I'm replacing seals under the timing cover on my 2000 accord lx 2.3L vtec manual, and I've hit one of those issues that takes a 2 or 3 hour job and makes it endless.

The front balance shaft sprocket (the sprocket above and left of the crankshaft, connected to the oil pump housing) has a 12mm bolt in the center that turns with the sprocket I can't break free for anything. I've already broken a screwdriver by placing it in the shaft hole that runs through the shaft from 3 oclock to 9 oclock, and bracing it against my alternator. It's to a point where I'm afraid something's going to break . Is this the correct way to remove the sprocket? Reversed threads maybe?? Idk, if you've done this before and it required something unorthodox please let me know.
