How are the impeller & pulley affixed to the water pump shaft? Are they pressed on? How best to separate them from the shaft? Thanks!

I press the shaft off the pulley and through the pump; then press the impeller off the shaft. Click on the link below for my web site for an article on rebuilding these pumps.
