Not meaning to resurrect an old thread, but I need info on repowering 1 of these 4-8-4 northerns from bachmann. It's 1 of there lower class engines I picked up dirt cheap, and now I know why. When 1st ran, she was great, with no load. After a brief, and I do mean brief, traction test, all wheels out of quarter. Upon exam, the plastic gear sets between the drive wheels were cracked.:curse: I managed to get them back into quarter and used a lil super glue on the gear set to keep it in quarter. I filed down the frame just a lil, where the paint meets the drives, and the joints of my super glue to put them back into round. :thumb:
Now, she'll stay in quarter and runs good, but I won't chance putting it on traction test. I would rather regear the whole thing. The whole body is in excellent condition, no parts missing or bent on engine and tender. I want to use her to pull my consist of riverossi hvywghts, cal limited, all nine cars (2 transcontinental duplex sleepers included, 1 B&O and 1 Blue Comet). Ironically, the Blue Comet never had any sleepers, but she looks good.
