Quoted from Gatecrasher:
Here's what it takes to properly rebuild linear flippers from a 34 year old pinball machine. It might cost a little to do it right but it's worth it:
My guess is if you are having problems with the flipper sticking in the up position, you need to look at the coil sleeve, the plunger, the nylon bushing and the plunger stop. Another thing to look at is binding on the nylon bushing or if the bracket is cocked or bent. It sounds like something pretty-simple to me. I think I've had a problem like that once but was able to eliminate it after proper diagnosis.
I'm pretty anal about having all of my pins working 100% right down to every bulb.
If these flippers were as unreliable as they have been for you, EBD wouldn't have lasted a week on location because they got the crap played out of them back then.
I ought to know. As a kid in 1981 I fed EBD more quarters than I ever fed any other pinball machine.
This about makes me cry. Why would you put linear flippers back in. I put the older style plungers, links and paw and then go with the plastic lighter flipper. Though linear flippers work when they get hot and alittle wear boy are they sluggish. I can tell every time I am playing a game with these flippers especially alittle lower voltage like at a show. Painful....
All the collectors in the DFW area always ask me why do my classic Bally's play so well especially my 81's. I tell them outside of the full restoration its all about getting rid of the linear flipper.
I know we have debated this til the dogs come home but....painful.
