If there is a better forum for repair ideas and tips, could someone let me know?  I'm down to the last few minor problems on my pin, and one keeps coming back.  My right flipper keeps coming loose.  There are 2 allen set screws holding it in place, and no matter how tight i make them, it loosens right up, during the first play.  Should I try some lock-tite, or do you think something is worn out?The machine is a Gottlieb Big Hurt.

"" is a side project here. it's still fairly new so it's not 100% complete...but may have what you are looking for.

I'd loosen them and pull the flippers out.  Take a look.  I suspect you've got wear on the shaft from where a loose flipper was dragging back and forth across the bolt.  Or the bolt is worn and you may be getting really tight but it's not actually putting much pressure.

So, three options.  I've done all three at various times. 

1 - buy replacement flipper bats and shafts.  (been awhile since I've owned a Gottlieb System3, I think what you're looking for is a "shoe and shaft")
2 - swap your left and right flippers so that the wear on your right one doesn't line up with the bolts on the left assembly. 
3 - replace the allen bolt with something a little bit longer and torque that sumbitch down.
