mucked up Shimano HG chain repair

I just bought a set of Wipperman Connex links for my Shimano HG-59 chain. I brought the links home and took out my Crank Bros. Mini-17 tool and attempted to push the rivets out of one of the existing links on my chain so I could put on the new link, but failed miserably. I was able to push the rivet about 1mm out the other side, but couldn't get any more leverage on the chain tool to get it all the way out. I then took my rear wheel off and had to push the rivet back from the other side so everything was flush again. I just spent five minutes with the bike on a stand shifting back and forth through the cogs to make sure that everything was running smoothly again.

My question is, do the Shimano HG chains require a special chain tool, or should my Crank Bros. one have been able to do it? Also, the link I worked on appears to be flush again and everything is spinning freely and shifting well again, but should I be worried about my failed attempt at removing that pin? I mean, I wasn't able to push the pin out very far.

Get a regular chain tool. The Mini-17 is for on-the-road repairs and is not intended to replace full-size shop tools. Those HG pins take a bit of force to remove.

Your chain should be OK (hard to be certain w/o actually seeing it), but if you do install the Connex link try to do so at that same link; no point taking unnecessary chances.

Personally, I am not a fan of most of these combo tools. They have things I don't need and what I would use don't look as effective as a few single tools (3 or 4 Allen wrenches, a couple tire levers, patch kit, a Swiss Army knife with a screwdrive). For on the road chain repair, I bring along the Park Compact Chain tool. Even with this, I find the Shimano pins can be a bit of a challenge.

I believe I have that same tool, and it kind of pissed me off that it wouldn't push the pin all the way out, because it won't, flat out, no matter how much leverage you have there is a stop on the tool that keeps it from doing it. What you have to do to take the chain apart is go until the tool stops and then bend the chain away from the side the pin is sticking out of and it pops right out. It sounds like you need a real deal shop quality chain tool for what your doing though.

If it takes a lot of effort, you're obviously not using the right tools, or not using them correctly.

In this case, vise grips help to increase leverage...

The stop is there for a reason. It's to prevent you from pusing the pin all the way out, which then makes it damn near impossible to reinstall...

Good catch. .. I put a longer replacement pin in my park mini brute so it would push the pin all the way out.

Not as well; one is sacrificing utility for portability (but you knew that).

But in this case you want to push the pin all the way out.

On my Park mini chain tool, I simply unscrewed the pin just a little using a common pair of "channel lock" pliers. Now it will push the pin far enough to remove/repair/peplace a link without pushing the chain link pin all the way out.
