agitator was not agitating

The agitator is the tough thing to remove, I took a previous posters advice and used a rope and 2 boards to pull it up. I will describe it as many short ropes but it can be done without cutting the rope if you think a lot about it. loop the a rope under the agitator so its under 1/2, loop another rope under the other side. tie both loops so you can slide a board in each across the top of the washer. Then tie the 2 loops together on 2 sides down near the bottom of the agitator otherwise they will come out from under it when you pull. then slide the boards in the loops and lift up pulling up the agitator.That is the hard part. Remove the bolt on the coupling, and pull it off. The new one had to be lightly hammered on with a rubber mallet, then use the new bolt. the Agitator slide down and with a push down it popped on. Putting the new part on only took 15 min, removing the broken one took about 45 min. Washer is woking great now ! Saved over $100 or buying a new washer !
