Finally got the agitator off! I couldn't get it off last Saturday, so I sprayed WD-40 down the hole where the fabric softener dispenser was supposed to screw on and let it sit all week.
Tried again this morning and still couldn't get it up. Then I tried the towel and hot water method I read about on here, and it was still stuck. Then, I tried putting a 2x4 across the top and pulling it up with the ratcheting straps, but it was still stuck. I put the towel and hot water again, and let it sit while I had lunch and a nap.
Then, I got up and tried again with the straps about an hour ago, and finally got it up.
Those garage pics were when I first moved here last year, before I put up all my TV repair equipment in the back corner (3rd pic). I like all sorts of old technology, but this is the first time I've tried to restore a washing machine...
Yep, I've been there a few times with a stuck on agitator. Back in those days I didn't have the internet to lend me advice.
I had Liquid wrench and a rubber mallet.
The few times I couldn't get action with that I just took a hammer to it or a recip saw and pulverized it into many pieces then bought a new agitator because back then they were still readily available stocked items.
You're showing you have patience and thats good. You need that when working with such things.
