ordered new pumps on boxing day and just got around to setting up tank one must be old style 6105 and 1 new but both had same impeller shaft setup so do i just remove impeller from shaft and place in new half shaft .
also would i use end rubber pieces on the half shaft pics would be good as tunze instructions online are terible
