Twilight Zone Shop Guide

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.

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.

    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!

29. Gently left up on the ramp to gain access to the rear playfield plastic.
    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).

       Note, on my machine I had to move the divertor that sends balls to the gumball VUK so I could access the middle screw.
