Hey guys, looking for some help/advise here: the '87 I'm helping my nephew rebuild has the swing arm pivot bolt stuck in it. The bolt turns easily but will not pull-out, nor will it drive-out with a brass drift and large hammer. So, I'm assuming that one of the inner bearing races has froze to the bolt. Anyone got a good method for getting the bolt out to remove the swing arm?
Like heat it with a torch? Cut the bolt at the arm-frame gap? Any secret "un-stick" methods?
Thanks for any advise anyone can offer.

Use a saw and cut it between the frame and swingarm. Its a pain in the a** but thats the only way.

soak it with penetrating lube for a couple days. keep applying and tap with a hammer every time you apply to help penetrate and break the rust bond. then heat with mapp gas after the couple days of lubing while hitting with a hammer. if this doesnt work then you will have to cut the bolt.

I tried it using penetrating oil, it didn't work. I spread the frame slightly and cut the bolt on both sides, removed swingarm and cut the bushing on both sides of the motor mount.

Thanks guys! I kind of figured that was where I was going to end up, but I wanted to check and see if anyone had a special method that worked better! Once I get it out, I'll let you know which method I had to use...
