    If it's a screeching type noise, it's the motor and/or worm bearings. They need oil.

    This should do the trick, at least it does for me whenever I have a Kato dash 9 that makes that sound. The trick is you have to get way down in there where you can make sure it lubes the bearings. hit it once and give it a try and if it still makes noise hit again and that should usually do it. I use Labelle oil for the gears and this for the screeching noise you described. :)

    That stuff is great. I've been using it for years. JD DeBene turned me on to it.

    Does this work on other Kato diseasels that whine such as the A/K SD-7/SD-9, the F-units, E-units or the RS-2/RSC-2?

    It should work on any locomotive. I basically have both Kato and Atlas locos and used it mainly on my c44-9ws whenever I purchased a used one and it came with the whine, but also used it on one or two Atlas locos with the same problem and it fixed em right up.

    What happens is the shaft, instead of evenly slipping on the inner surfaces of the bearing, sticks to to the surfaces and travels around the bearing instead of rotating smoothly within it. Hence, the squealing/screeching.

    Sounds to me like the shaft has welded to the bearing.

    If you can remove the shaft and bearing, you might be able to separate them and determine weather they can be cleaned up and reinstalled. Examine both parts to see if there are any burs or scores in either one.

    I think that the parts ran dry of lubrication, got heated by friction, expanded and seized up. It may be impossible to separate the shaft and bearing, and both may have to be replaced.

    The big problem may be the availability of those parts.

    Best of luck to you

    Worm gears and motors are readily available from Kato

    AAH....I believe Kato has a good reputation for good quality merchandise. personally, I would contact them first before doing anything that might effect their warranty.

    That's not the typical sound from dry bearings. Normally, the speed of the loco is drastically affected, too (slows way down). Yours seems to be operating at a normal speed. Also, yours doesn't really screech. It IS more of a whine.

    Rolling stock storage ina Tiffany box? Nice! :)

    As for the noise, I would try HALF a drop of oil on the bearing blocks. Nothing to hurt by doing that.

    Your running the locomotive at full speed of a scale what, 200+MPH? It's going to make a lot of noise. You notice it's a bit more quiet at a more realistic speed. Yes, there is noise. But there are goings on inside the locomotive. No N scale locomotive is whisper quiet. There are a lot of gears in there spinning around and meshing with each other. There is nothing wrong with the locomotive. Also, you are operating the locomotive on a hardwood floor and track with molded ballast. I cannot help to think that the hollow area under the track helps amplify any sounds made by the loco. Hardwood floors are also not known for their sound deadening qualities as well. You may not have space for a more permanent set up and this may be the only way you can enjoy your trains. And that's fine. But that environment is just going to amplify any sounds the loco makes. Even on our club layout with foam top and Woodland Scenics form roadbed, there is noise from the locomotives. Nothing like what you are experiencing. But they do make noise. If anything, a little lube on the gears visible on the bottom of the locomotive trucks(a drop no more excess lube attracts dirt) should quiet it down a little.
