Just purchased a used 98 Tiger River Bengal with a broken, stuck diverter. The adjustment lever and escutcheon popped off w/ no problem, and the retaining ring slid out easily. The diverter is broken, and is REALLY stuck in the tube. I don't want to dig to get it out, ruining the tube, and attempts to pull it out w/ pliers (hey, it's already broken - who cares if it gets damaged further by pliers) haven't worked. Anything I can pour down the tube to loosen the rubber seal ring that probably hasn't moved for 'years'? Any recommendation on dismantling from beneath and tapping up from below. I figured there was SOMEONE who has run into this, as I have been amazed with some of the offered solutions here. I'll take one of those... Thanks in advance for ANY help whatsoever.
