Hello Alain,
A friend of me make me a prototype of the pulley in a technical plastic, it seems very, very fine, and with plastic NO corrosion is possible !
He test the pulley at 500kN ..

The probem with the AMEL pulley is the MEGA corrosion between the steinless steel and the aluminium.

This caused :
1-My first AMEL poulley was brocken in 3 parts !
2-My second AMEL poulley was not brocken BUT the steinless schaft was in bad condition ....

I am very angry after AMEL because the pulley is of poor quality that the piece is not available, cost for 2 pieces 500 or 600 euros ....

You can contact my friend, he will be happy to buy a cople of pulley

Re: [Amel Yacht Owners] Diesel leak

Craig Briggs
 

Pat - yes, odd all three are leaking; I wonder if maybe they started one at a time and just didn't get noticed. Oh well, doesn't make a difference now. If you unscrew the nipples to add tape, you may be able to replace the O rings instead (or do both). If you've got a shop manual or drawings you'll be able to watch out for other components the nipple holds in. A trick someone gave me is to spray copious amounts of Brake Cleaner around the area before you start - does wonders to get rid of any gritty, oily dirt. 

As Bill mentioned, you're getting into professional rebuild territory, but, hey, if you pull it off you've won, if not, it's they same rebuild you'd have if you took it straight to a shop. My overhaul was about $600 (including injectors). That's more than teflon tape, I think. 

Good luck, Craig SN68

Hi Pat,
I think the conventional wisdom is do not use teflon tape as there is risk of a piece getting loose and clogging things downstream. Paste sealant is preferred. Then again, if you're really, really careful, maybe, but why risk it for a cheap tube of paste.

I've got a Northern Lights, not Onan, but suspect the hpp assembly is similar, with a reducing nipple coming out of the hpp and the injector pipes fastened to the smaller end. If your is like that, can you definitively tell which end of the nipple is leaking? 

On mine, a couple of months ago, it was the larger end at the hpp.  That's sealed inside the hpp with an O ring so I took it to an diesel pump shop to redo - I don't open my injector pumps myself - and it had 7500 hours, so it was due for servicing anyway. If your leak is at the small end to the injector pipe, sure, try some seaant.

Good luck with i t,  Craig, SN68 Sangaris

Pat,

I assume you are talking about the four high pressure feed lines from the injection pump to the injectors.  The following is true, if you have the standard Bosch Injector pump...

First, if you introduce air to the fuel system, you have to bleed at the injectors.

And now to the nitty-gritty...

There are two parts that seal the high pressure at the face of the injector pump, one is a fitting that is screwed into the body of the pump, the other is the high pressure flare-type fitting on the pump end of the injector feed tube.  

The nut on the flare fitting can be tightened.  If you do, be sure to get a wrench on the inner fitting to keep it from turning. For a flare fitting, the sealing surface is the metal to metal flare.  Teflon tape on the threads will do no good at all, and can only cause trouble. A TINY b it of antiseize only on the threads can help with tightening and removing later, but will not help with sealing. A danger here is if over tightening which can crack the tube, and that is a pain to replace.  If you loosen tubes to take them apart, clean everything around them fanatically before you break them open. 

One trick that can sometimes work for a stubborn leak here is to crack open one of these flare nuts while the engine is running, like you do at the injector end to bleed air.  Diesel fuel will squirt out, and if you have lead a good and pure life, it might flush out the tiny bit of dirt that was keeping the metal surfaces from sealing. I realize this is a pain to do on our boats because you have to be a double jointed contortionist monkey to reach it, even if the engine is off.

The fitting that actually screws into the pump body is a very different beast. Normally, these are only removed as part of a n injection pump rebuild. My Volvo shop manual covers the process for removing the injection pump, but that is all.  Parts and service details are all Bosch. I don't have those.

 I have never had one of these apart, but based on similar fittings I would guess they are actually valves sealed at the base with a copper squash washer. Tightening them is not likely to help if the copper washer has been compromised, and teflon tape is an absolute "No" here.  Any parts here are Bosch parts, and I do not believe they are available from Volvo.  The good news is these pumps are very common and not at all specific to this engine. The name plate on the side of your injection pump should lead you to an online parts diagram and list.

Once you start messing with the inside of an injection pump, it becomes a very fussy job.  The tiniest speck of hard dirt can damage parts, clearances are very tin y. Many special tools are needed.  Most  small diesel mechanic shops send these out to specialty shops who have the tools and test bench needed.

I had a similar leak on a similar injection pump on my old boat.  After several tries on my own, I took the whole assembly to the rebuild shop.  Came back as good as new.

Re: Autoprop vs Maxprop and specs of each

Jose Venegas
 

Great story and inspiring to all of us close to making the jump.  I will have plenty of questions about your trip after I watch your videos.

As to the prop, there are three main differences between the Auto and the Max, all affecting performance (at least in theory). 
 I) Autoprop has beautifully shaped blades with an angle of attack that varies radially and becomes smaller as you move away from the shaft. This "twist" is key to increase efficiency and avoid cavitation as it accommodates the changes in relative velocity of the blade with respect to the water that increases with the radius.   In contrast, the blades of the Max prop have no twit; they are flat.  Of course, this reduces the drag when the engine is off compared with the Autoprop.  
2) Autoprop has blades that adjust the angle of attack depending on the speed of the boat.  This maintains thrust during motor sailing even as the wind speed increases.  The auto prop blades have a constant angle of attack and, at constant RPM, the thrust decreases as the speed of the boat increases.  In fact, at a certain boat speed, the thurst becomes zero as the prop just cuts through the water.
3) Depending on where it happens, growth on an Autoprop blade is prone to create much more imbalance and vibration than one equivalent on the Max.

 Although these are theoretical reasons based on fluid mechanics, I don't know the extent to which they affect the fuel consumption or boat speed since I have not made the measurement.  I think the increased drag of the Autoprop during sailing should not be noticeable but the difference in efficiency may be more critical in long passages if motoring or motor-sailing is called for.   So, personally, I prefer the Autoprop for our boat because we tend to motor or motor-sail more than I used to in my previous coastal sailing boat.

Re: [Amel Yacht Owners] Re: Climma A/C saltwater plumbing - I was wrong!

 

Duane,

IMPORTANT DISTINCTION:
I am fairly certain that John Clark is describing the Climma engine room mounted AC compressors found in early model SMs with Climma 2-part ACs. The Heat Exchanger (HX) will be on the compressor in the engine room and not on the Blower/Evaporator mounted inside the boat. I imagine that what John describes is exactly what will happen when the AC HXs are plumbed parallel, whether they are located in the engine room as 2-part ACs, or located in various places inside the boat as Climma Compact 1-part units (like you have).

Re: [Amel Yacht Owners] Re: Autoprop vs Maxprop and specs of each

Colin - ex SV Island Pearl
 

Hi Alan

Thanks for those comments which make me wonder if this is just a prop grease issue??? Let me explain ...
Firstly I should say that this boat has never been cruised before Lauren and I set off 1.75 years ago. Up until before I owned it the previous owner had done just 600 hrs on the engine and half that on the generator in 10 years of ownership, plus employed an Amel technician bi-weekly for 10 years to care for her. Based on this I doubt that I could have any U Drive issues or major prop wear as we have been very careful owners too.

I had originally intended to do my normal 2 year haul-out in Cape Town but we became pinned down by bad weather in Durban unable to get any 33hr+ weather windows to sail down to East London on this notoriously dangerous coastline. Because of this, and with time for the Cape Town haul-out dwindling, I haul out in Durban instead, and did the normal prop wearing bearing replacement, bottom paint, plus lifted the waterline stripe.

On turning the prop blades out the water they didn't seem as smooth as normal, and on top of this, in my rush to get back into the water when a possible good weather window was forming, I did not re-grease the prop. That could possibly be the source of my issues, and rather foolish as I have always been so painstakingly careful to follow each and every step to the letter!! In fact I have never greased this prop as I simply sent it back to Bruntons last time to do the bearing change and grease in their factory.

In order to make a run directly for Cape Town (900nm approx) I sailed out of Durban early into the end of the previous SW front and therefore had to motor sail for a day before we picked up good wind and current. Over the next 3 days we shot down the coast breaking all our past records with 3 consecutive 200nm days with our best ever 24hrs clocking up 225nm!! Great sailing indeed and we ran as hard as we could direct for Cape Town right out at sea with pole out and all sails up until rounding Cape Agulus (most southern tip of Africa) where we had to turn NW into un-predicted 30kts head wind and 4+ knot adverse current making for hard motoring to maintain just 3 kts forward motion. When I say hard, that means max 2000 RPM on the Yanmar 75 (very seldom would I ever run the motor above this).

It was at this time that I noticed more prop noise and that there was a slight resultant vibration on the top of the UDrive unit only, not on the main engine side at all. We immediately reduced to usual 1400 - 1600 max revs and crawled into Cape Town to ensure no damage could be done. At those revs there was absolutely no vibration visable at all.

I will drop you a personal email sometime regarding the Indian Ocean crossing as it has been awesome and I hghly recommend it, but course you can also follow our videos on "Sailing Island Pearl" https://www.youtube.com/channel/UCmvAE1BtOM7J8orw237BDgQ?view_as=subscriber , but in summary from far east Indonesia through Singapore, Malaysia, Thailand, Maldives, Chagos, Rodrigues, Mauritius, Runion, Madagascar and now South Africa we have spent 1.75 years in the Indian Ocean and absolutely loved every minute of it. We have faced 50+ knots, 6m+ seas and this boat has been unbelievable as it never ever felt unsafe or out of control to either myself or any crew on board. These are outstanding boats indeed and I learn to respect Captain Amel more and more every day that I sail and live aboard the Amel Super Maramu.

Hi Colin,


i don't know where that information came from about later SMs having Maxprops.
Elyse is 2004 and we have the Autoprop.
i changed the bearings 4 years ago, even though there were no issues. It wasn't a difficult job with the right tools.
 We've since put 1300 hours on the engine and no problems with the Autoprop, no strange vibrations.
I grease it every time we are out of the water for whatever reason.

We'll do the bearings again next haul for C-drive, antifoul etc.

How was your Indian Ocean crossing ?

Cheers
