2-1/4″ flipper plunger & link.
This is the new style oval link that started being used by Sega in 1995 on “Batman Forever”.
In my opinion, any machine prior to that, the plunger should have the tapered link.
What’s the difference? well this new link can prevent the plunger from fully contacting the used coil stop.
Everything will still work, but under the right conditions, on the hold circuit (flipper up ball trapped) you will here a metal on metal chatter emanating from your flipper assembly.
This is because the plunger shaft is just starting to contact the stop, but cannot quite, as the “non tapered” link prevents it, so it rattles against it, creating the noise.
These are a little cheaper than the plunger with the tapered link, choice is yours.
This link can be tapered with a Dremel, or a file, if need arises.
Note: Link color may vary, roll pin length may vary.
