Is there a trick to installing a new wigwag in an older Kenmore washer? I got the old one out with some difficulty, although neither the old wigwag or the shaft show any signs of corrosion. I noted the split in the end of the shaft and thought the new one would slide right on, but I cannot get it to go down at all. Due to the location in the machine, it is very difficult to apply much downward pressure on it. Any ideas would be greatly appreciated!

Thanks Gene for your suggestions. I have not started the locking screw yet and the plunger shafts are started up into the solenoids. I finally got the wigwag started down on the shaft by employing a crowbar and a piece of 2x4. That thing fits so tight on the shaft I can't imagine even needing the locking screw. By pulling up on the crowbar with all my might, enough to lift the rear of the machine off the ground, I was able to get the wigwag to probably 3/16" of where it needs to be. I hope I don't pull the entire transmission off the machine with all the effort required to slide the wigwag on. I have even lubricated the shaft to try and get the wigwag to slide easier, but I don't think it helped much. Seems like it would have helped to have the hole in the wigwag be just a bit larger in diameter.

Thanks Gene for all your helpful suggestions. Early this morning, while the metal in the shaft was in a contracted state from the overnight coolness, I was able to finally force the wigwag on the rest of the way, secure the locking screw, and reattach the wires (in the right order!). The machine still ran after all the abuse I have been giving it, and what's better, the spin cycle actually works... Yeah!
