IF you haven't taken that winch apart for decade and it still works alright, you should be PRAISING Lewmar :^)))
I actually think it's a pretty good design (any your experience with its durability is testament to that. That fitting could well have corroded shut with a different "cap".
Be careful when you reassemble that, as others have suggested, you don't overtighten and that don't cross thread anything.
Also -- use the right grease and other lubricants; and, DON'T GOOP it up with too much lubricant. Lewmar's site had a number of videos that make that clear. There are others on the web. TOO much lubricant is worse than a little too little.
