...for your consideration as you proceed, now that the bolt is off. I have grown weary over the many years I've been doing this stuff, with freeing up old stuck crank fixing bolts. The worst ones are the ones lie Zeus, where the 16 mm bolt head gives you precious little room even for a thin wall socket. So I very often replace them with a couple of these socket head crank bolts. They show up a lot over at the co-op as miscellaneous leftover parts, but you can also buy them new, online, if you are a big spender.
Anyway, it's harder to screw up the bolt heads using an Allen head wrench socket on your ratchet. As a bonus, you no longer need those caps that sometimes get frozen in the crank sockets.
