June 8
Today is Saturday and I am sick as a dog. We all seem to have the same
upper respiratory problems, Jonah having begun the symptoms first of
course, several weeks ago in fact: coughing, sore throat, stuffed head,
achy feeling in general, etc. Basic flu like symptoms. Yesterday the
engineer from Suva (who worked on our transmission last week when we were
in Suva) came and removed the transmission. Nalin is a very nice guy, of
Indian heritage, and educated in Vancouver since he was 17. As such he
speaks not only excellent English, but American/Canadian English not
Aussie/Kiwi English which is the dominant variety around here.
Anyway, he arrived at 7am yesterday which itself was a shock since Suva is
a 3 hour drive. He says he left at 4am. I was impressed. We discussed the
situation and he got to work removing the transmission. He removed the
reduction housing first, which is the only part he removed in Suva to
change the oil seals and bearings. Another thing they did in Suva last
week was to build up the shaft in the reduction housing which holds the
shaft coupling to the reduction housing. The threads had stripped and they
re-cut it with new threads after building it up and replaced the nut,
which had been worn and distended.
But he didn't remove the entire transmission because it is very very
difficult and I was told by several people that if the problem was simply
he oil seal (at the aft end of the reduction housing) then it could be
fixed without removing the transmission. I asked Nalin about this and he
said yes, it would be easier and did not really try to dissuade me from
that approach. Now his boss is telling me this was a bad decision on my
part and that whatever caused the coupling shaft to come loose it was
certainly NOT the way it was reassembled or reinstalled. He says the
problem is probably either in the main part of the transmission (which we
never removed) or is a slightly bent prop shaft.
Now the thing is when I ask Nalin about this he cannot seem to give any
THEORY or potential explanation of what type of damage in the main gearbox
could have caused this problem, TWICE now. He thinks it is the shaft of
course. Neither Nalin nor his boss were willing to allow, even slightly,
that it MIGHT be that the unit was not re-assembled properly. This caused
the boss and I to exchange some less then friendly words on the phone, but
Nalin keeps his cool and I believe he will not B.S. me. The thing is I have
no way of knowing what really caused it. One possible salient fact I have
not mentioned so far is that we found one of the four coupling bolts in
the bilge after the noise started. There are supposed to be four bolts
holding the prop shaft to the transmission. Why one of them fell off I
cannot say, but the man who attached those bolts, and his boss, don't seem
to think the loss of one of them could be a contributing factor. I just
don't know, but it seems an odd coincidence.
The way it stands now is that the transmission is back in Suva now and
they will take it apart, examine it carefully, try to determine if there
is any possible way that some parts (which are presumably out of tolerance
or in some other way damaged or deformed) in the gearbox have managed to
cause the shaft coupling to come loose from the reduction housing. Like I
said, I don't see how this is possible as the two sections of the
transmission are totally separate - I just don't see how it can happen.
But as the boss pointed out to me I have already admitted I don't know
anything about transmissions!
I have agreed to wait for their analysis on Monday and if they cannot
explain the damage after examining the transmission I will have the boat
hauled out of the water so we can remove the prop shaft and have it
checked out. If it is not straight they should be able to fix it on a
lathe. If it IS straight, I don't know what to do because then we have no
clear explanation of why the coupling failed. But as I said, certainly an
obvious possibility is that it was simply not re-assembled properly, a
supposition the engineers will not even acknowledge as a possibility. Of
course, if it is straight then we will have wasted a nice sum of money,
perhaps about US$1,500. Not to mention we have to empty out our freezer
full of meat because once the boat is out of the water the freezer will
not operate (we have a space in a shore-based freezer lined up already).
Next we have to check into the hotel next door as the other thing which
won't work when the boat is on the water are the toilets, and I simply
cannot sleep somewhere without a toilet, especially when that toilet is at
the bottom of a rickety ladder and it is 3am! Anyway, we should know more
on Monday afternoon.
