newcan1, I believe that the element sets simply unscrew (carefully, use a pair of pliers, newcan1).
As far as the oil: impregnate a clean, soft tissue with some lighter fluid and carefully use that to moisten the blades, then wipe off with dry, clean tissue. You will have to continually move the aperture blades (this is where the oil hides) and the shutter blades. (You might even do THIS: fire at BULB, insert a finger or other rather soft object in the hole and then 'close' the shutter. Obviously, the shutter blades will not close completely and you will see what oil lurks when the shutter blades are partially closed. Be careful and this should not damage anything.
Actually this whole cleaning might be better accomplished by squirting the lighter fluid directly into the whole lens assembly (with all glass elements removed, first) if there is a lot of oil, in order to drain all the grime. I would have to see it to advise you further but be certain to make sure ALL is completely dry before screwing on the element sets. What I do is this: after all the grime is drained and the assembly is clean, I put the mechanism in my oven. The pilot light keeps the temp at about 110 F so it dries completely overnight. But, just to make certain, every few hours work the aperture and shutter blades to uncover hidden lighter fluid so it will dry quicker. Don't force anything. - David Lyga
