Hey all,

Maybe I’m in the right place now...

I’m having an issue on my JJP POTC - specifically the upper play-field (Black Pearl) right flipper. It’s not flipping as high as the left. Maybe half as much.

I tried loosening the nut, allowing the flipper to rest and then retighten. To no avail, the flipper flips just as high as before. I have essentially accomplished nothing or very little.

Here’s the million dollar dilemma, this upper play-field has a metal bracket that the flippers rest on so I can’t possibly position it lower or really mess up the alignment.

I did read where after loosening this nut and having the ability to move the flipper freely it will expose another screw or something. I have not tried anything regarding this second revealed screw. I thought it said to hold that second screw in place with a hex or whatever while tightening the nut back.

Maybe that’s the missing piece to the puzzle?

There’s no way this is anywhere near as complicated as I’m making it out to be.

But I’m not having any success so far.

Quoted from jfesler:

Check the JJPOTC thread. Pretty sure the right flipper in the Pearl is supposed to only half flip, in order to be able to hit the canon. There is a doc maintained in that thread for issues on that game.

Nope. They are supposed to flip evenly.

I ordered one of those flipper adjustment tools from Planetary (and because Marco was out) not so much because I feel like it’s necessary, but rather just because I think it’s cool.

It’s pretty funny though. The tool is $1 and shipping was over $7...

Oh well

#2321 1 year ago

Question guys..

My main left and right flippers on my JJP POTC:

The right flipper is absolutely "perfect." Like, it's hard to put into words, but the resistance and the spring back is I think everything and more that you would want in a flipper.

The left flipper is not. Yea, it's tight. Yea, it doesn't matter because it's not slipping between games and all this. I get all that...BUT I still want to know "why" it's not as amazing as the right flipper...

I can't really figure it out. I don't know if it's the spring. I don't know if it's the way that flipper is sitting in the flipper bushing or what.

It's just interesting...to me.

The coil rod (that's what I'm calling it. The thing that feeds into the coil) is coming up slower on one flipper than the other. They both pretty much have the same clearance so it's not binding, but it kinda bothers me.

Has anyone seen this happen before?

Quoted from chuckwurt:

Yep. Something is causing it to bind. Dirty coil sleeve, mushroomed plunger (coil rod), flipper bat not gapped properly and is too tight to the flipper bushing. Could be any of those. Or something else. Haha

This video better highlights what I'm trying to explain.

The right flipper - perfect
The left flipper - not perfect

I'ts not necessarily as drastic as I thought it was initially and it might be the OCD in me, but I appreciate any expert advise all the same...


#2333 1 year ago

Thanks guys!

I’ll keep working on it!

#2334 1 year ago

I will add that it's NOT mushrooming. I mean, I'm 99.9% sure it isn't. It's brand new!

#2336 1 year ago

Yea and in fairness I actually rebuilt this flipper myself so I 100% blame myself for it not being correct.

First pin, first flipper rebuild...

I'm trying to get there!

#2338 1 year ago

I’m definitely not arguing because I don’t know enough to know what I would be arguing about...

The flippers “seem” to have the same clearance, but it definitely feels like it’s binding.

My first step was to basically remove the flipper bat entirely and see if the binding continues. If it does not, then I guess the flipper WAS binding..

#2340 1 year ago
Quoted from chuckwurt:

If that’s not it, the way the could stop is positioned it could be pulling the coil ever so slightly to one side causing the binding too.

Yea. Thanks so much man.

I'm definitely trying to address this tonight when I get a good opportunity and I'll report back.

#2341 1 year ago

For the record,

Here's a pic comparing the flipper on the left and the right.

I'll try to not flood this thread. I find pinsiders aren't a fan of this, but working on it now and removing the flipper bat.

My game is PLAYABLE once I get this sorted! =)

I"m so FLIPPIN' happy!!!

I honestly for the life of me can't tell you "exactly" what it was.

I loosened the flipper pawl and immediately noticed it wasn't binding at all. So no need to take out the flipper bat entirely. I simply I guess realigned the flipper, tightened back down, and viola!!

It's like flipper porn!!


#2344 1 year ago


I guess it’s just really that temperamental.

I feel like I have gone full circle at this point so I feel pretty good the next time this happens - which hopefully isn’t for a long time.
