Winch servicing question

[KenMcCulloch]

Most of our winches are quite straightforward so far as servicing is concerned but these two are a little bit of a mystery. Self tailing Lewmar 34s of unknown vintage but quite posibly dating to 1980 when the boat was commissioned. There is no visible means of dismantlement on the top, no circlips, no bolt heads in the bottom of the socket. Two possibilities occur, one is that they dismantle from underneath, as it were. One of the pair needs to come off anyway to reposition the stripper arm in a more useful orientation, so that is definitely on the agenda. The other possibility is that the tops simply unscrew after hitting the stripper arm anticlockwise with a big soft hammer. There are marks which suggest this has been done in the past.

If anyone has succesfully stripped and rebuilt such machinery it would be good to hear from you.

Fantastic, thanks everyone.

I have a PDF from Lewmar specifically for the 34ST. It has an exploded diagram and maintenance instructions. (PM me with your email address if you want it)

Repositioning the self-tailing head is achieved by adding or removing shims.

Use a small screwdriver to take the black surround, by the winch hole, off. Then you will see a clip, remove that and take the winch apart.

Thanks for that, as you will see from a careful reading of the thread, there are no removable clips, covers, unscrewable rings or similar. The mystery has been resolved to my satisfaction.
