Replacing the cutless bearing was meant to be difficult, but not the ordeal
it turned out to be. Access is very difficult on the Baba 30, you have to climb
down into the lazaret and stoop/crawl to the bottom, I pushed one leg through
the engine bulkhead to rest between the engine and the port side of the engine.
After ten minutes it becomes very difficult. The gearbox flange is never
closer than arms length.
The haulout started badly with me reversing out from my pontoon finger and
being caught by a large gust of wind that sent me the wrong way down the berths
to a dead end, pointing the wrong way. Eventually I was in the hoist and the
crew at Liverpool marina did an excellent job of lifting and chocking me up.
Next, the shaft had to come out, this wasn't going to happen, the coupling
flange had been heat shrunk onto the shaft, then pinned on by an Allen key that
shredded at the first attempt to loosen it. At this stage I called on Geoff
Dixon, the local engineer for help, Geoff, who I might refer to as St Geoff from
now on, did a fantastic job. I cut the prop shaft with a hacksaw (2 hours) and
he made me a new one.
The cutless bearing itself wouldn't come out so that also had to be hacksawed
off, a hand held hacksaw blade, the Stanley knife variety was used, this only
took 4 hours. I wish I had know there were two grub screws holding it in place.
Eventually I had it out. Then I found that the bearing had 1 1/4" Inside Dia and
1 7/8 Outside Dia by 4 Inches long. This is very non standard and I had no
chance of getting a replacement on time. It later turned out that Montrose in
Birmingham could have made me one in 1 day, but their machine was waiting parts
and would take a week. I couldn't wait. Geoff then suggested we take my
bearing i had bought in advance that was 2" O/D and turn it down to the correct
size. We would also leave it sticking out an inch ( as it was 5" long) so that
it could be removed easily next time.
On checking the stuffing gland it was obvious that it was reaching retirement
age. I replaced it with a PSS dripless gland, expensive but should be worth it
in the long run. I also added a flexible coupling as it did not have one
originally.
While out, I serviced a few sea cocks and replaced one.
A general tidy up in that area and a fresh coat of antifouling and she is
ready to launch. She goes in tomorrow Fri 13th.
