Apparently, there is no available Lewmar
hatch specialist on the forum. I'm sorry you have not gotten a response.
Let's try to think it through.
From the looks of it, the red tag simply stops the rotation of the handles, so the bolt stays extended. It should insert itself into a non-rotating part when you lock the hatch.
One avenue is to take it apart and see why the red tab is not stopping the rotation. It could be that the new core
doesn't have a notch for the tab to go into. Another approach would be to reuse the core
and lower parts
, while replacing the handle on top that has been UV damaged. A third would be to repair the damaged handles with epoxy
, either molded around them or painted on in several layers.
At any rate, if you are careful in your disassembly, in a place in which small spring loaded parts
cannot run and hide (I used to use a buttoned up tent), you have little to lose in figuring out how the mechanism works. Therein lies the clue to how to make it work
. Good luck with it.
