Thanks, the hex. nut was easy to remove. Now all I have to do is to get
some Teflon grease and be careful not to twist the O'ring when screwing back
the hex nut.

lubricate the inside of the pump's cylinder and piston I have no other

then to take the pump apart. Maybe someone has a better way to
lubricate
the moving parts.

No need to take the pump apart...just remove the top. And on a Jabsco,
it's easy: on older models, remove the 6 six screws and lift it...newer
models, just loosen the hex nut and lift it. Put a healthy squirt of the
grease into the pump...pump a few time to spread it all over the inside
of the cylinder...replace the top. Should take all of 10 minutes, if
that long.
