28th April

The servicing is progressing well albeit John is as stiff
as a board from being upside down in the engine room. The main engine was the
centre of attention today with a complete replacement of all the fuel and oil
filters. This was done on a major service basis with all the gaskets and O
rings being replaced – a tedious and fiddly job in awkward places. The
fuel pump was also given an overhaul and new lubricant. A look at the raw water
impellor showed some wear so it was decided to replace it. Another very trying
location with John upside down under the engine again. Managed to drop the old
rotor into the bilge under the engine which is very deep. So had to go fishing
and eventually retrieved it which was essential as it could jam the bilge pump
floats if left rolling around. As the freezer cooling filter was handy to the
upside down position that too was serviced at the same time. Whilst changing
the fuel filters and fuel polisher we managed to top up and bleed the system of
air first go – an almost unheard of occurrence – the gods must have
been keeping an eye on us. A detailed examination of the alternator drive belt
revealed some wear so that will have to be changed to though it will probably
have to wait until tomorrow as the engine is too hot to work on at present. The
drive belt is an interesting arrangement that has not been noticed before as we
have not had to change it – the belt runs an interference fit around some
cooling pipes so one of the pipes has to be removed to replace the belt –
not a common occurrence even though the designers have installed a joint in the
pipe for just that purpose. It would be difficult to replace at sea and impossible
on a hot engine. Once the engine has cooled we can also change out the pencil
zincs in the heat exchangers. The gearbox has been done so apart from a clean
up we should be clear of the machinery spaces tomorrow an be able to get into
the shaft tunnel. We have local carpenter called Jay working today. He has
removed the forward Dorade housing which had a tendency to leak. The whole unit
is being cleaned up and re-bedded in sealant. Although the marina still seems
quite crowded the larger boats are all leaving at a high rate and it is just
the racing boats here for race week that are using the berths temporarily. They
will all disappear at the end of the week and the cat club will look a bit
bare. Hound and Melinka plus two others left this morning for Regards John |
