Agitator-How do you get it off?

(Roper is actually made by Whirlpool) This is simpler than it sounds, just takes time and a few steps. Do you have a fabric softener dispenser that resides on top of the agitator? This dispenser simply snaps onto the top of the agitator. Some styles use a decorative cap. To remove the dispenser, simply grab it and firmly pull up. There is a cap that covers the bolt or nut that holds the agitator in place. To remove the agitator cap, insert a small flat-head screw driver into the seam between the agitator cap and the upper agitator (the part that moves). Use a twisting or prying action to pop the cap off of the agitator. Sometimes there is a little slot where you can insert the screwdriver. Look for it first. There maybe an internal debris cap under this: Inside the agitator you will see a cap with a raised handle. Simply reach into the agitator and twist the cap while pulling up. This will remove the cap and its o-ring. Removing the agitator: When looking into the agitator assembly, you will notice a single nut in the center of the agitator. Use a socket kit or nut driver to remove this bolt or nut from the agitator stud. Don't use plyers, it'll just mess up the nut. With the bolt removed you should be able to remove the agitator by simply pulling up. Twist back and forth CW & CCW when lifting. Some are a 2 piece design, so pulling up will actually remove either the whole agitator assembly or only half of it. If whole assy comes up and you may need to seperate the two for your new parts. Place the Lower Agitator on the floor and stand on the flat lip. Then Pull up to separate the Upper Agitator (mover) from the Lower Agitator. As far as your parts go I'm not sure where they go without seeing it myself. There is a spline or ratch assembly which causes the agitator to move back and forth. They are usually made of plastic and get worn or break. This might be what you are replacing. It's not clear as to what parts they gave you. Good Luck
