Shimano’s service instructions for the Nexus 7-speed internal-gear hub assume that you will replace the entire axle unit. Taking disassembly past the point where instructions are available is all too easy. You might also want to cannibalize parts to assemble one axle unit that works from two or more which do not. Reader Keith Lang has provided instructions in two PDF files. You may go to John’s introduction with links to those files..
