This is a short video going over the steps to repair/rebuilt/refurbish early solid state pinball flipper assemblies, such as those on Stern and Bally games (but this also basically applies to most pinball machines). I go over the process specifically on a Stern Trident and show the specific style of plunger and assembly they’re using, but most games use similar parts. You can use these techniques to rebuild/refurbish pinball flippers on most games.
Also, there’s another thing I don’t cover on the video that may also be a cause for stuck/sticky flippers, and that’s crud around the flipper button. Sometimes the flipper button assembly can be dirty and the button may stick – that can also cause the flippers to not behave properly, so be sure to check and clean the flipper button regularly too!
Are you running into issues where the flipper in your pinball machine occasionally or regularly gets stuck? Here’s a quick trick to identify where the cause may be. The first step is to figure out if it’s an electrical or mechanical problem.
For the second installment of my Pinball Features series, I talk about the iconic element that makes pinball, pinball: The Flippers! How do they work? Has the design changed much? What is an end-of-stroke switch and how does that work? What are the parts of a flipper assembly?
As soon as I thought I had the game operational, I waxed the playfield and got ready to put it back together only to find out one of the flippers was out. This was a rather tricky issue that took a little bit to figure out — not your typical flipper problem, so I thought I’d do a video of it and go through the process of diagnosing why a flipper might not work (on a Bally-35 early solid state game).
Lately there’s been a bit of a hullabaloo (is that how it’s spelled?) regarding coil stops on newer Stern games. I had it happen to me as well, and I made a video to describe what’s happening. It appears whoever is manufacturing the coil stops for Stern has used inferior materials and they prematurely come apart. I’ve reported this to Stern and will let you all know what they are doing about it. I expect this supply issue to be resolved soon and if you encounter this problem, contact Stern support. They should be able to send out replacement coil stops.
The next day I returned with the right parts. Here are two videos covering the repair.
Here are two videos of me completely rebuilding the flippers and flipper assembly on a Gottlieb System 3 pinball machine (Waterworld) – many of this information will basically pertain to most flipper systems on other machines like Bally and WMS, Stern, etc. I go through the whole process of replacing all the major wear parts on the flipper assembly even including the base plate and end-of-stroke switches.
Here’s part 2 (sorry I rarely edit these videos so sometimes my camera breaks it into separate files)
If the above is too slow, check out this time-lapse of rebuilding the flipper:
I got a new pinball machine in the other day and one of the flippers was sticking up. In this video series I go over examining what was wrong and how to address it. There are a number of causes for stuck flippers. The most common cause is a dirty or worn coil sleeve. Also sometimes there can be a hang up with the EOS (end of stroke) switch (more common on Bally/WMS than older Bally or Gottlieb games).
