20th January

We had the header tank removed from the engine by
0800 – not the simplest of tasks as the securing bolts are pretty inaccessible.
The mating surfaces were cleaned up then came the task of removing the original
cap insert. More fun but with the judicious use of a hacksaw and later some
brute force it was removed without any apparent damage to the seating. A couple
of hours later the seat had been cleaned and honed so that the new insert was a
good fit. Then we ran into difficulties as the epoxy we had was not rated at
the correct temperature, however two hours later and almost a complete circuit
of the island we found the correct glue – thank heavens we had a car! The
system including the new expansion tank was pre fitted to get all the correct
angles then with great trepidation the epoxy was applied. This is always a
worry as there is no second go available with this type of glue. Anyway the
parts all fitted together well and will rest overnight for the epoxy to cure
before being finally installed tomorrow. There is no doubt the new system is
light years ahead of the old but our original estimate of four hours to install
has ballooned out to a day and a bit. The proof of the pudding will of course
be when we start the system up again which won’t be until Thursday as we
need to allow all the joints to thoroughly cure first. The boat is now in a
reasonable state of disarray as all the lockers with spares are open and the
contents liberally spread around as we searched for bits. Whilst the header
tank was off the engine we also replaced the thermostat which sits underneath
it. Although the original is only a couple of years old it seemed prudent to
fit the spare whilst we had access to it. We still have some ants on board and
one of our tasks over the next couple of days is to find some ant traps. We
think they originated in |
