I bought the ON30 two truck Shay a few years ago and stored it without running it as I had no facilities to test run it. Some two months ago I ran it for the first time on an HO layout at my local Hobbyshop, and was overwhelmed with it. This run was for approximately three minutes! Yesterday I managed a five minute run on a two metre test track at another toy shop and was dismayed that after four or five runs trouble occured and the rear truck stopped running. On close investigation I found that the drive crown gear was loose on the shaft. I epoxied this and on reassembly discovered a tight spot as I rotated the wheels. A magnifier revealed that the gear was split and so was the connector on the shaft (the one I had tried to epoxy). Needless to say I was devastated! What do I do now? It seems to be something I cannot fix, and I am here in South Africa far away from help. I don't know who to approach. Can anyone advise me what to do? I'm 76 years old and need help fast so that I can get to enjoy this delightful model. Thanking someone in anticipation - John van Vledder - jhvanvledder@gmail.com
