Ditto. Shouldn't be that difficult. For most pumps, I just grab the impeller either side of the shaft with needle nose pliers, wiggle the thing while pulling. Most just come right out. When replacing, put a little lube on the vanes and shove it in.
The vanes will assume the proper bend after a few rotations. Dennis C.
