rotostay roller furler

[masterofnone]

Hi my furlers are a bit stiff, I searched it 'wash out with freshwater' but on the bottom of them their are 4 holes that appear to have grease in them. should I rinse out, lube with wd40 then repack with winch grease? can I do this without dismanting?

If you know the particular model of Rotostay, there are a few knowledgeable folks here who may just have an exploded drawing in pdf format that would help.
If it's the FS4 then you'll find a complete refurb documented on http://corribee.org/technical/roller-reefing/ which includes drawings and photos.
