The Penta-Vane on my working 1980s Kenmore 60 Series slips occasionally as it agitates. It makes a loud clicking sound as it slips. I have no repair experience but would like to fix it myself. What's the problem and how can I repair it? How do I get the agitator off the drive shaft? I tried lifting it but it won't budge. I read that possibly it's stuck on the shaft splines? Or maybe it's the transmission that slipping? The main problem for now is how do I remove the Penta-Vane agitator?
