I wish scott would go back to the universal drive on his steamers. My 3 rail Selkirk quit running awhile back and finally found a guy to fix it. The motor pully broke, the drive belt broke and the set screw on the flywheel was too tight and was stripped. The flywheel was just free spinning on the motor shaft. The standard dogbone universal on the flywheel to gear box runs forever. I have a Williams big boy and it has hours of running time and still is in great running condition. If you have many hours on a steamer with the belt drive might be a good thing to check it out. My lionel and mth engines have the same drive as Williams and they run flawlessly smooth.
