Paul,

Lot's of good information on the main furler in this thread:  https://amelyachtowners.groups.io/g/main/topic/29770769#43884

and in this Photo Album:  https://amelyachtowners.groups.io/g/main/album?id=84576

My furler was completely seized up so I just completely overhauled it.   My gearbox, however, appeared to be fine so I just re-greased it and re-installed it.
