Thanks for the tips. The mineral spirits has worked well along with some compressed air.
I'm not going to take the hammers out, but I would like to take out the bolt group and top lever. Mine is different than what is described in the steps.
It looks like this:

The top lever has the duck bill spring.
I was thinking as the bolt group does not appear to be under any tension, I should just have to undo the screws and the pieces will come out. Then I can clamp the spring and get that out.
