My question: Should I remove the old balun or may I keep it, i.e. does
it has any influence even if the coax is removed?

It is unclear where you have connected your ladder-
line at the antenna end. Is it connected through the
coax connector or does it bypass the balun and connect
directly to the antenna wire, i.e. are you trying to
use the old balun as your center insulator?

This is what I intended to do, using the 'eyelets' on the balun to
hold each leg and to connect the ladder line to them. Purely a
mechanical solution.

But since there is a 0 ohms (DC) resistance between the two posts on
the balun, I am concerned abour adverse effects.

You need to measure those impedances at the frequencies of
interest. If the antenna feedpoint impedance is much, much
lower than the impedance looking back into the old balun,
you don't have anything to worry about. You can determine
those impedances with a lot of time and effort. Or you can
remove the balun and install an insulator. Personally, I
would install the free insulator out of my junk box. :-)

Open the box, snip the wire.
