I have been told by Maytag, and found it to be true, line up the tub top to the top panel of the washer before tightening the spanner nut on the spin basket. When I'm lining up the tub top, after making sure that the gasket, clamp(lube the bolts), tub top and top edge ot the outer tub are clean, I spray 409, Windex or something wet to allow the tub top to slide through the gasket and not make the gasket twist out of possition. Just leave the clamp slightly loose, lower the top panel, center the tub with the opening on the top, place the palm of your hands on the opening of the top panel, your fingers on the inside edge of the tub top and slowly pull the tub top until it is about 1/4" below the top panel. Then tighten the tub clamp, after making sure again that the gasket didn't twist, alternating back and forth on tightening the clamp screws. Then line up the spin basket and tub top by using your fingers to make sure the spacing is the same all the way around the top of the spin basket and under side of the tub top. Then tighten the spanner nut. I used to tighten the nut and then try to line up the tub top so that it wouldn't scrape, but doing the top first works better. When Maytag went to the plastic tub top, it may have save 15 min. of time on a job that involved removing the spin basket. Glen.
