Got the Nash box disassembled last night. Looks like the damage is limited to both third gears, and one bearing that injested some trash. The design is reasonably straightforward to disassemble, but I spent 95% of my time just dealing with the snap rings. I'm assuming that some of the choices for snap ring sizes were to commonize parts, but some of the rings are definitely overkill. My biggest problem was dealing with the snap rings with my snap ring tool. Does someone have a different design tool they can recommend to save me a lot of time and aggravation when it's time for assembly?
I greatly appreciate any constructive suggestions.
