Straightening a cotter pin to prepare it for removal is not that hard but it can be frustrating if it is bent all the way over.
The pictures shows after I straightened with the tool.
I used a tack removal tool to wedge under the pin, then twist it to unfolded the pin very quick and easily.
I use this tool I found at a garage sale for removing cotter pins.
Neat cotter pin tool!
What I usually do is - straighten the ends of the pin as best I can with needle nose pliers, then insert one tip of the needle nose pliers into the head of the pin, close the pliers, then hammer on the pliers to pull the pin out.
I put a wrench on the nut and back it off shearing the pin then use a small drift to remove the rest, unless of course that you are trying to save the pin. :-). KGB
I do what Keith does, on the old rusty stuff, but not the new ones. Dave
Cool tools, but the simple way to get cotter pins out is to just grab the loop end deep in a pair of dykes and pry it right out, without even touching the bent ends. An old mechanic showed me that years ago.
I've posted this before I'm sure but I picked this tool up at a garage sale many moons ago. Seems to work well as long as you have the room. Jim
Wow! I have NEVER seen that before. That's one of those oddballs that you might pick up and have no idea what it does.
Neat tool, I'll have to keep an eye out for one!
