Quoted from spinal:vid1900,
Q1: Do you "use Loctite 245 when reattaching screws to the Flipper Stop Assembly, the Solenoid Bracket, and the Flipper Bushing" (as recommended in my MM manual 2-15).
Q2: Notice Marco only has Locktite 242 - is this the same stuff?
Q3: In MM manual 2-15, 6-32 Hex nuts for flipper bushings don't look like backing lock nuts. What are best nuts to use here?
(Thanks)
245 is somewhat stronger than 242. Both are rated for removal with normal hand tools, supposedly, so you should be able to get away with using 242. I'd check the parts after a week or so to make sure it's really holding, but I doubt that 242 would fail you in this, if used properly.
NOTE: Wipe any remnants of old locktite off the screw before applying new stuff.
