Williams Pinball Flipper Assemblies 1984-1998

I used some incorrect parts on my Elvira and the Party Monsters (EATPM) pinball flippers. While I was tracking down the proper parts, I ended up doing an exhaustive analysis and comparison of flipper assemblies, sub-assemblies, and individual parts used by Williams between 1984 and 1998.
This video covers all of the core flipper assemblies used in Williams System 9, System 11, and WPC pinball machines, specifically discussing flipper assembly part numbers C-9952 / C-9953, C-11626, C-13174, A-15318, A-15205, and A-15849.

Updates and errata:
- Assembly C-11626 used two different coil stops. The assembly was revised in February 1988 to increase the height of the coil stop, as shown in the C-11626 revision chart at 19:52. Games made before February 1988 used coil stop A-10821; those games were F-14 Tomcat, Fire!, Big Guns, Fire! (Champagne Edition), and Space Station. Later games with C-11626 used coil stop A-12111, which was 1 mm taller. Either coil stop will work in C-11626, but flipper travel will be less than the original design if you use A-12111 in one of those early games.
- Terminator 2 uses assembly C-13174, but is listed at 7:00 as using C-11626.
- Gold Mine is listed as using “System 11” Style assembly C-11626 at 4:38 and 7:00, but Gold Mine is a shuffle bowler, not a pinball.

This is an incredible video of the Williams history for the flippers! Thank you very much for such detailed information about each generation of flipper assembly! It was quite a bunch of information, but super interesting to watch!

Please check. I have a terminator 2, but it is not fliptronics. IS there a way to make sure I get the right rebuild kit? Specify the part number, machine or style? Also, do system 6, etc as I am looking to buy a firepower and cyclone machine.

T2 is one of the early WPC machines that still use the older style flippers. T2 used assembly C-13174. Every parts retailer is different, but you should look for “early WPC”, or the assembly (C-13174), or the date it came out (Jul 1991). …or with this video you could buy each of the parts for C-13174 individually to make sure you get the right parts!
I’ve got T2 listed as using C-11626 at 7:00. That’s incorrect. It used C-13174. I made a note in the errata in the video description.

I don’t know anything before System 9. Cyclone is System 11 and uses C-11626 so this video has you covered there.
