"If you need further instruction about the retaining clip -- just ask - I'll write more."

Here's what Don wrote on that subject in the link I posted above in Step 7:

"With a small pick, remove the clip locking the right impeller to the motor shaft. You must pry one end up, slide it sideways, lift it out, and slide the clip off the shaft so it can be removed. Be very careful -- those clips like to snap far, far away. They're worse than kids. "

As much as this might be second nature to one who's done it more than once and seen how it works, I could not describe it with better words. However, a photographer can take it a step further.
