To fix you furler it will probably take a new motor, and maybe a new gearbox.  I would rebuild the old gear box and carry it as a spare.  I carry a new spare motor, and a spare rebuilt gear box, ready to go in case of a problem.  Someone mentioned that the new motors are a different diameter, and I found this out as well.  I built up the diameter of the the motor where it attaches to the cover attachment with some good tape.  Just about 3 to 4 times around the motor with some good tape and the cover attachment piece fit snugly on the motor.  It was in one of my videos about the Main Sail of a Super Maramu.

Thanks Mike.  I think you may have been able to explain what caused the problem. I know it's been installed for 20years in my case. Upon removing the gearbox and motor to inspect, I found that it was in good order being in the original condition. Cover over the motor still  had the original silicone. 
I may have a engineering workaround to repair the shaft for a spare.

Re: Installing a diesel heater

Hi Paul,

the M12 is installed in my boat but it is a older one, the control units now more different. I have a switch on/off close to the Generator switch in the galley and a temp regulation in all places as also a switch close to the vans at the heat exchangers. I have them marked in the pictures.

Best

Arnold

What size of heater do you have?

On the subject of Leroy Somer furling motors, we learned a bit about them this year--way more than we wanted to.

For the first time since we owned Harmonie, the outhaul motor exhibited classic signs of needing new brushes:  irregular operation.  When I removed the brush holders, oddly, the brushes looked fine. Upon further disassembly the rest of the story was obvious.  25 years of accumulated carbon dust had obstructed the rotation of the armature to the point that the friction shattered the internal magnets. This motor was dead.

Amel shipped us a new motor which fit and works just fine. Key point here:  Whenever changing brushes do not just pull them out of the holder and drop new ones in, but clean out all the dust. Do not let it accumulate inside the motor!  Do not assume that previous owners or mechanics did this correctly.

Lesson learned, we completely disassembled the furling motor (which is identical), and cleaned the inside with vacuum and contact cleaner, dressed and polished the commutator, and tested resistances.  All checked out well, so they should be good for the next 25 years...

Notes on the new motor:  the new Leroy-Somer motor carried the same part number, and was in all key external dimensions identical to the 25 year old original. It mounted and worked just fine. The internals are quite different, however. Key for maintenance is the fact that the brushes are different.  Instead of two externally accessible brushes, the new design requires disassembly of the motor and replacement of the entire internal brush holder assembly because the four (not two!) brushes are welded in place to the holder.  This emphasizes the importance of sending pictures of parts to Amel when ordering.  If you simply order brushes for Leroy-Somer motor Part Number XXX_XXX you might not get what you need.

Other important lessons that would have saved us this cost:
* Electric motors are (almost) forever if regularly cared for.  The furling motors hadn't gotten to the top of our list for a professional rebuild.
* Take stuff apart.  You learn a lot, and this problem could have been avoided if this motor had been on my "take it apart and put it back together for no reason" list.

Dave and All,

 

   I wanted to add a caution and mention that Chlorine can apparently cause corrosion issues with stainless.  Since our stainless keel bolts, nuts and washers are located in the bottom of our water tanks, I am pretty leery about putting a bleach solution, especially a strong one in my water tank.  The soft scrub that I used did contain bleach but was rinsed away as the tank was cleaned to reduce the exposure.  If anyone with a more expert knowledge of the corrosion risks from using Chlorine in our tanks could comment, that would be helpful I think.

Re: Cleaning fresh water tank on my SM2K

Matt & Michelle Day, SM#208 SV Talia
 

Clorine can damage stainless with long duration exposure.  The duration depends on penetration of the passivation layer of the SS.  Once the passivation layer is oxidized, the clorine will pit the SS and increase the risk of stress corrosion cracking.

At the concentration and duration that the group is discussing...we are talking about years to have a detrimental effect.  If one is concerned, you can always re-passivate with citric acid and restart the clock. 

Just my two cents.

Re: Bow Thruster Amel 54

 

Hi Rudi, yes, you need to decouple the lower unit from the motor. In my experience, this will be difficult if it has not been decoupled in a few years. It will very likely require some heavy-duty mechanical pullers. It is likely that you will need to replace the soft coupling when doing this job. 

There is an Amel procedure for decoupling the SidePower Bow Truster, but it is not very complete and probably will not help much. There is a SidePower publication as well. I wrote a procedure including some photos I took, my personal experience in doing this job, SidePower's information and the Amel procedure. It is in my Amel Book. However, you should be able to do this without my book, if you use the Amel procedure: (https://amelyachtowners.groups.io/g/main/files/Bow%20Thruster%20maintenance%20A54/A54_Bowthruster%20flex%20coupling%20replacement.pdf).

If it is stuck, like I believe you will find, you will likely need the help of a machine shop and mechanical pullers.
