Secure the bike with the rear tire off the ground.
Take the nut off the one side of the pivot bolt.
Now get a rubber mallet or deadblow, and beat that pivot bolt hard a few hits
Don't be afraid to hit it hard, because thats what it'll take to get it out.
DO NOT use a hammer and beat the threads or mushroom the end of the pivot bolt or you'll never get it out unless you cut it off.
use one hand to hold the swingarm while tapping the bolt, which will take a little pressue off the bolt making it slide out with each tap.
Before reassemble, clean the bolt and the threads.

Is it a through bolt? Does it spin on one end while turning the other? Put the nut back on and tap it with a lead hammer, see if it is just a big bolt, then drive it out the rest of the way with a dowel. Hope this helps.

SOURCE: how do i remove the pivot bolt from the swingarm
It will have a nut on one end (usually a 22mm, or 7/8" socket) and a washer. Most bikes you have to remove the rear brake pedal to allow the bolt to come out. It should come out with help from a hammer and a large punch. If it doesn't, no one has ever removed it and greased it up. I have seen them so bad you have to cut the pivot bolt out, not a fun job!
Just for some information, in a race season, I pull every nut, bolt, bearing and pivot point apart to pack some grease in. Then I lock-tite all hardware (Blue 242) This helps down the road. I do this a couple times a year.
