[TR] tr-3 lever shocks

[Gary Nafziger]

I'm renewing the lever shocks on my tr-3 project.  I plan on simply draining
the oil and putting in fresh.  I took off the upper lid and simply emptied
it.  There's also a large nut on the side near the bottom which I took off,
removing the valve and spring and drained.  pumping to drain.  While I had the
shock in the vise and everything open I also poured some cleaner in the
top......(hoping to wash out any gunk).......but upon pumping it never pumped
through or came out the bottom.  Are these separate chambers?  and upon
renewing do I fill each chamber separately?  Also what fluid?  I've heard
various choices of oils.

thanks!
