The ring was installed backwards or maybe it was broken off on the end.
In either case the cap/plug absolutely would not turn out.


As I understand the video, the cap does not have any threads, so there
is no in or out. The locking wire can be installed either way. In the
video, Keith takes the wrong guess. The only consequence is that he
has to rotate the cap almost one full turn before he finds the end of
the locking wire.


He talks about a leaded wire. I highly doubt that has the shear
strength to withstand the force exerted by the cylinder. Remember unlike
the seal which only has to deal with the pressure of the fluid that lock
ring would have to deal with the force of the entire diameter of the
piston. I know the wire in mine was not particularly strong wire, and
it is with 100% absolute certainty threaded.
