Hello Fabio,

Attaching pictures like that won't work...
We are not able to see them...
Either put a link to a web site, blog, etc. or may be use the Yahoo forum to post them...
Sincerely, Alexandre

Good evening everybody and thank you for
your replies.
What I intend
as the cube (in aluminum) is the following:


The expansion tank is the following:


The oil is not going down from the transmission
cube to the propeller foot...

I don't understand why, the only thinking
now is that in 2011 the transmission have been disassembled
and the conical gasket between the cube and the lower part
has been substituted with a big oring as we couldn't
find the original one at that time.... The mechanic the made
the job at that time told me today that this cannot cause
and oil blockage and also the transmission properly worked
for 5 years...I hope he is right!

Now I was thinking to try putting the oil with
a pressure pump from the lower hole, the one used to
discharge the oil, in order to see if the oil is going up
till the cube transmission and verify that there isn't
any obstruction.
I also didn't tried
with a warm oil as suggested by Olivier and shall
try....
P.s. I could not verify
the exact quantity of oil drained from the transmission as
someone in the shipyard thrown it away before I
could measure it.
Suggestions are always welcome.

Thanks and regards.
Fabio

Good
evening Fabio,
first
question: do you know how much oil you drained from the
transmission?The
first Santorins, maybe up to n°40, had the first type of
transmission, with aluminum housing. Could you post a
picture of the upper part of the
transmission?This
transmission holds probably less than 8 liters. However,
filling the transmission with warm oil and moving the
propeller by hand while filling will help you. (And...be
patient...)How
do you warm up the oil? Put it in black jerrycans in the
sunlight.
Your
old mechanic is right: don't fill up the reservoir, but
only up to the first third. The oil needs to
expand.The
oil will never get warmer than 70°C because the lower part
in constantly cooled with seawater. So no problem with the
temperature.
Bon
courage.
Olivier

Hello
everybody,
I'm
in troubles as I drained the oil from the transmission to
change it and I'm not able anymore to fill the
trasmission with the 8 kgs 15W 40 diesel oil as
prescribed.I
started to put the oil and after approx. 3,5kgs the oil
didn't go down. Trasmission cube is full of oil but do
not go down...I tried to take out again the drainage nut on
the keel nearby the propeller thinking about a possible air
bubble but the oil was caming out in very small quantity and
very slowly.Is
there some trick
I do
not know?
And
also, an old experienced mechanics told me that is a mistake
to keep oil in the plastic
in
place
in
the upper reservoir
above the transmission
should
not contain oil
but
should
only
serve as an expansion
vessel for
collecting
the
excess oil which
heats
up and
expands
might
make
working
pressure
causing
the
transmission in high
and harmful
temperatures.
Thanks
in advance for your suggestions.
