I have a 646 Hudson steam engine that I've been running with my set since 1953. The set comes out now just briefly for the holidays, (space is limited). This year while cleaning and lubricating my equipment I noticed that there is a gear on the left side of the engine between the most forward and center of two of the six large wheels in the center of the engine that seems to wobble on the post it rides on. The post looks like its ok. It just seems to be the hole in the gear that has opened up considerably. This gear, about the size of a quarter was just "placed" on this shaft, however with the large wheels in place it is captive and cannot be removed from the shaft without removing these two of the six wheels in the center of the engine. The wheels seem to have been pressed on to their shafts and I don't want to force anything. The engine still runs well, however this gear wobbles as it drives the other wheel. Luckily, the teeth on the gear as well as the teeth on the wheels are not chewed yet, but if this situation persists I'm sure they will be. I'm certain that this can only get worse if neglected. I have always maintained and even rebuilt many pieces of my set over the years but I've never disassembled an engine drive before. Can anyone more familiar with this kind of dissasembly please advise me as to how to go about removing these driving wheels without damaging the engine. Or if there is a more appropriate newsgroup I might present this question to I would very much appreciate being advised of that as well. Thanks very much, Lenny
