The woodruff key just doesn't want to budge, I have tried the chisel trick, nothing, can't get a good grip with pliers either, any other things I can do?

Re: Woodruff key-Can't get it off!

i feel your frustration, i just did my waterpumps and one of those buggers just didnt want to move, i found that a dull chisel worked the best, the one that i couldnt get, i ended up carefully drilling it in the center then rapping it with a punch-this did the trick-.

I would use heat last, a thin dulled chiesel works as does carefully drilling on it, a good sharp chisel just slices the edges off and makes it harder.<br /> not that I am against heat mind you but in the hands of the untrained you may do more damage than good.<br /> once you get the key headed down it will roll out the bottom.

Got it off finally with rodbolts hint, but I had to really slam on it with the hammer, not my best moment of mechanical time but it was the only way- I also had some PB Blaster that was in there for about an hour so maybe that had somehthing to do with it, because I tried the chisel and hammer trick already and it didn't budge-

Just didn't get frustrated enough the first time. You can really hit it then.

Hi folks there is a sure fire way of removing seized woodruff keys or even straight keys for that matter.<br />just get a medium sized pair of electrical side cutters and grip the frozen key as close to the shaft as possible and using the the cutters hinge as a fulcrum push down the key will pop out and all you have to do is deburr 2 little indents made by the cutter jaws<br /><br />Hope this is useful Pinno

pinno, a good trick but not on the V yamahas water pump key.<br /> best thing is a dull chisel and drive the key down and it will roll out. its a very tight fit.
