You have to give it no more to loosen it, let it be stuck and nothing more, handle WD40 and let it rest and hit the hammer on the side by turning the pulley a little every time, then another little of WD-40, and so, it has to leave it is not secured in any other way that with a key, if you do not have wd40 you Loose anything.
