<span style="font-family: arial,helvetica,sans-serif; font-size: small;">Jetcone, check out the post above (Post# 744269) from PhilR. He shows how it's done. Usually when this is happening though that brass keyway in the top of the shaft is either missing or broken. Sometimes these shafts just like turning through anyway. I always without even checking use a vice grip on the bottom in order to get maximum leverage and keep stress off the other parts.</span>
<span style="font-family: Arial; font-size: x-small;"><span style="font-family: arial,helvetica,sans-serif; font-size: small;">I've said this here before but one thing I always do when I put the top end of these machines back together is to cut out from a piece of thin rubber a washer that fits directly under the pulsator nut. Originally these had a thin plastic washer that deteriorated over time, that nut will practically fuse to the cone over time. I also use light threadlocker inside the nut, this keeps it from rusting back onto the shaft and facilitates easier removing in the future if necessary. I keep my vice grips locked on the shaft until I'm done because you don't want to tighten it good enough to prevent cone hop.</span>
