I have a problem to put apart the cap of the old clutch master cykinder, it seams that is rust weld, an i try so many things
any sugestions????

plaese! jejeje
I had the same problem with mine (1970) I just purchased a rebuild kit locally and honed the cylinder installed it and have had no problems.
The plug will thread out, it's probably just rusted. Use a good penetrating oil (3M penetrant works well) and, as the book shows, put it in a vise, and use a pipe wrench. I just finished the same job, both master and slave, and it was no fun. It took 3 hours to break the end plug loose. The end plug is about 3/4 inch deep fine thread, Just use the penetrant and go easy. You'll get it. Pictures below. Good Luck

For reference, you can get a brand-new OEM Aisin master from Specter for $160 or a new aftermarket for $70.
