new one matched as well.

The photo of the three pinions side by side with the new one,the new one gives the appearance of a deeper cut as the shaft is thicker so it has cut deeper into that part . The original shaft was supposed to be 15mm approx but the new one is 17.4mm.

The cutter in the second photo looks off but that is just shadow caused by the flash.

You can cut the groove by holding it in the mill spindle and using it like a lathe with a parting tool clamped to the bed on a block. Make the tool from a broken hacksaw blade and clamp it with no more overhang than the depth of the slot so it will be nice and rigid.

I was going to suggest thinning down the end of a parting tool, but there's more than one way to skin a cat!
