|Help! Stuck Crankarm!!!||crosscut|

|It's winter and time to do my winter overhaul. Everything is going fine. I'm replacing cables, brake shoes, took my derailleurs off and cleaned and lubed them.
Then I got to the cranks. They are Dura-Ace splined. Been on the bike about a year and a half. Connected to an Ultegra BB, English thread. Nothing uncommon there. The drive side came off smooth. The non-drive side crank arm is STUCK! The are the self-extracting kind. It's like the splines are welded together.
Anyone else have this sort of problem? How did you solve it?

|Oh, and one more thing; if you try it with the stock self-extractor, first remove the ring and grease it well on the back side; then reintall and attempt the extraction; might help.

|I think Ammonia is used to help with a stuck seatpost in a steel frame. I think this is an aluminum to steel issue. It may work but I am not sure. I have never had this problem.
You would just use it like you would liquid wrench and let it set penetrate for a little while.
A couple of taps with a rubber mallet may help loosen it up a little as well. Not too hard though.
