    Hey all,

    I'm about to replace my first flipper assembly, and just wanted to make sure I have the right tool.

    I have a soldering iron, but need solder. Is there any specific solder I should be looking for?

    Also, for the wire strippers, would something like this do the trick:

    https://www.amazon.ca/Capri-Tools-CP20013-Professional-Stripper/dp/B01018D07K/ref=sr_1_1

    And finally, when soldering wires back into the coils, should I tin the wire and diode, and then stick them together with heat, or should I lay solder onto it while they're together? What's the best approach?

    Thanks

    You guys are going to have to bare with me... I've never done this before, in fact I've never soldered. But I have a friend coming over who is a pro, so I'm planning to learn and take this on myself next time. I've learned a lot in the 4 months of being in this hobby

    What are lugs? As far as I can tell from reading, I'd just strip the wires, tin them, and then solder to the 3 diode legs on the coil. And of course solder the EOS connection.

    When doing the EOS, should I wrap the wire around the circular opening and the solder, or just tin and heat against it?

    Lastly, when I get that all on, and I'm adjusting and tightening the flipper bat, do I put the Williams spacer tool on the playfield under the bat?

    Or do I do it like this:

    I just loosened up the pawl on my IJ flipper to move it down, and then when I tightened it up and tested it, the first time I hit the flipper, it went up and ended up moving higher than I had set it. Had to loosen again, adjust again, and finally it worked. Also if I loosen that pawl all the way, I can't pull the flipper off the playfield. Feels like it's stuck in the bushing.

    Any thoughts?

    Really appreciate all the help guys

    Quoted from SUPERBEE:

    Btw... what game are we talking about?

    IJ (Williams).

    I bought the full replacement assemblies shown here:

    http://www.pinballlife.com/index.php?p=product&id=172

    So really all I need to do is screw it in, solder, and line the flipper up.

    I'm guessing the wires should go in the same place if the coil part number is the same?

    Quoted from Skins:

    Kudos to you for getting in there and learning.

    Cheers!

    I guess we all start somewhere, but I definitely have an interest is learning about how all of this works.

    See the part I'm using in the post above.

    Quoted from Completist:

    As far as connecting the wires to the new coil, just confirm that the diodes are oriented the same if you are referencing the old assembly wiring (look at which side the band is on). The power goes to the banded side of the diode.
    I like to get a good mechanical connection first then add solder. Insert wire thru the hole and bend around lug. More than one wire may not fit through at same time but you can still wrap the wires around the lug. When you add solder you want to minimize any movement while the solder cools to avoid a bad joint. Tinning the wire is ok but its recommended to add some new solder to the joint as well - the flux from the rosin core solder will help you get a good joint as it cleans off any oxidation at the connection. When you are done the joint should be shiny and smooth and feel secure when you tug on the wire.
    Best part is if you don't like it just desolder and try again. Good luck!

    Here's a photo of the old assembly and the new.

    I know this is likely a moronic question, but I see things about connecting to the banded side (which I understand is the side shown here with the diodes).

    But it your putting the wire through the lug holes, does it make a connection to the entire lug, top and bottom?

    Quoted from LTG:

    Yes.
    LTG : )

    Let's go for one more stupid question!

    Do I put solder on top and bottom of lug?

    #20 6 years ago
    Quoted from LTG:

    Not stupid if you don't know and want to be sure.
    Doesn't matter top or bottom, though it will flow better from the top. Put the wire in the hole, heat the joint and flow solder on, let cool, give it a couple yanks to be sure it's tight. Then you are done.
    LTG : )

    Put it in the hole and wrap it around the lug, or just through the hole and the solder in place?

    Also, when stripping the wire, how much exposed length should I be giving myself?

    #22 6 years ago
    Quoted from LTG:

    I like to stick the wire in and bend the end over a little to help hold and make soldering easier.

    1/4 of an inch should be plenty. Once you learn, decide if you want a little more or a little less.
    LTG : )

    Llyod, you're a stud!

    Appreciate every single reply you send. This forum is very lucky to have you.

    And hey, at this rate of me learning about pins, you might be calling me in to service your machines one day!!! Hahaha one can dream right?

    Quoted from Homepin:

    ^^^ THIS ^^^
    Seriously, "if it ain't broke, don't fix it"
    I suspect you have some flipper "problem" or issue and have decided to change the flipper assembly without correctly faultfinding.
    Why not tell us what the issue is FIRST before you make a bigger problem here? That old assembly looks good enough to go into a new machine.
    Swap two wires over (accidentally and very easy to so) and you will be up for expensive board repairs - think carefully please before doing this.

    Appreciate that you're trying to save me some time and money, but I wanted to replace it all new, and get the experience.

    With the issues I'm having with the flipper on my MMR, I will troubleshoot and look to adjust parts before replacing.

    Thanks again.

    Ok, last things and I'm ready to take this on...

    Based on my photos of the old and new coil above, does it appear that all 3 wires would go right into the same position?

    And once I get it all together, and put the flipper bat in, where do I insert the flipper spacing tool? On the pf between the bat and pf?

    And for adjusting the position of the flipper with a toothpick. Any tips on keeping it in place as you tighten?

    Thanks again

    Quoted from TheLaw:

    Correct. You can see the banded sides of the diodes are facing the same direction as the original coil.

    The thing you should be more aware of is the level of tightening you will need. You're going to have to man up and really crank that thing down HARD. If you don;t it's going to become lose and you'll have to do it again.

    Like this? I cranked it to the point of resistance and you can see the bolt is bent.

    As for the spacing tool... Where does that go?

    Success!!!! (Borat voice)

    Got the new flippers in and soldered it up nicely.

    Had a lot of fun with it and now I will be tackling all of the leaf switches next.
