I got the new seal in--used a little "plumber's grease" to help get everything down over the shaft. Put on the new drive block and cleaned everything. I checked all the hoses for wear, and cleaned out the middle of the inner tub with steel wool, because there was rust in the tube. Then I took apart the agitator to check the condition of the "dogs". The agitator worked fine but just wanted to see for myself. Getting it back together was "fun" until I realized you have to hold the two parts horizontally to do it.
After slipping the cabinet on, I THEN unscrewed the console to access the large clips that hold the cabinet to the back. It was easier to do it this way, because it kept the console with the cabinet while I was working, and not flopping all over the place.
Here's another trick: when taking that spanner nut off, I could only get it to move a tiny fraction. I sprayed more Wd40 and gave it a few minutes to work. Then I banged on the wrench in the opposite direction, (to tighten). Then I banged back the other way, and did it again. That worked fantasically. It moved right away.
Two weeks ago I had no idea what I was doing. I actually had tried to GIVE away the dryer but nobody wanted it! They want the "new" stuff, with all the digital features on them. Which are controlled by a computer module, which costs about $200 to replace.
When I went to return the spanner wrench to the guy that lent it to me, he had a set exactly like mine that he wanted almost $400 for.
It cost me less than $40 to fix my washer, and I learned something.
