flipper coil stops.jpg

#1 4 years ago

My game is a bit over a year old and the left flipper started occasionally sticking in the up position. Opened it up tonight to find brass dust under the flipper mechs and the coil stops torn up. The slug that the plunger hits is completely loose on both left and right flippers. There is no more copper or brass washer left between the slug and the metal of the bracket. That is why the flipper is sticking because the magnetic path is no longer broken by the washer.

This is after a few thousand total games so I have to think those stops were not made very well. I don't have any replacement Stern parts on hand but I do have some new Williams coil stops and they look very close. Does anyone know if they Williams coil stops will work in a Stern game? If not, what is the problem they would cause?

If they physically fit the screw pattern and are the right height (probably don't/aren't) Williams coil stops would work as they should fit the coil sleeve all the same. Where you'll find a problem is that the stop is probably a different length, so your flippers will have a different "up" position.

Well the height was the same, the bolt hole spacing was the same, the slug length was the same - but the bent part of the bracket (where the holes are) is longer so it is not going to work. Bummer since I have a bunch of Williams coil stops....

This is a common problem with the stern coil stops. I have 4 newer stern games and have had to change all of them. The sterns are riveted on a the old Williams ones look welded/soldered on. The sterns just wear out much faster. I usually just change the coil stop and the plunger/slew combo and call it good, just like new.

I never had this happen on a Williams coil stop. I guess the Stern ones are less expensive to make so they pass the savings on to us. Wait - WTF, these Stern coils stops are like 3 times the price of the Williams coil stops.... what a rip off!

Good luck, and now I know what flipper coil stops are!

Just be glad, it's not even a $10 part. At least you don't need this one for Sopranos:
...not THATS a ripoff!

Why would they be $55 for a Sopranos coil stop?

Goddammit I knew I should have bought up all the Sapranos coil stops before pinsplosion!
