anyone use a cutting torch to remove old spring hangers?

Discussion in '1973-1991 K5 Blazer | Truck | Suburban' started by **DONOTDELETE**, Sep 30, 2001.

    on the last shackle flip i did i used a combo of angle grinder and drilling. drilling being by far the slowest method. the grinder is ok but hard to get into some spots. can i use a cutting torch and burn out the rivets?

    Just blow off the rivets heads with the torch then drive out the rest with a punch. I have done it this way many times and never had a problem.

    I looooove using the torch. You have to be careful not to heat up the frame alot so you won't lose strength though. Ever try an air chisel? That does a nice job too. Just make sure to drop the tank when you're playing with the torch.

    I've tried it a few ways. I think the best way I found was to use a air hammer with a chisel bit to sheer the head off, then used the same hammer with a punch bit to pop the rest of the rivet out of the frame. Not only was it relitvly fast, and made a ton of noise, it was fun to. The back half of that rivet reelly flies out when you punch it threw the frame.[​IMG]

    I second the chisel method. I did it last weekend on mine. It doesn't take very long and keeps from changing the temper of the frame. I then used a #1 unibit to open up the holes, worked like a charm!.

    I've done it a couple of times with the "blue wrench". No problem, just do as stated above. Blow the heads off of the rivets and then knock them out with a punch. Much quicker and quieter than an air chisel.

    Yes, done the flip on two different trucks and used the "hot wrench" both times. works like a charm, fast and easy. I used the air chisel to punch out what the torch didn't get. And yes, it's LOUD!
