Looking for info on replace gears for RZ350 Power valve motor. There is one gear inside that is a weak link that always strips in these motors. Looking for a after market gear. On another note I was talking to a machinist he was telling me that there's a process some high performance motor builders use, is kriogenics. That by frezzing components at what ever temp it's done at that the components become stronger buy realiening the molecules he mentioned a company called "300 Below" anyone hear of this process? Anyway I'm tired of buying these motors on ebay if there was a replacement gear that would be great. Or is there another alternative?
