There's a rod holding the grates in that we tried pounding out with a nail, but it wouldn't budge. Maybe I just needed to hit it harder, but I didn't want to break something....

Here's the impeller....couldn't figure out how to loosen the main nut holding the impeller on.... didn't know which way it's threaded, and was afreaid of breaking off a bolt....

Tried deburring the edge of the impeller...difficult to do while it's still on the motor...
