I obtained one for little money, good shell, good mechanics, brushes and armature were in good shape, gears were a bit dry so all areas received some lubrications as needed. The interior certainly Not like my other switchers 623 624 6250 etc are really basic by comparison. So I read in Tandem Associates that this model was designed to run well on tighter radius of 027 gauge track but they will run equally well on O gauge track.
my layout, all 0 gauge tubular Lionel and super K line 031 curves and 022 switches are perfect for traditional postwar.
So testing her out I found that it doesn't like the 031 and 022, derails. No other of my short chassis switchers do this. Oh well, so I looked at it again and it seems that the power truck does not have enough swing or flexibility, or maybe it’s not swinging freely. Seems like it’s narrow. Question: is there possibly a nylon washer that may solve this issue? I didn’t see one. Hmmm. I am under the assumption that the upper truck is rubbing on the chassis. Maybe a center spring in this area is missing? What I know is missing right now is my (loaned out )Greenberg Repair and Operating Manual for Lionel trains 1945-1969. I’ve not had the pleasure of owning and maintaining the simpler late postwar switchers. Any help, advice appreciated.
thank you.
