Alright. We are not quite there, but close. I replaced all of the seals in the gearcase. I wasn't sure if I got the spin gear back in the right position if that's possible. I had to spin it around a little before it "fell into place", but it was rotated differently that when I took it out. The gearcase appeared to spin ok after assembly.
I replaced the oil seals in the top of the drive tube in addition to the gearcase seals.
I also got the agitator dogs replaced. It turns out the plastic white fingers that stick up and protrude through the agitator "clutch?" (the part where the dogs attach) were smashed down for some reason. The washer has never been apart since I bought it new. A good tap with a screw driver to clean them up allowed the agitator to pop apart.
The washer is reassembled and not leaking at the moment, but it is making a clicking sound during agitation. I'm not sure if this due to a possible mis-alignment in the gearcase as mentioned above, or if this is due to a mis-alignment between the drive tube and clutch. We are filling, draining, spinning, and agitating with a loud click. Any thoughts?
Thanks so much for all of the help!
