Quoted from Frax:
I will have to see if I have pics of the teardown still, I'm pretty sure I do, but yes, bascially you will HAVE to remove the Beta Ramp and the Borg Ship to even get to the alpha ramp. If you need to REMOVE the alpha ramp, you may have to take off the left wireform as well.
Start with the right wireform and loop. Mine were ziptied together. One screw on long support on left, Screw+nut on the middle of the wireform where it crosses over, screw/posts attaching on the right side. Take pictures of those post+screw+washer stacks because you WILL NOT remember how the hell they fit together and can make annoying problems if you don't put them back together just right..
After that, remove the right wireform, it's two wood screws then it will slide out of the bracket up by the flashlamp on the top right. Remove the two small screws from the steel flap at bottom of Beta ramp. You may have to remove the flash lamp dome to get to the other two screws securing beta ramp if I remember right.
Remove three screws from top of Borg Ship. Lift plastic ship off the U-trough. There are two small screws securing part of the left ramp assembly to the borg ship, with washers. Those have to come off to remove the U-trough. U-Trough is held to backboard with I think 3 machine screws? I usually just hung the borg ship by it's cable over the backboard to get it out of the way. Same with the Beta ramp....just make sure you are VERY careful if you have to fully raise the playfield at all, lol. Don't want to shatter the ramp with the backboard.
Anyways, this is where my memory starts to get REAL foggy... left wireform from the alpha ramp is also held down by two wood screws. If you have long magnetic screw starters or magnetic screwdrivers with a very long reach, it will save you a LOT of trouble. After that, I can't even remember what it looks like under there. I did all this stuff at once....cliffy sleeves, cleaning, waxing, full plastics set, LED GI/Flashers....
I'll see what I can find in pictures.
