I recently had the need to move a TZ out of the house and didn't want to ask anyone for help. So this thread is to explain and show how a pinball machine can be moved if your friends are not available and you don't have a stair climbing dolly. Without a doubt it would have been easier and much quicker to find a friend to help, and I probably should have, but I wanted to prove to myself that it was possible and I didn't need assistance. I found surprisingly little information about a procedure to do this online, so hopefully this thread can help someone. If you have an alternative I didn't consider, post that so others can learn another process.
First - label every connector in the backbox in a permanent way. I also took a video that I reviewed afterwards to be sure I didn't miss anything. I actually labeled every connector in two locations so that I wouldn't have an incident like I've had in the past...
Second - Disconnect and pull all the wires in to the cabinet. Be sure you didn't miss anything such as a ground strap and never force anything.
Third - For my pin, I removed the single bolt on each side holding the hinge to the cabinet. Then remove the bolts holding the head to the cabinet. Finally, unlatch the head and carefully pull it from the cabinet. I set it in its new location.
Fourth - Stand playfield up vertically and secure the playfield wiring harness so that wires are not dangling during removal. I then was able to pull the playfield directly up and out of the machine. Make sure on Williams pins that you are not held up by the spring loaded latch by pushing the playfield as far back as needed to clear. One other option is to make a pulley setup to lift the playfield out vertically or use a hydraulic cart to drop the cabinet down (after removing the legs). Set playfield in new location.
Fifth and final - You are now left with a cabinet. At this point, support the machine with your thigh or a chair while removing the rear legs. Then let the rear down and remove the front legs. Flip the pin on to the back and secure the power cable. Removing the transformer reduces the weight of the cabinet shell even further. I chose to leave it attached and used a four castered furniture dolly to push the pin to the doorway. At this point do what works best for you. I had to go to the garage so I lifted it through the door on to the porch. If you are going down or up stairs, I would feel pretty confident using a hand truck or furniture dolly to move the cabinet shell. I was actually spotted by a neighbor at this point though and even though I said I wanted to do it myself and was building a ramp system to get down the stairs, he lent me a hand to go down the final two stairs.
Then reassemble everything. Reassembly was much quicker than disassembly but be sure to take your time. My one regret is waiting to put the legs back on until everything was reassembled to the cabinet. This is very heavy, especially with a widebody DMD pin. One other tip I used was to lay the head on a chair behind the cabinet and stuff the wires back up through the pedestal and through the head. I would not hesitate to use this technique again, but I may only remove the head this time to clear the doorway and use a dolly with two people to get down to the gameroom. I'm attaching one picture showing the pieces, sorry I don't have more at this time but I can take more the next time I do this. Hopefully this helps someone out there.
