Pulled out my Lionel set from my youth (1950's) and am currently renovating it. My number 140 banjo signal was working, but now is not working as before. It runs well at 9-10 volts, however when I kick it up to over 10, the drum slows down, eventually stopping. There is a noticeable growling sound as the voltage increases (and it gets quite loud). I took the drum apart and cleaned the inside of the drum with alcohol. My manual states there is no lubrication required, but I put a very small drop of sewing machine oil down the shaft hole of the coil. I also made certain the rubber washer with the three nubs on it that engages the drum was clean and free of oil. I cannot detect any binding anywhere. Is my best bet to buy (if I can find one) a new washer with the three nubs? I am currently running the signal continuously and does seem to be getting slightly better. Suggestions please!!

A shake of powered graphite in the drum will help. Do not use any oil on this accessory. The oil you put in the coil will only gum up and impede operation.
I thank both of you for the help.....will clean out the oil and buy the new washers.
If you look in the drum where the pin is, at the bottom you can scribe a pattern into the bottom in the shape of a pie, helps little fingers get a grip. You can use a exacto knife.

I like to clean out the shaft hole that is in the center of the coil with a drill bit. Select a bit that just fits. Use your fingers or a pin vise to hold the bit and turn it in the hole to clean out any rust and gunk. You don't want to enlarge the hole, just clean out the junk. Often there will be grime and some rust.
I do this with other, similar mechanisms too.
IMHO, the mechanism getting noisy as you raise the voltage isn't unusual or a sign of a problem.

Got a few on order (in case one or more are not made well enough). Thanks!

Cleaned out any oil/residue with an electronics cleaner (dries with no residue). Ordered the new gasket and will put a little graphite in it when the gasket arrives. Thank you!
HI, I hope I am able to get a little help or it might be too late. Anyway I have a #140 and while taking it apart to clean the back plate came off and the wrapped cloth looking wire came out. My question is, how far does that wire need to be in for the signal to work?Thanks.
