    ...it sounds like 'plonk', or like it's underwater. Seems to function properly otherwise. Does the rod that strikes the chime need to be replaced, or is it something else? The chime itself is fixed in place, and adjusting the distance travel didn't work. If I manually strike the chime with that rod, I get a true chime sound. Just wanted a second opinion before I go and order a whole new solenoid.

    Where would you adjust the travel distance on a chime unit?

    Could try swapping one chime plunger with another (e.g. the 10s for the 100s) and see if the problem follows the plunger or stays with the chime.

    Is the plunger getting stuck on the foam underneath, and inhibiting its pull through the solenoid?

    Hi DF
    I was adjusting the solenoid position for more/less travel.
    I will try swapping plungers. It seems to strike the chime normally, except for the sound. I'll check the foam issue when I get back home. It just popped up, and sounded fine previously. No moving of machine in-between.
    Thanks

    The beer foam on the bottom is not what I'd call the best idea ever. The plungers heat up and and the beer seal melts onto the plunger and it ends up sticking.

    Are all the chimes doing this or just one particular one?

    #5 4 years ago

    Just the one, and it worked one day, 'plonked' the next. No beer spilled back there that I remember.

    There's a switch on each score relay that fire the chime coil. Worth checking they're clean & gapped.

    Oh, and can the foam just be removed, or should something else be used underneath?

    Will check that also, thanks.

    Interesting. There's no adjustment on those that I've seen. The sleeve pokes up through the top of the chime unit bracket, and then the 'L' bracket holds it in underneath.

    But even so, the plunger will travel the same distance regardless of the position of the solenoid; it's limited by the hitting either the top (chime) or bottom (foam). The strength of the pull could have an effect though.

    Right, the bracket allows for a little travel. Didn't know if hitting the chime at the 'end of stroke' or earlier, would make a difference or not. Not much to it, I know.

    I used something like this I think:

    The old school way is probably beer seal, but it's famous for getting gunked up in the coil sleeves, did you replace the sleeves?

    You need to add something to cushion the plunger when it falls back down. I use a piece of hard rubber I found in a hardware store.

    I certainly didn't mean beer had been spilled on it. Beer seal is what is used under the lockdown bar to seal it against the glass. It's very spongy and it will melt onto the plunger if the plunger gets hot enough. PBR includes it in rebuild kits, and it gets tossed aside immediately by me.

    Either the plunger is gunked or you're not getting enough current to the coil, which would probably be a relay switch problem.

    Thanks all, I will look at tonight and report back. I appreciate it.

    #15 4 years ago

    PBR do chime rebuild kits that have all that is needed to rebuild - pretty cheap as well.

    #16 4 years ago

    Fixed!

    By simply loosening the screws on the bracket that attaches to the back box...it changed the tone of the chime. It could have been a humidity change thing possibly? Anyway, all fixed, and thanks for the chime education!

    Hello

    I've recently learned that I call bells 'chimes'. My apologies, I had been referring to a 100k bell in a '59 Gtb. Sorry for any confusion!

    #19 4 years ago

    Well, I was wondering when you said "in the backbox." Bally put chimes there, but I didn't think Gottlieb ever did. And changing the attachment of a chime unit to a cab wouldn't do much of anything.

    Thanks for the clarification.
