Hi ESFMs,
I'm in the process of restoring an old frame. And finally getting around to disassembling it.
All was going smooth until I got to removing the rear suspension coil. I managed to remove one pivot pin/bolt (what do you call that piece?) But then that second one.... Well, is enough for me to start a thread on endless sphere for help.
I was able to remove the bolt itself but the pin side that anchors the coil to the frame just refuses to back out. It spins freely, do I know it isn't rusted or fused in any way.
I've tried threading the bolt in by a few threads and hammering it with a mallet,
I've tried lubing it AND degreasing it, then hammering it again,
I've tried letting it sit in lube/degreaser over night, then more hammering,
And just last night out of sheer desperation, I Dremeled off the head of the bolt (on the pin side) to hopefully get it to back out the other way. Hammered it using a centre punch.
I also tried to use the heat and ice method but I don't quite know how to do it correctly. I was using a hot air gun to hear the surrounding metal and an ice pack on the bolt/pin head side.
Oh, I also tried drilling into it but I think my drill bits are too weak to cut into it. It's a steel bolt.
I've exhausted everything I can think of. Have any of you had this issue before? What haven't I tried yet?
