Remove the grease cup body using a 7/16" wrench.
Remove the four screws on the cover plate and the cover plate.
Grab the base of the impeller, not the vanes, with a needle nose plier, etc. Wiggle the impeller until it moves out of the housing (many times it can be wiggled out without removing the grease cup). The impeller is held to the shaft with a small bronze circlip.
Hope this helps.
