This was super simple. It took me longer to write these instructions than to do the repair.
1. Remove fabric softener dispenser, by sliding the teal lock ring upwards and then lifting the dispenser up and away.
2. Remove the cap from the agitator ratchet assembly by using a flat head screwdriver in the provided slot. You may have to rotate the agitator to find the slot on its top edge. Pry the top off like you would the lid of a paint can.
3. Look down inside the assembly and see the bolt. Remove the bolt, and its rubber washer. My model required a 7/16" socket to do this. You will also need a socket extender. Hold the lower agitator to prevent it rotating as you loosen.
4. Lift the agitator ratchet assembly away. Notice the two plastic tabs adjacent to the bolt head. You will need to line the ratchet assembly up with these when you re-install it.
5. Slide the black plastic dog capture ring up and off the agitator assembly. Notice that the black ring has tabs that follow alignment grooves in outer agitator ratchet assembly body.
6. Swap in the new dogs one by one aligning them the same as the old dogs. My older dogs were a slightly different color so it was easy to tell the old from the new.
7. Replace black plastic agitator dog capture ring. Slide it back down into place.
8. Install the agitator ratchet assembly, lining it up with the plastic tabs mentioned in step four.
9. Replace the bolt and its rubber washer. Hand tighten firmly. You want it to just start compressing the washer. Hold the lower agitator to prevent it from rotating as you tighten.
10. Replace the Cap, from step two, making sure it is pushed flush all the way around.
11. install the fabric softener dispenser, by setting it on top, and then pushing its lock ring down.
12. Test the unit by rotating the entire agitator back and forth. You will notice that the dogs release one way and catch the other.
