Old weaver hatches

[ceedee1108]

Does anyone know how to dimantle weaver hatch latches
The older weaver hatches on my yacht have started leaking through the 4 latches.
I can not work out how to dimantle the latches to re seal them. Has anyone done this before.

I seem to recall they had a single screw on the underside which when removed allowed the handle to come off and the shaft part to be pushed up through the polycarbonate. The shaft had a single oring seal which you can buy at any bearing services store.
