I recently serviced both main furling and outhaul gears and motors. I found the aluminium shaft on the furling motor very difficult to remove. It was soaked 48 hours in diesel and then pressed out with a hydraulic press, but it took a lot of pressure. Eventually it came free. Whilst the outhaul shaft came up and out with some gentle taps, being stainless steel! I think that this mast furler should be pulled apart more often to avoid the aluminium seizing in place, maybe every two years, just drop it, move the shaft up and down, check the gear box and lip seal. Alternatively have a stainless shaft made.
Fortunately I had a spare gear box on board as one was in very poor shape with bad corrosion on the aluminium. However all went well and both are back and fully functional with new shaft seals. Although I now do not have a spare aboard. Something that I would like to have if I go off the beaten track.
I decided to make a cover out of some PVC I had kicking around to protect the boom furling one from the elements, as shown in the pictures. There is a drain hole at the bottom of the GRP cover in case some water gets in. It is quite small maybe 8mm. It could be widened to say 12mm if required.
Has anyone tried this? If so was it a success or does it just deprive the gear box of ventilation?
