Miracles never cease. In the mail today, I received one of the aforementioned wheelsets, complete with a brand new machined brass gear. I am very impressed. Kudos to Athearn from me.
Of course, I was personnaly never that turned off by the original gear problems. It is not like they went to some fly by night outfit to have them made (Samhongsa) after all. And they got one order of replacement wheelsets for the Mikes in before the buyout. And NWSL bailed us all out. And they also did say they were getting another order of wheelsets for the Mikes about the time I first needed a Pacific wheelset. Maybe…
So, if you need a Pacific wheelset, I would get on the horn.
