c drawbar clamp pin removal

TJC in MN · Mar 26, 2010

Hello,
I'm trying to lower my drawbar one hole lower. One clamp capscrew is off, the other has been broken. Now I have to try something like extracting it out. My question is, are the clamp pins on the c drawbar removable? do they pound out or in a certain way? I can move the clamp with a little force, but not the pin. Maybe if I can get drawbar off it will help me get broken bolt out, if it's possible. Any information helpfull. Thanks

Once the pin is rusted in they can be fun to get out. On the one in the picture I would weld the pin solid to keep the clamp from turning turning on the pin. That way you can heat the casting beside the pin and pound with a hammer to get it to move back and fourth some. Use plenty of your favorite magic juice after you get the pin to move some and then work it with a hammer and a big wrench until you can turn it 360 degrees. After it will turn they you can get a pry bar of some size to pry out as you turn. Once the clamp bar is off you lose the advantage to turn the pin.

On the bolt I make sure I am dead center and drill a small pilot hole square on center and then drill out to the tap drill and then clean out the old threads with a tap. Forget any type of extractors. They will only add a few days to remove the broken extractor.
One of those jobs that takes some time.

Once you get the pin out and the drawbar off. you can put an overtsized nut over the broken bolt and weld it to the bolt on the inside of the hole and then work it out easily.
