Re: [Amel Yacht Owners] Diesel leak

Patrick McAneny
 

I just want to again correct my previous post ,where I said the pump was connected to the block. I now realize after watching You Tube, that the pump is held in place by four bolts and is located on top of what I thought the pump was. I watched a few videos where guys took out the valves ,replaced two O rings and reinstalled the valves ,bled the lines ,no problem and no need to remove the pump.
Thanks,
Pat

Craig, I just took my neighbor out to the boat for a look see. He works in a nearby marina and is very knowledgeable about almost everything . He thinks as you that we should mark the location and turns ,take the valves out ,replace the O rings and reassemble. I am more inclined to do this, now that it appears that the pump and block are one piece . I did not notice this earlier ,but my friend was looking at how to take it off and discovered it was one piece. He believes you would need to take the front and top covers off of the pump and rebuild in place. 
Thanks,
Pat

Pat, That comment from the shop may have a tad bit of hyperbole. Yes, I think there is a shim under the nipple, but why not pull, seal and replace one at a time and see what you get into? You can always bail out and take it to the shop (or pay the freight for them to remove it).

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). Tha t'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 75 00 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

I have discovered that all three nipples screwed into the high pressure pump are leaking around the threads. I have a Volvo TMD22a . I could only get a wrench on the one on the end and tightened it a bit, but still leaking. I was told that I should reinstall them with teflon tape  around the threads. Would this be the recommended way to go? I am afraid a sealant may find its way into the system. Secondly, will I be able to bleed the air at the pump , or will I need to bleed the system at the injectors ?

Hi Pat,
Hmmm, I never met an injection pump that didn't come off the engine, and rather easily, but, as I mentioned before, I've got a Northern Lights, not an Onan (although I think they may share the same pump). 

On mine there are 4 bolts after you pull the pipes and the shut down relay mechanism, the pump then pops off as a unit. Yes, it does kind of look like you're taking off a cover, but it's an integral unit, open on the back so the injector pump pistons get lubricated by the engine oil splash.(That is, when you remove it, you'll see into the engine crank area.)

Sounds like you're making progress, though. Will be interested to hear how you make out. How great if it turns out to an easy-peasy fix!
Cheers, Craig

On my old boat, I saw what you experienced many, many times.  I was initially extremely concerned, as one should be.  But then one day my boat got unplugged from shore power by the dock staff, and that night after plugging it back in I was awakened by the CO alarm..  There had been nothing on board that produces CO in many days.  After much experimentation, I proved to my own satisfaction that the CO alarm was actually sensitive to hydrogen gas produced by the batteries when they were excessively charged.  It seems this is true for many CO alarms.

Take the alarm seriously.  Air the boat out well, and take care not to let exhaust inside.  But also check to see if your battery compartment ventilation is working correctly, and also check that your batteries aren't overcharging.  Some chargers will keep the voltage too high even though the batteries are full because other loads (e.g. refrigerator) are making the charger believe the batteries are still accepting a lot of current.

We motored home for about six hrs. on Monday ,closed up the boat and went up to the house. Tuesday I went out to find the carbon dioxide alarm beeping in the aft cabin. I took it outside the reading went fro 500 or so to zero,took it back in and it went up again. So be aware of fumes entering the boat while motoring,if one was sleeping in the aft cabin for many hours while motoring it could have a bad outcome. I remember about ten years ago , a little girl died nearby while sleeping on her grandparent's motor yacht while the generator was running. The fumes apparently entered thru a forward hatch.

Hi Colin,

great that you are going so well. There were queries on the forum a while back about when to reef, when to heave to, and when to wish you were not there. Your experience mirrors mine. The SM is a phenomenal off shore design and she looks after you in conditions where other designs are in trouble or at the least giving the crew a hard time. We did a big crossing (1200 miles, 200 a day) in boisterous conditions and all my crew including Yvonne agreed if we lived to 100 we would never get a dream run like that again. A Beneteau 50 came in after us saying, "Oh my God, it was hell out there" Horses for courses. Is your wife (sorry forget her name) doing the passages with you? As to greasing the prop. Mate of mine once said to me, grease and oil are the cheapest spare parts you will ever buy. I have greased mine in water easily (so long as you are not prone to dropping little screws). The trick is to have several spares, then you will never drop one.

Kind Regards

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 ?

Re: [Amel Yacht Owners] Diesel leak

Craig, A rebuild shop told me that once removed ,it is essential that adjustments be made and set properly to function. Now my problem is to remove the pump, not an easy job to access the bolts and to disassemble. It is crazy that all three are leaking,I wish I had more time to tackle this,the clock is ticking.
Thanks,
Pat

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

Craig, The reason that tape was suggested was the concern for sealant clogging things up,which made sense to me. The leak it just around the male threads as they come out of the H.P. pump. , funny all three are leaking.

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 75 00 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

I have discovered that all three nipples screwed into the high pressure pump are leaking around the threads. I have a Volvo TMD22a . I could only get a wrench on the one on the end and tightened it a bit, but still leaking. I was told that I should reinstall them with teflon tape  around the threads. Would this be the recommended way to go? I am afraid a sealant may find its way into the system. Secondly, will I be able to bleed the air at the pump , or will I need to bleed the system at the injectors ?

Re: [Amel Yacht Owners] High Pitched Alarm coming from somewhere around the Nav Station

Mark Garver
 

Bill, 

Thanks for the reply I just discovered it is the old meteoliner barograph of all things. I didn’t even think it worked since the display doesn’t work not sure what triggered the alarm. With the help of younger ears we pinpointed the noise and was about to remove the panel behind the nav station and when moving to box we unplugged it and it stopped.

Thanks again!

Mark

Re: SM Turnbuckle

Craig Briggs
 

Hi Paul,
If they are the original turnbuckles from ACMO, that Amel uses, they are chromed bronze, not stainless steel. Brother Joel insists the best practice is to replace all turnbuckles (& clevis pins, etc.) whenever you do the rigging. He also recommends switching to mechanical fittings like Norseman or Sta-loc, at least on the bottom ends, rather than the swaged fittings that Amel/ACMO used originally. He's got a point.
Cheers, Craig SN68

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.
