Cautiously optimistic

Today Mary and I had a slightly different excursion around St Helena,
in search of the Hydrolic oil for Fred. It had been suggested that the
PWD garage at Donkey Plains would stock the Hydrolic oil in question.
So we set off by bus from "the Grande Parade", via "Near Three
Tanks",'Whitegate', White Wall Junction,Rosemary Plain to New Ground
Point, from where we had a 15 min walk to Donkey Plain. Why its called
Donkey Plain we will never know; its more like the North Face of
Everest than a plain, and the only living animal there was a Goat!
En route we did our best to understand some of the broader country
Sts dialect used by fellow commuters. Funniest of all was all the chat
about going to the "City" today to do their Xmas shopping!
WE found the PWD garage, and were given a 5 litre bottle of Shell
TELUS T37 Hydrolic Oil, which is what they use for every single
Hydrolic Oil using vehicle. To the point that they drained the oil out
of their new warfside cranes, and replaced it with TELUS T37. They
sometimes used the thinner T26, but have now standardised on the T37,
which is still "nice and thin"!
Back at the boat, after Wahoo Steak and chips at Annes Place, I set
about draining the unit, flushing out the old oil (which measured
about 60ml), and replacing it with the new( which only took about
120ml).
I then went through the Drive unit checks again- Pwer to the motor,
then include the clutch, and reverse polarity etc to check ram
operation, before connecting back to the brains. I then went to 'Power
Drive " mode to check the 1deg and 10deg course change elements. The
first attempt failed, but after losening the bleed nipple, checking
the fluid levels again, we tried again. Turned everything off, and
started over. Success!! The Power steer mode works perfectly, and
returns to midship when auto pressed. We let it auto steer us around
the anchorage for a while and it seems ok. Next we will head out for a
proper sea trial, probably on Boxing Day, and report back. Our thanks
to everyone who has shared ideas, input, and best wishes. We really
appreciate the help, and at his stage , are "cautiously optimistic"!
Love and best wishes to all!
