Fixing and Tuning WPC Flippers

Note: This page is a work in progress. Please help get it to a completed state by adding any useful information to it.

Fixing up the flippers is an important part of making any game play well. If the flippers feel a bit lifeless, it is time to tune them up.

One of the most useful tools for working on flippers is a 3/8" Gearwrench. This wrench has a ratcheting head, which makes it much easier to crank down the flipper bat clamp. You will also need a Philips head screwdriver, a XXX hex wrench, and a small adjustable wrench.

Remove the Flippers

Loosen the flipper clamp nut with your 3/8" wrench. If you are lucky, you will have a locking head on the other end of the shaft. If not, you will need an Allen key to stop it turning. Once the flipper is loose, you can pull it out from the top of the playfield.

Now, loosen and remove the sockect head screws at the rear of the coil. The stop will come off, and you will be able to slide the coil off of the mechanism. If the coil does not slide easily, it has distorted and needs to be replaced.

Next, remove the two screws holding in the EOS switch. The mechanism is now mostly disconnected from the game.

Now you can remove the eight screws that hold the flipper plate to the playfield. The plate will come away.

Inspect and replace if necessary the nylon flipper bushing. The bushing is held in place by three screws that screw into the plate, and locknuts that screw to the protruding threads.

Replace the coil stop, plunger, flipper link, and flipper clamp.

If the EOS switch (stll hanging inside the game) looks bad, replace that too.
