400ex pivot bolt

Sorry. I meant to say "impact hammer". Go rent one and it will drive the bolt out.

After much frustration, agrevation, cussing and destroying things, I got it out. Beating on the bolt was useless, I had to cut it. What I did was cut the bolt on the right side between the motor and swing arm. What I did was first a little bit at a time and turn the bolt with a pair of pliers on the nut side and cut some more. Eventually cut it all the way off. Then I did the same thing again cutting out about 3/4" from the bolt. Then I slid the motor over and cut the bolt on the left side of the motor the same way. To cut it, I used a straight grinder with a 3" cut off wheel. Only damage was to the swinger, burnt the rubber pads a little bit.
With the motor out, I was then able to knock the left side of the bolt in to free up the swing arm. The right side of the bolt was another story. To get that out of the swinger I had to beat it outwards. When it finally came out I found out why it wouldn't move any more.
I don't know if the crack there was from me pounding on it or if that was part of the reason it was stuck. In any case it is out and I am ready to move on.
Side note, the sleeves are what I think was keeping it from moving, everything else seemed fine. Putting it back together, never seez will be my best friend at this step.

The anti-seize is a great thing to do, but you should mix it with waterproof grease. And if you haven't put the swing arm completely on yet, do this: Put anti-seize/grease on the bolt and run it into the swing arm. Then pull it out, put anti-seize/grease on it again and run it through the other side. Then assemble. The reason is because the anti-sieze/grease (or anything you put on a bolt in a situation like this) gets wiped off as you insert the bolt. So, the far end of the hole remains dry. It's very difficult to get anything to the center though. The best way would be to use a dowel of a somewhat smaller diameter and coat it with NS and run it through. Just my 2 cents.
