Main thing is before u even start anything take lot and lot of pics of everything from on end too the other top and bottom ,plus what I do is too make up a form board then draw out the playfield it self just so u can put all the parts where they go so u don't lose them and too know where they go ,then I tape and mark all parts too ,if anything u can always go back too the pics if u get lost

When I did my first swap not only did I take tons of photos but I stuck the parts in ziplock bags with the order number of removal. So I may start with the right sling, that would be bag one and the left bag two. When reassembling I would just reverse order. Had about 60 numbered steps.

Look through some of the HEP thread and other restoration threads where playfield swaps have been documented. The tips in those threads are invaluable.

Don't forget about using tracing paper for dimpling and drill holes and keeping track of the t-nut sizes.

Not sure how different a PF swap is between an 80’s Williams and a 70’s Gottlieb, but here’s a couple pics from my recent swap. I drew a rough sketch of the underside PF components on cardboard and used that to keep all the screws that hold everything down. Then I pulled all the staples, placed the new PF next to the old, and slid everything over a little at a time.

I drew the GI wiring on the cardboard too-in a different color-to help with getting that in the right spot. Restapled the wiring and screwed the components back down.

I’m sure I’m forgetting a bunch of details and I’m not good at taking “in progress” pics, but hope this helps.

I agree that you need to document the crap out of it and be methodical. That really does make it go smooth.

In addition to the steps above with tons of pictures, notes, labeling, you’re going to want to clean and rebuild mechanisms before transferring to the new playfield.

So flipper assemblies, pop bumpers, drop targets will all need to be desoldered and disassembled.

You really should remove and clean the wire harness too.

Usually #6, #8 or #10. See what size screw fits there.

Most likely.

I wouldn't bother reusing the old lamp sockets. I would install all brand new sockets for reliability.

For sides look here:

I used that on Elvira. It should work on PinBot.

For the back, maybe this:

Might want to email and find out.

Make sure you clean any and everything that goes from the old playfield to the new. Consider tossing old light sockets because in a PinBot they are about 35 years old. Look at some of dmacy 's most excellent swap threads. Use Pinside as a resource. Make a thread, document your process, ask questions, and LISTEN to experience.

Be prepared for this to take months and take your time.

REPLACE THEM! Do a little more digging, they should all be available. If there is a style you cant find, post a pic here and we will steer you to the source.

And Im dealing with cloth harnesses on EMs shutter at the though of washing the harness.

Currently I have 4 harnesses in big heaps in boxes, the pf restorer guys/gals take too long. Not having documented any of it... once you do 20+ pf swaps it gets a lot easier.

for the 8449 pbr offers the 2916 with the extra insulated tab for diode. You just flatten the tab and it will fit the bill. Steve will sell you diodes separately.

for the 8338 it looks like the 1/2 bracket 4762 from pbr
