Determined that I needed to replace 1) clutch assy. and 2) fill switch.
After viewing your videos on how to replace those items, I was fairly confident that I could do it unless some part of my washer, purchased in August, 2000 was so rusted it wouldn't budge. Removing the agitator was easy with a screw driver and 3/4" socket extension & wrench. Disconnected washer and used hand truck to move out onto my porch, which was far roomier. After tilting it over onto it's back and cleaning out all the spider webs, lint, and dirt (missing in your video), I proceeded to swap out the clutch assy. and brake part just as your video showed. For this, it took a screwdriver and a socket set with, I think, a 5/8" socket.
Reassembly was in reverse order and the only problem I had was sliding the shaft into the agitator section, easily fixed with a couple of sprays of WD-40.
Replacing the fill switch went just like the video. The old fill hose was still in good shape, so I reused it to save time. The new switch has a barbed connection for the hose which is a design change, so I used the hose clamp provided with the new hose to insure a tight fit. I'm guessing that the design change was because the old type hose connection eventually leaks enough air pressure to cause problems.
