    I am replacing a timing chain and small sprocket on a 1984 R100 with about 125,000 miles of excellent care on the clock. The chain is slightly loose and the upper sprocket shows some wear - so - replace it before it causes a problem. The bearing came off easily with a puller. The sprocket was a real bear to get loose. Took a lot of pressure for it to give up its grip on the crankshaft. The only other one I have done I just gave the woodriff key a bit of pressure, a tap with a tiny little hammer, and it came out. This key will not move. I even held a flat punch against the end of it and gave a bit of a tap, nothing. The key sits low in the front and just slighly higher in the back. It will not budge. I am looking for some ideas on how to remove it. Considering a new woodriff key is $1.40 it is in the budget to replace(!!!). Thoughts

    If the key is fine,just leave it in place. I've never heard of those keys shearing off so I'd just reuse it.

    You can leave it in place, I would.

    If I have to get one out, beat down on the back of the key to raise the front. Once it moves a little it will move more. Using a punch or something to beat the rear in further. Eventually you have enough of the front exposed to drive it in and out.
