So tonight I fired up the new compressor and tackled a few more parts of my 1275 tear down. I stopped by Checker Auto on the way home from work and took advantage of their tool lending to borrow a 6" gear puller -- cool program, you pay for the tool up front, and they refund your money when you bring it back. Used the puller to remove the crank pulley, flywheel, and timing gears. very handy!

Questions at this point (there will be many more):

What's a woodruff key and how do I remove it (crank and cam shaft bits that stick out of the front of the block)?

Should I plan on replacing the timing gears and chain while I'm there? Not sure how to tell if they are worn.
 
I could be wrong, but I believe that's also what many people call a "key". It's usually semi-elliptical on one side and flat on the other, they come in different thicknesses. It fits into a slot on both the crank and the pulley, thus locking the two together so the pulley can't slip.

TO remove, I believe you just unbolt the crank and pull iot off. The key just slides into a slot (1/2 in the crank, 1/2 in the pulley) that is cut along the crank's axis.
 
So that little key-thingy does come out? I tried (briefly) to remove the one on the crank, but it didn't seem to want to budge. I'll have to try again tonight.
 
Use an old pair of side cutters to grip and lever.
 
Drew,

I tried to remove it when I pulled apart my 1275 engine...wouldn't come out. I'd leave it in because it might be the one you want. Really won't know until you reinstall it and degree the cam.

Then if you have to remove it...give it a try. If having trouble take it to a machine shop.
 
I usually just use a broken screwdriver as a chisel (DON'T use a real chisel!!!) and tap it under the Woodruff key to pry it up.

PS: a real chisel is hard and will scratch the heck out of your crankshaft. A screwdriver is much softer and therefore less damage.
