I took the risk of buying a NOS set of Williams FA2s in a rare road name that's one of my favorites. Came beautiful except the powered unit doesn't move. I've read hear about grease hardening (in the gearbox, I think) and am guessing that's at least part of my issue. I also found, unfortunately, that zinc pest had set in. The drive truck looks shattered and just gripping it caused pieces to break off.
I'm thinking this is repairable but not sure where to begin. I don't want to return the set. Price was quite fair and it's not a set that come up often, so I'm very willing to sink some money into these. Seems like I need at least a whole drive/geared truck assembly. Anyone know if Bachmann or a dealer carries replacements?
Thanks!
