Williams Sys11B - Police Force - Ramp Diverter Mechanism

The easiest option, for some definition of "easiest," is to pull the playfield.

That said, with a knowledgeable helper I was able to do this repair with the playfield half up.

Your problem is most likely that the microswitch, which detects the position of the diverter, has gone bad and needs to be replaced.

Yes easiest way is to just pull the entire playfield out. You do not have to disconnect anything - there is enough slack in the playfield harness. Put a towel or something on the side of the cab then rest the playfield against it. The diverter is in a great spot to clean and service it then.

I have a similar issue as P1 gaining access to the top Underside PF on my WMS Jokerz. (Machine is new to me.) But I can’t seem to visualize your description of how and where you position the Playfield out of the cab. Can you please elaborate? Would there be a pic somewhere?

I followed this link to help repair mine. There is a pic in there to show how to set the pf after pulling it out of the cab.

Bingo!

It is a pretty heavy populated PF for sure. It makes a world of difference if someone will help you lift it out of the game.

I lifted that pf out alone. But it’s heavy.

Get someone to help. Have them stand on the other side and lift straight up and out.

Putting it back in is just as hard too. But that mech cannot be worked on with pf still in the cab.

I also remember having to pull it out and back in a few times to test. I can’t recall why testing outside the cab wasn’t adequate.

These responses are immensely helpful. Many thanks to all! Now I see how it's done. The hardest part will be finding 2 guys to help me lift the PF out of the cab... and then get them to come back to put it back in. I can't lift yet, still healing. I also have a PF alignment issue which this procedure will enable me to repair. The PF pivot bolt on the left side of the cab is bent toward the backbox causing the PF to rest off center at the lockdown bar area. That will be a real challenge because the pivot hole in the cab wood is also damaged/distorted. I'm guessing the machine must have been mishandled in shipment at one point. Maybe a threaded insert? Assuming the stock bolt is a carriage bolt?

I did mine without pulling the playfield all the way out by using a couch cushion on the front of the cabinet. There is enough slack to pull the entire playfield forward about 12"and rest it on the front, which then gives you enough room to work from the side.

Downside to this method is its still a heavy playfield and you need enough strength to get it off the posts it hinges on. I would only recommend this method if you cannot get a helper

This can work and sounds like it works with Police Force. You gotta be real careful about snagging wires, mechs, light sockets or anything else on the cabinet pegs.

Sounds like John from John’s Arcade. I enjoy watching his content, particularly his restoration work. Because he shows most everything throughout the process, including the f-ups we are all capable of making. Which can help others avoid the same f-ups. And these are long videos which makes you appreciate just how much time goes into restorations.
