Re: TMD22 Emergency Shutoff
Craig, Well, maybe we are both right. There is a Volvo part with a pull cord, but not as foolproof as what the captain installed on your SN😀. Actually, I can't believe this part! I am sure it is expensive from Volvo!

Thank you all for the information provided. The problem is solved. Setscrews set against the stainless steel of the tool. I used three.

I'd be surprised that a piece of string was a Volvo option - I'm stickin' with Captain Henri having installed it. Cheers, Craig

Re: Question about the Amel bow thruster removal tool
Thomas is correct. Early model tools had a Stainless end, later model tools had black plastic. Early model tools were designed with holes larger than 8mm, with the set screws designed to be threaded into the bow thruster tube and through the hole in the tool. Later model tools with the black plastic had grooves for the set screws. My guess is that what you have is exactly what you should have. Please also refer to my earlier photo.

It is possible that what you have is not made by Amel. Here is a photo of the Amel-made tool and set screws: The above is for a SM, I am not sure if it will fit a SN.

Re: TMD22 Emergency Shutoff
Craig, Photo when you get a chance. My problem was someone else was asking me by phone. I knew where it was, how to operate it, but didn't have a drawing or photo to send to him. And, by phone, I couldn't describe it well enough for him to find it. In his case it wasn't painted red. Additionally, the manual I had did not have an illustration. Fortunately, Kent emailed me a drawing. Craig, I believe the stop cord was a Volvo option, at least I remember reading that yesterday. It is important to not only know where the lever is, but to ensure it is painted red and you have tested it. The Yanmar(s) and Onan(s) mechanical shut offs are painted red. The Volvo D3 has a red stop button on the stbd top side of the engine. The Onan will shut down when Master Battery switches are turned OFF, or either the red Emergency or 12 volt switches on its panel are turned OFF. Like the Onan, the D3 requires 12 volts to run, but it will not shut OFF with the Main Battery Switches turned OFF because the D3 will self-power from it's 12 volt alternator.

Re: TMD22 Emergency Shutoff
Bill and all,
On our SN there's a light line (or cord) tied to the hole in the injection pump lever and run to a hole drilled in the lip of the engine room hatch opening. You just lift the hatch and pull on the cord - no need to go anywhere near the engine. I'm next to certain that Captain Henri installed it himself. Craig, SN68 Sangaris.

of the shaft from the centerline which pushed the lip seal sideways and, because the Amel recommended seals are made of a hard material, it opened a point of water entry.
I proceeded to test my hypothesis and ordered two special seals made of silicone from a soft seal manufacturer (SSP Inc). It took several months to get them due to the small number of units I ordered (just 2) but, after I installed them three
years ago, I had no more leaks and my bilge has been dry ever since. The cost for the two seals was $72.50 and, more importantly I have not had to change them or the donut seals since I installed them. I have checked them and the donut seals and they are
all still in good shape.
As I am preparing Ipanema for our long term cruise, I am ordering a few spares to carry with me and I will be happy to order some extra ones for any body that wants to try them.
I missed taking pix before installation but here are pictures of them installed, before and after adding the top donut.

Re: Bow thruster motor.
Andrew & Kate Lamb
Hi Chris
I had a very similar problem and ended up having the commutator rebuilt by a local French company that normally services lift motors and wind turbines however one important thing to check is the state of the solenoids - we changed
these also, the engineer reckoned the problem was probably originally caused by poor contacts in the solenoids which in our Amel were also in the bow thruster compartment . No problems since.

The Leroy-Somer bow thruster motor on my SM Pure Magic failed with sparks & some smoke from within the commutator cage. There is just one rewind facility locally which I used having heard from Amel that the motor is no longer in production, and there is no
reserve stock of motors. After rewind repair of heat damaged armature windings (the field coils were also rewound because of lesser, indirect, heat damage) the motor was demonstrated to run smoothly, both forwards and in reverse for about one to two minutes.
Reinstalled on the boat, having taken every care to make the correct connections to the Albright contactors the motor ran for about a second before showering sparks. Back to the rewind facility, a second repair, followed by a successful test run and similar
failure once again. With options running out, I trespassed into the unknown and dismantled the top end bearing housing and brush mechanism after checking for continuity ( present ) across the DI/D2 power leads which supply the field coils, but found no continuity
across the A1/A2 leads for the armature windings. Checking for continuity across the commutator segments showed multiple connections between segments, but with no ordered pattern such as you would expect if the current path follows the intended route between
conductors and segments. My conclusion is the commutator is shorted in many places and I do not think this is repairable, certainly not locally.

Re: Bow thruster motor.
jlm@jlmertz.fr
The engine of the Leroy-Somer thruster is not reliable. I think it is used in dumpsters, you should, I think to find spare parts.
For my part I broke the engine shaft! The breakage was due to a mechanical fatigue of the metal of the shaft which is under seized.
In your case it may be better not to spend too much time repairing this engine and change to a new one.

Re: TMD22 Emergency Shutoff

Yes, stopping the air input does work, but…it can be seriously hazardous to the palm of your hand if you do it by hand as the depression is quite strong. On the other hand (pun intended), if you use rags, they will be sucked into the engine. So some caution is necessary with this method.

Re: TMD22 Emergency Shutoff
Danny and Yvonne SIMMS
Hi, This is not a light weight topic. There are serious dangers involved. First. The comment about shutting off the fresh air supply. I presume this reffered to blocking the air intake. A hand put over this at reves would almost certainly result in serious injury. The suction on a reving diesel engine is considerable. Secondly, in an emergency shutting the fuel off would be way too slow. The lever on the side of the injector oump is the only safe option snd every operator should be familar with this. Diesel engines in some circumstances can run away rev. Also consider being in the engine room and an emegency happenned, something around the drive shaft, a burst water hose or any thing else that might require instant reaction. I commend to all owners to identify their emergency shut off and practice using it. Regards Danny SM 299 Ocean Pearl
