Re: Bow Thruster Siezed

Hi Ellen,
             There might be another way, but you will need a lot of time energy and patience. The bow thruster on my SM jammed solid a few years ago in Mexico and it would not move. After several days trying to get it out, It became obvious that any more dropping or hammering was going to damage the boat.
So, I removed it complete with the motor stuck to the shaft from the inside of the boat. It took a full three days, dawn to dusk to remove and replace.
The complete unit weighs around 80lbs . You need to be really careful to mark all the electrical cables as on the SM there were lots of black ones!
If you consider going this way, be sure that all power is isolated.
The position of the limit switches is really important to ensure that the bow thruster will retract properly when serviced and replaced.
It is a nightmare of a job but it can be done.
When we finally got it out it couldn't be pulled or pressed apart, so it had to heated to white hot before it broke apart.

Good luck.

Parts or replacements for Antal 120x18 genoa sheet blocks

Ryan Meador
 

Hi all,

As we prepare for the sailing season this spring, we've noticed our genoa sheet blocks are in pretty bad shape.  Some of the ball bearings are cracked or crushed.  At the very least, I think the bearings need to be replaced.  I wouldn't be opposed to replacing the whole blocks.

Does anyone know where I can get replacements?  I've looked around on the Antal website and they don't seem to make this exact model anymore (they still make it in larger sizes though).  This block is the closest I've been able to find, but it looks like the shackle can only be at 90 degree angles (the existing blocks have the shackle set at about 45 degrees and it doesn't seem possible to rotate).  Would it work?  That shackle angle seems pretty important to me.  I also discovered this replacement sheave which looks like it might fit our existing blocks, but I'd probably have to contact Antal to confirm.

Thanks,

Ryan and Kelly

Re: Bow Thruster Siezed

 

I saw your photo with the jack pushing the coupling upward. Am I mistaken that it has moved 6-8mm?

This should be a warning to everyone with a bow thruster prior to the Side-Power in A-54's that service on this valuable component is important. I recommend service every 2 years.

Back to your issue. Of course, I do not know all of the details and long-distance diagnosis is problematic, but here are a few things that you may not know:
  1. That bow thruster tube is probably impossible to get at any price. It may be possible that Amel will either have one sitting on a shelf or make one. I doubt it, but you should write and ask SAV"at"amel.fr.
  2. Later model bow thrusters had a 60mm composite tube. Amel fabricated a 60mm tool for the purpose of removing a stuck tube from the motor base of later model bow thrusters. It is possible to make your self or get from Amel when they reopen from the current shut down.

  3. The most important thing you need in this process is patience. How long have you left the jack under pressure?
  4. Don't use heat as you will likely damage the tube and of course cutting it will put you out of service forever.
  5. You might consider sealing the bow thruster from the outside with resin and glass which you remove later when you have a solution.
  6. There is a high-carbon steel shaft inside the composite tube.
  7. You might want to look at the high-quality photos here:  http://nikimat.com/bow_thruster_overhaul.html

Hi everyone! 

I was hoping somebody could help with a particularly troublesome bow thruster. We bought out Mango 3 years ago and we have been doing short sails while slowly refurbishing her. 

We have a number of times attempted to remove the bow thruster foot assembly to no avail. This past winter it started leaking so now it has to be removed to replace the seals. I've no idea if the previous owner had ever removed it.

We have removed the 4 bolts but the shaft is jammed in the rust encrusted top motor assembly. We have since
- applied vibration with a sander
- sprayed penetrative oil in the 4 holes (every day for a week)
- tapped with a hammer
- dropped it about 10 times
- put a stick between the bottom v section and the hull while jacking up the motor assembly from the inside. Slowly applying more press and oil over a week.

It hasn't moved at all. The leak is unacceptable so we are now considering cutting the shaft or motor holder. Really not ideal. 

Anyone have suggestions of what to try next? 
What is the black shaft made from?  What's inside the composite shaft?
Can you buy this foot assembly from Amel? Idea on cost?

 Thanks for any help!

Re: Windlass/Genoa Furler electrical problem, circuit breaker bad?

Alan Leslie
 

We have had a genoa furling solenoid fail on that board. We now carry two spares.
I concur with Bill, the whole assembly comes out with a long loom, very easy to work on, and of course for testing voltages etc.
Same goes for the board that holds the main furler solenoids in the top of the aft wall of the forward head.
Very well thought out - more Amel stuff to appreciate!

Re: Gas springs on the aft Lasarett

Paul! I think of losing toes every time I close that thing :) But thinking on it now, it would be far easier and not mess with the access like struts would, if you just took a foot long piece of fat pool noodle and tied it to one corner of the locker with a short line. When you open it, you flip up the noodle. If it falls, the noodle takes the brunt of it, not your toe....

We are working on an Amel 54 and have found the Diruptor 60 AMP breaker for the staysail furler has failed.  Getting Diruptor breakers in the USA is always a challenge, but between this larger size breaker and the general disruptions right now I am coming up totally blank.  Any suggestions would be greatly appreciated.  This is a Diruptor “Yellow Series Breaker”, also called the “7500 series”  Single pole, 60 Amp.

Hi Did you ask Maud if she can get you one? Considering the price of FedEx, I would order a few other breakers at the same time.

Re: Chain counter

Hi William,

 

ON SM384 the Display of meters will power off if you press and hold the button for about 15 seconds. The amber LED on the port side of windlass itself will go out if I turn off both the switch and the circuit breaker for the “Guindeau” (surely spelled wrong as I’m not aboard), in the forward cabin, forward, port locker. Hope this helps,

Davi - to add to Jamie's comment, I've had 4 or 5 breakers fail since my boat reached about 15 years old. Your A54 is getting to that point, so I wouldn't consider it surprising to see a failure. Fortunately, and as designed, the failures leave the breaker open.
Craig

Re: Windlass/Genoa Furler electrical problem, circuit breaker bad?

 

Davi,

That entire board is removable. Look for the single black thumbscrew inside the door where the breaker is located. I have known this breaker to fail, but it is unusual.

BTW, when you have the board loose, there is plenty of wire to pull that board out so that you can operate on it. 

Best,

Hey Amelians! So I'm stuck here in total lockdown in Greece (really can't complain, it's amazing), so it's not a tragedy, but the circuit breaker on the windlass/genoa circuit of our SM is tripped at some point this winter (in the last few weeks sometime) and won't stay in the up/on position. Being in lockdown, getting parts is almost impossible, but I do have a spare 100A circuit breaker that would fit. Since the space to install is very limited (I can't even put a multimeter probe on the top of the breaker without pulling things out), I was hoping I could get confirmation from y'all that the circuit breaker is the most likely culprit....

SYMPTOMS: When I use the dashboard switches for windlass or genoa (or the foot switch for the windlass also), the solenoids in the cabinet click happily and strongly. But the breaker stays down, and nothing will keep it up. When I cut the 24v power at the battery banks, the circuit breaker still will not remain on. If I hold the breaker open/up and have someone activate the switches in the cockpit, still nothing but clicking from the solenoids. 

Anyone see a problem with swapping out that breaker as the fix? How often do they fail? I don't remember a broken breaker being a very common thing in my life, so just wondering before I wedge myself up there and start hammering :D 

Many thanks!

Re: Windlass/Genoa Furler electrical problem, circuit breaker bad?

Davi, almost certainly it is a defective breaker. The breaker should stay on if you flip it on WITHOUT power to the circuit. The fact that it always stays off indicates a broken latching mechanism in the breaker.
Good luck with replacement and you "stay" in Greece.
Stay safe.

Hey there, and thanks! Our windlass has no switch on top, so that's out. I'm betting on the bad circuit breaker still.... 

Re: Windlass/Genoa Furler electrical problem, circuit breaker bad?

DEARS, 
it could be that the  two windlass  switches on the top of the anchor windlass maight  allow some water infiltration that  causes the problems of the short circuit with the relative high ampere flux. 
We had to substitute the switches  .

Hi Davi,

If it is a swap to a new breaker of the same capacity that is a reasonable test with low risk. Just do not hold it up if it pops.

Hey Danny, just to clarify, the breaker there now is 100A, so this is a straightforward swap. I'm trying to get my head around the odds it is the breaker. Both windlass and genoa worked fine a week before this. Wouldn't the breaker stay up if the battery power was cut off to the circuit if it was still good, even if there were a short? There should be no power going to the devices, hence no short to flip the breaker...?
