Re: Vetus Alarm

Duane Siegfri
 

I'll chime in here with one more thought.  A "low flow" alarm won't help with an over-temperature problem with the transmission.

I had a situation where the tranny heat exchanger rusted out and the flow in the seawater hose sucked out the transmission oil, which overheated the tranny resulting in a ruined transmission.  If I had another heat alarm on the transmission, it might have protected me from the failure.

On the good side, I have a very new transmission and damper plate.

Hi,
Not that it is critical other than it helps for identification, the smaller gear on a shaft, engaging with a larger gear is known as a pinion. If you google the word you will see they come in a variety of shapes and sizes. That is my understanding.

Alan,

Not to get all mechanically nerdy on you, but the "worm" is the helical drive piece on the input shaft, the "worm gear" is round brass part on the output shaft you are referring to as a "spur gear." Again, being very technical, a "spur gear" has a very different tooth geometry than a "worm gear." and is not used with a worm drive.

Gears are round things with teeth around the edge, the "worm" in a "worm drive" is--technically--not a gear.

Especially in the Leroy-Somers boxes, I completely agree the worm does not wear at any significant rate.  It's made of steel. The brass gear (by whatever name) is the part that wears.

If I confused anybody by being overly jargon-ish in my writing, the part I was referring to was the round gear made of brass with teeth in the edges connected to the output shaft of the gearbox.  NOT the helical part off to the side that is driven by the motor.

Worn Worm Gears in Furling Gearboxes

greatketch@...
 

A question came up a short time ago about how much wear was "too much" on the brass worm gears in the Leroy-Somer gear boxes used on the SM mainsail furlers.  At the time there were no good answers posted.


I have been servicing mine, and had the opportunity to compare my installed worm gears (which are relatively new) to much older ones that had been replaced by the previous owner and put in the emergency spare parts box.  The criteria to look for was immediately obvious with new and old side by side.


The attached photo will show the difference.  The new worm gear has flats on the top of the teeth (on the right in the photo).  As the gear ages it loses material from the sides of the teeth, and the teeth get thiner, eventually wearing until they are sharply pointed on top (on the left in the photo).


A good criteria to use for replacement would be when the teeth first lose that "flat top".  After that, wear will accelerate.  As the teeth get shorter, the worm engages less area on each tooth of the worm gear. As the teeth start to get shorter, the risk of them failing to mesh properly with the worm becomes higher.


I am sure a Leroy-Somers factory technician would have a more sophisticated criteria, but this seems a reasonable answer for our application.

Re: [Amel Yacht Owners] Re: Speaking of temperatures and alarms

Ian,

The anchor I like is a Mantus.  Similar in looks to a Rocna, in my experience the Mantus sets even faster and (when needed) on a shorter scope.  If you follow the  Manus recommendation for sizing, you'll have an anchor with a larger surface area buried in the seabed, which is what counts for keeping the boat in one place.

How much better than a Rocna?  That's hard for me to quantify. The difference is not huge, but I think it is very real. Obviously none of us have much experience with the different anchors--at the same time--in the same place--from the same boat.  But I have used both quite a bit.  

I would say the Ronca always sets and holds the first time every time.  Well... except for that time in the really soft mud in the Harness River, oh, and that time in the shallow sand in Bottom Harbor, or that time...  You get the idea.  It is perfect, except when there is a good reason for it not to be.

The Mantus has no "excepts" for me in that story.  Someday, there will be some, I am sure. Nothing is really perfect.

The only other anchors I have personnel cruising experience with are CQR and Bruce.  They, of course, work most of the time, but they don't come close to any of the modern designs under most conditions.  There are lots of others I can not say good or bad things about because I have not used them.

I think by the time you are done shopping, this is such a competitive business, prices are not very different.

Hi Craig,
I'll have to look it up when I get back to Kristy.  It has an arm that hangs down into the hose and is deflected by the flow of water.  Decreased flow->no deflection   ->alarm sounds.

Re: [Amel Yacht Owners] Plug 12V Sharki [1 Attachment]

Mark Pitt
 

This is an Italian Type L grounded plug/socket standard, CEI 23-16/VII, that includes two styles rated at 10 and 16 amps.  The Amel ones are 10 amp.  I have purchased the Btinico brand of these plugs ( both in the US and in Europe) when I have added fans and other devices.  It is easy to make a pigtail to convert from this plug to standard 12 volt banana plug.

Anybody knows what kind of plug fits into the tree-pin plug socket of the Amel Sharki?
Picture of the plug socket attached. There are 3 such sockets, one in the front electric panel for the mast electric, one at the main electric table and one in the after cabin. Each has 3 pins with (+) in the middle and both (-) left and right.


The locations of the plug sockets are rather small to change these sockets for a usual modern 12V round shaped socket.

I would like to echo Craig’s inquiry - we’re very interested in knowing what alarms you found worked well.  Do you have any photos of the set up?

Thanks for sharing your experience.

Re: Bilge Pump Quit

HI Ken,
You don't describe how the gear is broken. If the problem is that the gear portion is sliding on the inner disc it is an easy DIY fix - search my earlier posts on how to do it. Even if the gear ring is broken you may be able to fix it in similar fashion.
Good luck,

Our bilge pump was running for what seemed a long time.  So I went down to see what was up.  I found the motor running, but not pumping.  The motor drive a plastic gear that broke.

Does anyone know where I can get this part, or maybe I have to get a new bilge pump.  :)

Hello,

In the meantime, Amel sav have confirmed the running rigging measurements for Amel54,  if anyone interested. Have not compared to the SM ones.
Currently in French... but will aim to provide a translation when i get the chance to do it.
filed under running rigging folder in files.

Remember that Amel designed the mainsail and mizzen sail halyards to be less than full length...they are designed to be used with small line attached to lower and raise the main and mizzen.

Dear all,


After owning the 1981 Maramu called Popeye for 7 years we have just sold her to an Australian couple called David and Maddy Baddiley who will take her to Brisbane. She was listed on the market for 4 weeks.


Thank you to those who have given advice since we bought Popeye. Work commitments mean we haven't had time to use her this year and it is such a shame to leave a boat like that sitting in a marina berth.


We hope to one day have an Amel again when we have more free time.


Thanks again for being such a good forum.


Best wishes


John, Maramu #91, Popeye, Port Douglas, Australia
