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)
