Quoted from A_J_B:Joined the Star Wars Premium club (4th pin owned). Game is great and I'm glad they did another run however, i have run into a problem. After playing about 10 games the left flipper drooped about 3/4 to 1 inch below the alignment divot. Being that I'm still new to this pinball stuff (lots of fun with pins at the house now), I contacted Stern and the provided me with instructions on how to realign the flipper (loosen the setscrew, realign the flipper, and tighten). I followed the instructions but now the bracket on the plunger/crank assembly doesn't hold the flipper shaft at all (flipper slip is occurring). I torqued the setscrew it about as much as I could (even broke the washer that goes between the bracket and the screw) but it still doesn't hold it all.
I'm not sure what else to do besides ask Stern to send me a new plunger/crank assembly and replace the whole mech. I'm not sure if one of the brackets is bent or if the flipper shaft was made incorrectly and is just too small to be held by the assembly.
Does anybody have any other suggestions or have had this happen before (on Star Wars or another new Stern machine)?
Thanks for the help in advance!

Now that you've been staring at the flipper mechanisms a bit, you are a little bit more familiar with the components. I guess it is possible that there was some defect at your plunger mechanism (which certainly is not the common).
While you can certainly inquire to Stern to replace the plunger mechanism, which it sounds like that's all it would need, replacing flippers and rebuilding flippers is a common aspect of pinball ownership and is done all the time right there at the house and usually only takes about 5 minutes once you get used to everything....and not to be too jaded, lol, but you can have brand new flipper rebuild kit in your hands by just ordering online long and well before you would even get a fruitful response from Stern.
Below is a link to just one of several sites that offers flipper rebuild kits for Stern machines. Always good to have this stuff on hand anyway.
I would recommend loosening that black hex bolt all the way such that your flipper shaft can slip out. Remove the coil stop (the square metal bracket that sits behind the flipper coil), which will allow the coil to relax back and at that point you can remove the plunger mechanism (along with the spring that is attached to it).
Now, put in your new plunger mechanism (Note that the rebuild kit will have -right- and -left- plunger mechanisms, both of which are different in there configuration, so make sure to take a picture before you remove the plunger so that you use the correct sided plunger mechanism), seat the coil appropriately and fasten back your coil stop.
Now, slide your flipper shaft back through the playfield and through the slot within the plunger mechanism and tighten the black hex bolt almost all the way, but enough that you can look on top of the playfield and adjust the flipper to its perfect location. Attach the spring that attaches from your new plunger mechanism to the flipper base, confirm where your flipper bat is on the playfield and that you approve of its positioning, and then further tighten the new black hex bolt that's on your new plunger mechanism pretty tight, but not crazy.
Take notice that on the side that -doesn't- have the problems that there is a little bit of up and down "play" of the flipper. This small gap is important to allow the flipper shaft to sit exactly perpendicular to the coil as the plunger goes in and out of the coil. If you make that flipper bat too tight to the playfield, underneath the playfield that plunger mechanism sits at an angle and does not go in and out of the coil smoothly. This amount of "play" is important. And it sounds like you have one side to use as a comparison.
Yeah, if you have that black hex bolt at the plunger mech as tight as you can physically make it and it's still slipping, there's definitely a problem in the metal components within that plunger mechanism. Again, not common, but that's the problem. An easy fix and the first time it may take 10 minutes to do, but in the future will only take 2 minutes. Replace with confidence!!
There are several nice YouTube videos on flipper rebuilds that you can check out. In your case, really just need to exchange out your plunger mechanism for a new one, not exactly a full rebuild, just a component swap out... But the videos will also give you additional confidence.
Congrats on scoring a Star Wars. It's a great game!
