Williams #5602 Brass Niagara noisy motor problem

You can find 5 pole Mabuchi 555s on Ebay all day long for small money. It would be an upgrade over the 550 and not require any modifications. These engines typically run like a watch. Try the Mabuchi first.

Pete, thanks for the help!....I looked at the 555's. The only difference I can see is the shaft length is a just a wee bit shorter than the OE 550...I might need to scoot the motor mount forward, but looking at the relation between where the motor will sit and where the body is, I think there is room to bring the motor forward...that's the only difference that I can see. Im pretty sure I can split the difference between how much driveshaft engagement, and how Ill have to scoot the motor forward....Im gonna get the 555 like you suggested, 5 poles has to be better than 3!...thank you sir!....

Here is one with a 19mm shaft.

Thanks again Pete!.....forgive me, I had a senior moment..I misspelled Mabuchi when I searched...I just ordered that motor from your link...man...getting old sucks!...I was like DUH!!!!

Say, that looks like a great deal; I never think to look under "consumer electronics" for train-related stuff...

As I get older thinking has become harder and harder...that's why before I go makin a mess out of something, I will ask on this forum. lots of good guys/gals on here help me out a lot!....that motor that Pete linked up will be a simple bolt in....no hacking required!...Im a proud member of the Citizens Against Train Hacking!

The Mabuchis are no Pittmans, but they seem to do the job. Probably don't have the life span, either, but most will outlast us in typical usage/mileage. My Williams brass seems to vary in noisiness; most are pretty quiet, but I have a Challenger that is noisy, even after a motor swap (another Mabuchi), though better. It originally did a decent Pullmor imitation.

My Weaver Dreyfuss (also a Samhongsa) was noisy until I opened it up and saw that the motor was sagging and it was a U-joint making the noise. Shimmed the motor and got rid of the noise - plus averting a possible early part failure in the future. Good to watch.

Unfortunately, the sagging motor situation was not the noise-maker in the Challenger. Brass is a sounding "board", anyway. So that's why they make bells out of it!

D500, I thought I had an issue with something other than the motor, although the loco ran around the track fine, slow speeds, high speeds, didn't matter......I didn't have a control issue or anything binding or drooping. On the rollers, I took the motor mount screws out, wrapped the motor in a rubber glove, and used a zip tie just to snug the motor down, and all the noise went away......So I disconnected the motor, and ran it in the palm of my hand and it carried on a like Sesna getting ready to take off. I couldn't see any physical evidence other than this particular Mabuchi looks a little funny the way the can was coined. it appears to taper more than other Mabuchi motors I have.....who knows...maybe I got a Friday or Monday motor where the press operator was hung over.....Either way, like Pete found for me...15 bucks, Ill run with Mabuchi for now....Ill let Yall know how it goes once the motor gets here sometime next week.....thanks for your input D500

new 555 motor came in today, bolted it in, soldered two wires, ran like a champ.....Smooth and quiet! Thanks for your help on that one Pete! took all of 5 minutes to install and get it back on the track....job done

Can the full model number of the replacement motor be posted?  Thanks

Thanks for the info - may have to replace the motor in my unit.

When shopping for motors look for ones listed for 12-24 volts. Some are listed for 6 volts and will draw too much current and damage whatever is driving it.
