I've rebuilt my PHII's several times, and you really have to
disassemble it to lube the piston properly. It sure would be nice if I
could figure out how to do it without disassembling though... I
basically let it go a couple of years then rebuild it, lubing it at
that time. In the interim, I lube the shaft and the wet/dry rotor
several times.

So, assuming I misremember (happens more and more lately), where,
exactly, do I put this heavy squirt? As I (think I) understand how
this thing works, if I were to take it off the base as I did, and
merely put a large dollop of the grease in it, reassemble, and pump
away, it would immediately go out the joker, other than that which
managed to scrape against the sides.

Or, is there somewhere else I put it? As I did it, I put a pretty good
layer around the cylinder. My first attempt (years ago, now) had me
putting it down the flush/dry valve, and the output to the bowl,
because I couldn't see anywhere else (which was supposed to be so easy)
which, of course, thoroughly lubed the ball and seat and made the seal
not very good there.
