Removal of the woodruff key

[cubfan1968]

Ok, I'm gonna ask the question as dumb as it might sound. I'm installing a MZ-B Ignition in my 125B. The directions say to remove the woodruff key. I take its the small piece thats on the taper of the crank shaft. How do you remove it? It looks to be machined on. I look at the new flywheel and its got a slot just like the old one, why don't I need this key to stay? Any help would be appreciated.

Rod, when I installed the MZ ign. on my Piner I had to remove the key. The MZ flywheel for the KTM motor did not have the groove for the key. It relied on the interference (sp?) fit between the flywheel and the crank. It could be that the groove on the new flywheel would not allow the timing to be set correctly on your motor as it would not line up as the old flywheel did. Just my thoughts... Dennis D

Ok, I understand the timing issue. That makes sense. How does the key come off. Its probably real easy, but I'd rather ask a question than botch up something. Thanks

Rod,
   The woodruff key is basicly a half moon shaped key that fits in a machined slot on the crank and is used for flywheel alignment. Since you don't need it take a small chisel or a good screwdriver that has a strong plastic handle and place it against the end of the key where it meets the crank.   Very lightly tap against the key and it should ride right up and out of the slot. Just a gentle tap should do it. The key is held in place by being a snug fit into the machined slot, it is not part of the crank.
Hope this helps.

Thank you very much Paul. Worked just like you said it would. I read the instructions, checked the owners manuel and parts list but before I hit it I wanted to ask the question. Waited way to long to own one of these things. Again,thank you very much.

Sorry Rod, Didn't read your post close enough. A pair of side cutters, some call them wire cutters, will also work on the woodruf keys. Dennis D

Thanks for the reply, Dennis. Thats what makes this web site great, marginal wrenchs like myself can get help before a dumb mistake is made. Thanks to all.
