Gottlieb System 3 rebuild tutorial request.
vid1900 , I cannot thank you enough for all your guides. I have learned and applied the wisdom you generously and laboriously shared. I’m a gearhead without a garage, so I bought a cadaver Gottlieb DMD machine and rebuilt the heck out of it with your guides and pinrepair.com (donation made) as my new Haynes manuals.
My flippers are never right. I am constantly tinkering with all four of them.
1. Did you ever post a guide to System 3 Flippers? I cannot find it (or System 1).
2. Is there a way to improve the design? The return springs, for example.
3. What is preventing a swap over to aftermarket Stern assemblies?
Looking at the exploded diagram I have a few questions as what I have in my machine is different (and I forget why).
Q1. Circled green.
I have two bolts (#5) holding the flipper shaft (#4) threaded through the flipper lever assembly (#20). Diagram shows one but there are two threaded holes in the PBR replacement assembly. Those screws drive me crazy crazy crazy as I always experience a shift when tightening. I’ve taken to tightening them alternatively in fractions of a turn.
One would make life simpler, but seems like it would push the shaft out of alignment causing drag. The diagram also says three of that bolt is used in the entire assembly and two of those are on the coil stop.
Q2. Circled blue.
Lugs on coil stop side. Goes against what I’ve read here but there might be a good reason. Your recommendation here would be great.
Q3. Circled red.
Upon dissembling I found two of these spring washers between the coil and bracket. Definitely on both lower flippers. Not sure about the upper ones. Scratching my head on that one. Factory or field repair - adding an extra shim might do something.
I’m doing a second complete PF swap (long story) and will be refurbishing all mechs as necessary (or just for fun).
A write-up would be killer, I can take photos if you need.
Thank you for everything. Thank you in advance. Are you posting again?
