"The front cell's rear element unscrews easily..."
"Second element just unscrews from the front group cell with fingers."
Ha! Mine proved to be a bit more stubborn. It took two rubber gloves, a jar opener mat cut in two, two days of alternating treatments of mild heat and Liquid Wrench (sparingly applied to the joint), and finally a few light taps around the perimeter of the front cell with a rubber mallet.
Regardless, having confirmation I was disassembling correctly was a big help! Thanks again to you both!
