    What's the trick to installing this $#@! Shimano Quick Link??

    I can't believe the problems I'm having installing a new Shimano UG 7 spd chain. It comes with this non-standard "quick link"; two-piece master link (see pic). It consists of a plate with two pins, and a connecting plate that secures this to the chain. The connecting plate has an enlarged opening on one end. This goes on to one of the pins, the plate is then pushed up, and the other end is pressed on to the second pin. I have tried following the instructions and a prior thread on this, and still can't get it on. I have tried bending the quick link outward with as much force as I can; and I even tried using pliars to squeeze the connecting plate on. It ain't working. I tried pushing the connecting plate as far on to the first pin as possible, tried bending the links to get it on, tried stretching the links to get it on... it ain't getting on. So much for "quick" link.

    Do I even need this $#@ thing? Especially when the instructions say once it's on, it should not be installed a second time! I have a couple of extra links. Is it just as good, if not better, for me to simply install another link, instead of this "special" so-called quick link?

    Never seen that design on a shimano chain before. Interesting.

    As far as your installation goes, you need to turn the faceplate 180 degrees and slide it over before you try to engage the second pin.

    Read the instructions that came with the chain. It gives you precise instructions on how that link is installed.

    Well, I guess I just figured out the problem (I mean besides the problem of this being a REALLY craptastic design). Only because I took the link off in order to photograph it for this thread.... looking at it more closely, I realized the plate with the two pins was slightly bent outward, in the centre (maybe by my trying to get it on the chain, or maybe it came that way). This would not make it as easy to fit the connecting plate. So I bent it the other way with pliers, so the pins are slightly toward each other. This eventually helped me get it on, but even then, only with pliers; not my fingers. And not perfectly, as the pin that fits into the enlarged hole is not 100% all the way in, as much as the other pins. The chain could conceivably break at this point, if this is not the normal way its supposed to fit. But my prodding with the pliers is not getting it inserted any better; and risks making things worse. So, I'm going to try going up a steep hill and see if the chain snaps or stays in place. What's the number to that 700 Club again?

    You need to turn two adjacent links 90-degrees. This gives you the room to slide the clip over the 1st pin, then straighten it out to pop over the 2nd pin. Bending the opposite plate so the tips of the two pins are closer is the key. Then release and the pins move apart and nothing is lined up with the big hole.

    Operator is back, how charming.

    To OP: The Quick link is designed to quickly drive you mad, at least it looks like it is..

    The first Sram powerlink used the same kind of rear plate/front plate as the Shimano. You have to flex the rear plate (the one with the pins) together to get the front plate over the pins. The Sram version was just as craptastic as this one is. The new Sram Powerlink is a much better design and easier to use. Shimano will probably be copying that one is a few years

Bending the opposite plate so the tips of the two pins are closer is the key. Then release and the pins move apart and nothing is lined up with the big hole.
    I tried bending the adjacent links yesterday to no avail, as the pin would not align well with the large hole in the front plate. I have and had read the instructions, but I could not get the front plate to snap on as shown in figure 5. As I described in my post yesterday, and as DannoXYZ and Cyccommute describe today, the rear plate had to be bent so that the pins are closer together, to even hope getting the front plate on.

    So anyway, I'm still having problems with the chain. Having ridden the bike yesterday, I feel a skip each revolution. I'm assuming it may be that the pin is not fully engaged in the large hole, if it isn't something else. One question I asked remains: can I do away with this damn quick link and just use a standard extra link to join the chain, particularly since the instructions say the quick link can't be used more than once anyway? Or is there some reason why you would need the quick link to join the chain?

    Super. Now let's see if we can figure out why the chain is giving me problems (skipping), after I already figured out how to install it yesterday. Here's some more pix to look at. Note how the plates of the quick link are not bent outward, as with the other links:

    You shouldn't have bent those two pins together with the pliers. Just put the chain together, slide one end of the "connector" over one pin, flex the chain until you can get it over the other pin, slide it on, relax the tension, done.

    It sounds so easy when you say it.... but no seriously, the chain wasn't having none of that. It might have been flexing it in the wrong direction (outward instead of inward) that prevented the connector from fitting over the pins, but at any rate, it would not fit; with hand pressure or pliers, until I took it off and bent the pin plate inward with pliers.

    Problem is, even after fitting the link, the chain was skipping, as I mentioned. I figured out the problem with that, as well. The connector plate was squeezed too tight on one pin (no matter which way round the rear plate was installed). This might be because the rear plate was bent, or it might be because this is a shtty master link design, or quality control whereby tolerances are not exact (and they have to be very much so, here). Anyway, the end result of this, is that the connector plate wasn't flexing as freely on one end. This caused the link to remain stiff, no matter how much you flex it side to side. After wasting two straight days of working on this one link, I decided enough is enough, and I stopped using it, and joined the chain with a regular link.

    One trusts that you used new pins? Re-using peened pins is a recipe for disaster.

    Yeah, I used the links that came with the new chain to rejoin it. I tested it by grinding hard with the pedals to see if the chain would break, and it did not. But I have other problems... I had hoped the new chain would resolve a problem I was having with the chain skipping over the teeth, mostly in the highest gear (smallest cog in rear). Not only did it not, but its worse than the chain I had prior, which rarely did this. (Yeah, I know I might have to replace the cassette, or at least one cog on the freewheel, but its obvious to me that the chain itself is playing a role here).

    Worse still, I used one link of this new chain to repair a chain on another bike (a 7 spd Minelli), which had broken due to a loose pin on one link. This newly repaired chain tested okay as far as it not breaking, after putting a load on the pedals and trying to snap it. But now it skips teeth as well (though not nearly as much as on the bike with the new chain), whereas it did not skip teeth before I repaired it with just one link from the new chain. I don't know what it is, but it may be this model of Shimano chain is incompatible with a lot of bikes. I might understand with the Minelli, as it has a Hyperglide or Hyperdrive chainring; and the new chain is a Uniglide model. But I read they were supposed to be compatible. And the other bike is an older 6 spd, so not Hyperglide.

    Uh.

    That's not what he's asking. You need the specific shimano replacement pin to rejoin links. You cannot ride a chain that has been repinned with a used pin. No matter how much you've "tested it". It WILL break at an inopportune time and you WILL die.

    The easy way to flex the tips of the pins together is to use leverage. Rather than push near the link, move your hands apart about 6-8". Hold the chain straight with the pins facing up and bend it together. You can actually apply enough leverage to bend the links together permanently so they're almost touching.

    I'm not the one who doesn't now how to read instructions. You got quite the nerve to insult me in this fashion on this forum. YOU are the one asking for help, not me. Should we expect this from every awesome thread you post?
