This is probably a dumb question, but could you clarify the pictures included in your post?<BR><BR>The pictures show 5 holes in the "top cap", 2 that appear to be threaded and 3 that are not. <BR><BR>The first two pictures in your post appear to show the bolt inserted through one of the non-threaded holes in the "top cap." If your impeller is like mine, the 3 non-threaded holes in the "top cap" line-up with threaded holes in the actual impeller.<BR><BR>The last picture in your post (the one that shows the impeller loosen from the shaft) shows two bolts that appear to be threaded into the "top cap" to force the impeller off. <BR><BR>Can you clarify if the bolts where threaded into the "top cap," or through the "cap" and into the holes in the actual impeller. Your assistance would be GREATLY appreciated.
Sure. The bolts were not threaded into the top cap when they are being attached to the impeller. The threaded holes in the "TOP CAP" are only there to screw the bolts (once removed) into the topcap to exert a force and push the "top cap" off of the impeller. The three long bolts also have lock washers.
I have removed other impellers and this design is ingeniuos (in my opinion). By contrast, a Billy Goat blower impeller can be a bear to remove, and a Little Wonder impeller (once removed) will probably not fit any stock engine. Not that these other blowers aren't great machines.
