I am attempting to overhaul my 1982 Trek 614's bottom bracket. I have gotten the crank arms and the lockring off. I bought a Park HCW-11 tool for removing the bottom bracket but it appears I need a different tool. There are no slots to fit the tool into. I have attached pictures - what tool will work to remove this bottom bracket? Do I need to remove the drive-side as well if Im only overhauling it?
