Galion 118 B Rear Wheel Removal?

I've got an old 118 B Galion that needs a rear wheel brake cylinder serviced.

Then you have to attach a "Knocker" by threading it on the end of the tapered axle. Once that's done you have to hit the "knocker" with a sledge hammer until the axle moves out of the near wheel that needs servicing then let the opposite side wheels down and jack up the near side wheels...
