How do I remove that darn Woodruff key?

I’m in the process of taking the cam towers / heads off my ‘79 SC to get them rebuilt and the two Woodruff keys have me stumped. From what I’ve read the Woodruff keys need to come out for the cam seal to be taken out so I can get the chain housing off to pull the camshaft.
How on earth are those keys supposed to come out? I tried prying, tapping, channel lock pliers, those darn keys did not move one bit. Any help is greatly appreciated. Thx Bernd

I had some trouble with them at first too. Once you figure it out they are easier to take out. I found a post from John walker somewhere which helped me. I believe a hammer and small flat blade screwdriver. They are rounded in the back. So if you tap the bottom of the key it will start to rotate out and you will be able to get it out easier from there.

Exactly.

The key is surprisingly soft, and the screw driver blade may actually mar the key some. Easy to fix when you get it out with a file or a whetstone.

Biggest worry extracting or reinserting these is having it fall out. Rags where the chains enter the case, and more generally to avoid hunting around on bench or floor.

Channel locks do the job squeezing them back in when you are finishing up your work - you can get them flush and level, though just a hair lower on the front works to help get the adjustment collar started over the key.
The cam is hard enough that the channel locks won't mar the surface, which doesn't have anything rotating on it anyway.

darn key

Agree with Catorce and if you lay the key on a flat file and remove a little material installation is easier as well.Fred

Tapping and prying with a small flat blade screwdriver usually works.
If that doesn't work after trying repeatedly then a large pair of wire cutters also called "Dikes" will do it.
Grab on to it with the dikes and pry it out by carefully prying against the end of the camshaft. You can put a folded up rag between the dikes and cam to keep from leaving any marks while prying.

They can get a little chewed up after removing them many times and new ones are really cheap.

honestly... I just rocked it back and forth until it moved more freely and then just rocked it all the way back till it stuck out in the front and then just rolled it out.

Alright, they finally came out after some not so gentle tapping...I’m glad Pelican sells replacements, the old ones are way beyond re-using...

On a more nasty note, here’s what happens when you screw up up the ‘lefty loosey’ while taking the cam nut off...guess I don’t know my own strength...

Is that the driver's side cam? If so, I have one from my '79 SC when I replaced them with 964 cams...

Yep, drivers side. Too bad I already ordered a replacement from dcauto. You wouldn’t happen to have a good passenger side one for a 79 sc? My passenger side cam has a bit more pitting than I like it to have..
