Hello folks. I was wondering has anyone disassembled a Yankee screwdriver? I have 3 I bought at the flea market and they are badly in need of cleaning and lubing. I'm working on a 133H. The others are a 30A and a 131A. I have the 133H mostly disassembled, but the spindle washer has me stumped. How the blazes do you remove it and get it back in? Or was it made so only the manufacture could remove it. Any tricks that anyone has up their sleeve will greatly appreciated.
