So now that we have this thing, my first question to the group is how do you time the side rods? It came to us with rods off one truck. We can get one side on but the other has a 1 inch difference in spacing between axles. I am sure there is an easy fix but I have not found it yet. Lol Does Logan still exist? Thanks Bill |

The cranks should be keyed to the axles. I'd recommend looking for a sheared or missing key. It's possible a crank spun on the axle, misaligning the crank pin for the side rod. Edit: First step is to rotate one axle until the cranks are aligned. If you are still having issues, see above. |

Looking at the second photo, that ain't gonna work. If you have a side rod on with the wheels "out of time", you've effectively locked the wheels in place - nothin' gonna turn, simple geometry I know nothing about 45 tonners or any critters for that matter, but.... Can you jack the end of the truck that doesn't have the traction motor and turn the wheel to get it in time with the powered wheel set? |

Are you sure those are the correct rods? Measure the center distance of the axles and compare to the rod center distance. |

Did you rotate one of the axles between taking the left hand and right hand side photos? If not, my money is still on a missing or sheared key. Something is definitely off. Look closely at the axle centers... you’ll be able to see the keys pretty clearly. |

I agree with Joe, if the locomotive has not been moved between the photos, the indexing of the pins and counterweights on the inboard axle looks suspect. PC |

The counterweights and crankpins locations should match when looking at the truck from either side. And then maybe 90-degrees different from side to side much like a steam engine. I would take the one rod off that you got installed and then check to see if one of the four counterweights has a shared or missing pin. Then follow the directions given above. I would also measure the rods and the center to center of the axles just to make sure everything matches. |

Could the traction motor be wired to a 2 banger diesel welder to slowly rotate the motor? UP turbine 18 was used that way till the welder seized up at the Kansas scrapyard. Robert |

Drag the loco about 18 inches and try again. hopefully the rod ON the engine will be at the top or bottom. Then the other rod should slide on a little easier. |

Seems that the axles are simply "out of phase". To be expected when a locomotive with side rods is transported with the side rods removed. From the supplied photos there is no evidence of a "sheared key" (that would be quite evident). So, block one axle so it can't "turn" very much, then jack up the other axle (with appropriate blocking between the truck frame and the journal box). Then rotate the "jacked up axle" until the side rods "fit". If the keying between the axle shaft and the counterweight/crankpin was significantly damaged I would expect the journal brasses to be "hosed"..... Or just "jam" the side rods in place, the wheels will just "slip" on the rails until things are "happy" again. Cheers, Kevin. |
