Hi Geoff, its a good thing you couldn't get the Agitamer under that red bakelite agitator, it would have broken it into at least three pieces in no time flat. Filling the tub with very hot water might do the trick to loosen the agitator, but you will need long heat proof rubber gloves to try and pull it out. Hot water might not work either, I suspect the only way you are going to be able to get it out is to break it and replace the agitator. A later Maytag agitator will fit, but it wont have the float assembly
.
Is there a specific reason why you need to get the agitator off? Actually if you need to you can pull the tub and agitator out as a unit if you remove some parts from below the outer tub.
