Rebuild a flipper, part 1: strip and inspect

Steps

  • Undo the two bolts holding the coil stop with an Allen key; catch the spring washer before it rolls away.
  • Push the old coil sleeve out with a 5/16" nut driver. It should slide out easily; if it fights you, the coil has been overheated and should be replaced.
  • Fit a new sleeve from the end of the coil away from the solder lugs (always replace the sleeve).
  • Unhook the pawl return spring, loosen the pawl bolt and pull the bat out from the top; remove the pawl with the plunger and link.
  • Check the blue nylon playfield bushing: a cracked stem, internal wear, or a top less than 1/8" above the playfield means replace it (three screws, 1/4" nut driver; tall side up through the playfield, screws firm but not overtightened).
