Bottom bracket/crank removal?

Hi! I am restoring a c.1970 Legnano which has sat in a barn for thirty years. Before I gave it to my son, I built the bike myself, but that was 35 years ago. Now I am trying to relearn all the stuff I forgot. The bike has a Sugino crank and bottom bracket, which I believe are pretty faithful copies of Campy parts of the era. I have removed the dust caps and bolts. I have a Sugino crank removal tool, which screws into the dust cap housing of each crank. Then there's a narrow threaded nut inside this tool, which I believe should be tightened until it pushes the crank off the crankshaft. Am I right or wrong? The shafts don't budge, and I may be missing something vital (like information or a part of the tool). Once the cranks are off I have the Sugino bottom bracket tool, so I can go in and repack or replace the bearings.

Assuming it's the right tool and there's no washer left inside the crankarm, it should take some considerable force to actually start the arm off the spindles. Just make sure the extractor is tightened down fully.
