Hey Vid! I have Firepower and Black Knight. I want to rebuild the flippers (all 6) but want to get away from the coil spring. Does the early WPC flipper with the tab and rebuild kit work in my machines? What would you recommend before I buy parts?

So maybe buy the entire assembly from PinballLife? Or buy rebuild kits and bushings and new style plates (where? Can't find them at pinball life)?

Couldn't find just the bases at PinballLife. Thanks!

Figured it would be cheaper to get the parts separately because I don't need the coils.

Sorry, I haven't looked further into this so forgive my ignorance. Will these bolt right in place of the old brackets? Is there any difference in the upper flippers on BK I should know about?

Vid, how do you have time to make all these detailed posts? Great stuff, Thanks!!

Most likely the switches. Finish the job and try again.

Awesome!

Is the shaft slipping in the clamp or is it possible that the bat is slipping on the shaft? Broken?

Now you may need to grind the clamp open like vid said. You probably have stretched the clamp a bit and could use that extra turn or two to clamp the new non-defective flipper.

Isn't it amazing how we end up missing things that are right under our noses? I do it all the time.

EM machines need a little lube in the pivot and rotating points of stepper units. Can't think of anywhere else I would put lube of any sort on any pin from any era.

Are we talking about doing a flipper rebuild using the newer style spring setup? Is this why you want the bracket with the capacitor mount? To use as the spring mount too?

I agree.

I would like to go this route for BK and Firepower. That makes 6 brackets and 3 rebuild kits and 6 bushings. Is there anything else I need and what pinballlife rebuild kit should i get? There are three kits that all look the same to me, but they are labeled differently.

I would check the cabinet switches and all the solder joints on those switches and the coils too. I have heard of some common flipper issue with modern sterns but cant remember specifically what it is right now. I'm sure someone else will chime in on this.

This thread might help a little.

Make sure your EOS switches are good and clean and have good pressure between the contacts when closed.

Yes, Lane Change. Hard to tell for sure, but it looks like they are adjusted closed. They should be open when the flipper is at rest and close when the the EOS switch is hit.

If all I have are $50 bills but they are crisp, could I get away with it if I use two?? Or do I need to go to the bank?

Here's one not covered in this thread. Rebuilding late Gottlieb EM flippers. The plunger and link (which is a big block of plastic with a guide "pin" sticking out of the back) is not the same as the rebuild parts I got from PBR. has the guide pin been removed for a reason, or do I have the wrong part?

Also, what method is best to remove the roll pin and also replace it. Don't want to pinch the metal tabs of the clamp together and create a bind on the plunger link. Is the orientation of the roll pin important? The slot in the pin should be forward, back, sideways? What do you think is best here?

On the gottlieb EM flipper rebuild..... Thanks vid for the info. I also posted about this to the guys in the EM hangout and this is what I got! Great info on this topic.

Got my answers and then some. Love this place!

Just not wrenching hard enough. Try a small ratchet with a 1/4 inch socket and a hex bit in it to fit the Allen head side. No extension. Use a closed end wrench on the nut side. Work both wrenches toward each other for the best leverage and also to relieve the stress you are putting on the rest of the assembly.

I think he is 113. Based on the year of his birth, 1900.

The indentations the set screws make in the shaft can get in your way if you are trying to make a small change. The set screws seem to find their way back to the original spots unless you are making a large change. The fix is either swapping the flipper bats from right to left and vice versa, or buying new ones and getting them set right the first time.
