1 Twilight Zone Shop Out Guide

Few hints before you get started. Make sure everything works, that way if you get to the end and something doesn't work, you know it's your fault. And take plenty of pictures - go overboard, you can always delete them after things are back together. There are pictures online at www.theteardown.com.

2 Parts to have on hand

  • If you haven't already, replace the clock target and the slot machine target with the reinforced targets. These are available from several Pinball Parts Suppliers.
  • Bulbs - thirty or so #44 or #47
  • twenty #555 a seven #906 flashers
  • Rubber ring kit - see chart at end
  • Replacements for anything that is obviously broken, pop bumpers, for example.

3 Start

    - use Test 18 in the diagnostics to empty the gumball machine!
  2. Raise playfield and disconnect wires to ramps
    - (basically any wire running though a hole to the top of the playfield). Make sure all wires can come up through the holes without any encumbrances.
    - Label connectors so they will be easier to reconnect. I use a sharpie permanent ink pen and use the letters of the alphabet - a,b,c...
    - Make sure you label the connectors to the mini playfield and don't mix them up

    Remove the plastic - 3/8 inch phillips head screw /w star washer and thick washer
    There should now be access to pull the optical switch harness for the ramp through the playfield, so pull it.
  18. Remove the two #2 phillips screws that hold the ramp entry into the wood.
    Note that the screws DO NOT hold down the flap.
    There is a leg on the right side of the ramp. Remove the screw that holds this leg to the top of the 3 ball lock mechanism. On EARLY protection units there is a 1/4 inch plastic spacer between the leg and the lock roof. DO NOT LOOSE THE SPACER!

    Loosen but DO NOT REMOVE the 3 screws that hold the plastic to the wood rail. Remove the plastic (you don't really need to remove the plastic, just get the wires out from under the plastic, you can remove it when the ramp is off).
