With the sound off you can hardly hear them. Ken. There is a trick in firearms in which you put toothpaste in the action to smooth it out. It is a mild abrasive. Obviously, you want to clean that out and lube it once it works the way you want. Is that it? Could you describe what you do with locos?

QUOTE: Originally posted by rrinker Labelle sells a nifty 3-pack package of lube that should cover just about anything. Comes with good recommendations on what to use where, as well. To that I added a bottle of their powdered teflon lube - those 4 cover everything I do. If it runs quiet in forward - it's definitely somehting rubbing whent he motor and gear train are loaded in the opposite direction - could be the motor shaft bearings ont he motor itself, or a siderod sticking, or the worm gear thrust washers (remembering that the mechanism is similar to a typical diesel with a central motor and a pair of gear towers). I had a P2K GP-7 that started squealing badly - but only in 1 direction - found a missing washer on one side of one of the worm gears, replaced that, and no more squeak. --Randy
QUOTE: Originally posted by rrinker I'm going to guess it's more of a gear lash issue than a motor drive problem, all three QSI locos I run are fairly quiet, definitely no lack of 'silent drive' type of buzzing - the M1a in particular is TOTALLY silent (well, after I lubed the side rods which squeaked a little) and considering it cost a grand total of $129, was MORE than worth the price. The sound is awesome - but even with the sound OFF (F8) it's a great model. Make sure the loco is lubricated per the instructions, and give it some time to break in. It should quiet down. --Randy
QUOTE: Originally posted by cacole When running on DCC, a buzz from the motor is usually caused by the DCC signal frequency itself interacting with the motor. You can (should be able to) eliminate this by changing the frequency of the signal that goes from the decoder to the motor, but I don't know offhand if the QSI sound decoder offers this option. Unless someone else chimes in with the information, you'll need to consult the Brodway Limited QSI decoder documentation looking for phrases like "quiet drive" or "dither." If I can find anything in the QSI documentation I'll let you know -- but first, I need to download it. ------------------------ Well, I just read through the entire QSI decoder manual that I downloaded from the Broadway Limited site, and I could see no CV to set the decoder's motor frequency. Unless you run your locomotive in reverse more than you do in the forward direction, I wouldn't worry about the buzzing causing any harm to the locomotive. Just don't leave it sitting on the track for an extended period of time with the DCC command station set in reverse, and you should be okay.
