Wendy G Defiance , OH April 14, 2017 Appliance: Model WDSE3120B2WW I was spinning each load twice to reduce moisture in items The agitator was quick to remove and replace - 5 minutes at the most. However the Agitator Coupling was a different matter. It would have been about a 5-10 minute job if the coupler was not caked with nasty hard junk and rust under that. I think the top crust was a mass of hardened lint and grease. Before I could start removing the gunk, I actually had to look at the video to see what the top of the coupler was supposed to look. Once I got the gunk off, I had a rust problem.None of my sockets would fit, so back to the video I went to see what size the repair guy used. However the socket he used would not fit on the bolt due to the rust. So I used Naval Jelly to get rid of the rust. That allowed me to get the wrench on. But when I tried turning it, it wouldn't budge. So out came the WD-40, which I covered the bolt area with. I tapped it with the wrench a couple times in an attempt to break up any more rust coatings I could not get to. Then I went back to the video to see which direction the bolt was being turned. So one more time I put the wrench on the bolt then tapped the end of the handle lightly with a hammer until it started turning. Once I got that done it was smooth sailing.
