ok I checked the box again. What it says is:
"Clip Installation: Use a press-fit tool, not vise grips. After seating the clip fully in the pin groove channels, back out the side plate so that it is tightly fitted against the clip, creating a "Tension Seat" between clip and side place. Close end of the clip must face the rotational direction of the chain."
You can see in the photo, it's a normal looking clip master link. Nobody has heard of this kind of thing?
Don't quite understand the question. Sure we've all heard of it. No big deal.
If your side plate is not a presss fit, then you have the wrong instructions. Put the plate on, seat the clip and you're done. Very traditional. There will not be any "tension seat". I'd rather safety wire the clip on then monkey with this "tension seat".
If it is a press fit, then theoretically you should use a press-fit tool. However, the proper use of vice grips will work. You have to go teeny tiny bits one pin at a time so the plate doesn't bind. MAybe 15 to 20 total squeezes. Use a nut to cover the pin as it emerges and transfer the squeeze pressure to the sideplate. I have pictures and I think I posted the method in tricks and tips forum.
If that's your chain in the picture it looks fine. Main thing is if it was a press fit, you don't want to press it on so far that it contacts the inside plates of the front and rear links.
